(graduation committee); Jalali Sohi, A. (mentor); Hall, Daniel M. (mentor); Delft University of Technology (degree granting institution)","2024","A construction project is inherently complex, involving numerous stakeholders, lengthy timelines, and intricate relationships, leading to significant risk potential. The increased complexity of construction projects and the fact that a large percentage of projects are still delivered with significant delays and cost overruns has led to the necessity of applying different methods by the project managers and the teams. Agile project management is an example of that as its implementation in construction projects can help increase flexibility, achieve continuous improvement, help the project stay on track without schedule overruns and achieve an overall improved quality through effective collaboration and constant feedback. Despite agile project management's flexibility and continuous improvement benefits, its integration with risk management remains underexplored in the construction industry.
The objective of this study is to propose a framework that could help improve the risk management project by offering a more proactive approach and at the same time enhance people’s engagement with risks. The goal of this thesis project is to support construction companies in approaching risk management in a way that incorporates agile methods.
Implemented in a project and evaluated through questionnaires and a focus group, the framework showed promise in elevating risk awareness and fostering interdisciplinary collaboration. However, incomplete implementation of some elements limited definitive effectiveness assessments. Subsequent expert judgment sessions confirmed the framework's potential in proactive risk identification and management, alongside the initial findings of heightened awareness and collaboration. Recommendations for improvement include clearer risk impact depiction and explicit framework objectives communication. Essential for success are targeted risk training, clear vision articulation, and structured step-by-step implementation supported by project managers and risk coordinators.
In summary, the proposed framework merges agile principles with risk management, aiming to cultivate a proactive risk culture, enhance team communication, and mitigate increase engagement with risks. While showing significant benefits, it also highlights the need for adjustments to fully realize its effectiveness in the construction industry's risk management practices. This study underscores the importance of agile methodologies in enhancing traditional risk management approaches, offering insights for future application and refinement.","Risk management; Agile project management; scrum method; Framework development","en","master thesis","","","","","","","","2025-02-26","","","","Construction Management and Engineering","",""

(mentor); Della Santina, C. (graduation committee); Delft University of Technology (degree granting institution)","2023","Legged animals possess extraordinary agility with which they can gracefully traverse a wide range of environments, from running through grasslands to jumping across cliffs and climbing nearly vertical walls. Inspired by this, in this work, we use Deep Reinforcement Learning to give legged robots the ability to perform a diverse set of highly explosive and agile jumps. Unlike other works, our approach is not constrained to imitating a reference trajectory. We instead use curriculum-based learning to progressively learn more challenging tasks, starting from a vertical high jump and then generalising to forward and diagonal jumps. In the final curriculum stage, the robot learns to leap over barrier-like obstacles or to land on them, conditioned on the desired jumping distance and the object's dimensions. We show that such an approach can produce a wide range of robust and precise motions, which we thoroughly and successfully validated in several indoor and outdoor real-world experiments on the Unitree Go1 robot. In our real-world experiments, we show a forward jump of 90cm, exceeding previous records for similar robots reported in the literature. Additionally, we investigate the effects of incorporating bio-inspired parallel elastic actuators to improve the jumping performance further. This resulted in smoother motions, much softer landings with lower joint velocities and larger jumps. Finally, we present and analyse the limitations of our method and introduce exciting directions for future work to address them.
This research aims to fill this gap by examining the perceived impact of adopting agile methodologies in technology-driven projects within asset management firms in the Netherlands through a qualitative study using thematic analysis through semi-structured interviews and document analysis. The study aimed to gain insights into the reasons, challenges, benefits, success criteria, and key factors influencing project success in the context of agile implementation. Through interviews with experienced agile team members, valuable insights were obtained. It was found that agile methodologies are not the sole cause of project success, as success is influenced by a combination of factors. Agile methodologies empower teams to adapt and respond to changing circumstances, providing a solid foundation for handling challenges and embracing positive change. The research highlights the importance of having the right people with the right mindset and behaviour in key positions within the organisation. Teamwork and acceptance of other contributing factors are at the core of agile methodologies. Agile provides a framework for effective collaboration and flexibility, enabling organisations to leverage its benefits and improve project outcomes. The findings emphasise the need for alignment between the organisation's culture and the principles of agile methodologies. It is crucial to create an environment that fosters teamwork, encourages open communication, and supports continuous improvement.
The research findings reveal that asset management firms adopt Agile methodologies in technology-driven projects for various reasons, such as increased flexibility, faster delivery cycles, improved collaboration, and better adaptation to changing requirements. However, challenges related to resistance to change, stakeholder alignment, and the need for continuous learning and skill development were identified. Despite these challenges, the perceived benefits of Agile were evident, highlighting its ability to enhance project outcomes. The criteria used to measure project success in technology-driven projects within asset management firms encompass a combination of quantitative and qualitative factors. While meeting project timelines and budgets was important consideration, other success indicators included customer satisfaction, quality of deliverables, stakeholder engagement, and adherence to project goals. This multidimensional approach to measuring success reflects the complex nature of technology-driven projects in the asset management sector. The research identifies several key factors that influence project success in technology-driven projects within asset management firms. These factors include effective teamwork, strong leadership, clear communication, stakeholder involvement, and the alignment of project goals with organisational objectives. The findings emphasise the critical role of these factors in overcoming challenges and ensuring successful project outcomes in the asset management industry. The experiences and perspectives of agile team members shed light on their perception of best practices for using agile methodologies in technology-driven projects. They emphasise the importance of continuous improvement, transparency, and adaptability in Agile adoption. A supportive organisational culture, ongoing training and development, and effective collaboration between team members and stakeholders are identified as crucial elements for the successful implementation of agile practices. These insights from agile team members provide valuable guidance for optimising the use of agile methodologies in technology-driven projects within asset management firms.
The research concludes that agile methodologies, when implemented effectively and supported by the right organisational culture and mindset, can significantly enhance project success in technology-driven projects within asset management firms. It is recommended that organisations invest in developing and nurturing the necessary skills, behaviours, and mindset to fully leverage the potential of agile methodologies. The study contributes to the existing body of knowledge by providing insights into the perceived impact of agile methodologies in the specific context of asset management firms. The findings can guide organisations in making informed decisions regarding the adoption and implementation of agile methodologies to enhance project outcomes.
A literature review has been conducted on the success factors and barriers of agile implementation in the hardware environment. Furthermore, the benefits and challenges of the use of agile are investigated and an overview is created. Moreover, a qualitative research approach is used to dive into the perceptions and best practices of agile by doing a case study with multi-person interviews at a large hardware development company. The findings of the success factors, barriers, benefits, and challenges are identified and compared with the literature. Remarkably, the success factors and barriers are difficult to see independently of each other, as they are often linked and can reinforce one another.
The way of implementing and using the agile method must match the company and the people. For the implementation, the mindset of the people should be right in place and the pilot can show if the proposed way of working is right. For the use, it is of significant value that besides the people aspect, the tools, and organizational structure are aligned. Also here, the rituals, prototyping, training, and way of specialization should match the company and the teams. The findings of this thesis can be used as a guideline to implement and use the agile methodology in large-scale hardware companies.","Agile; Hardware; Implementation","en","master thesis","","","","","","","","","","","","Management of Technology (MoT)","",""

(mentor); Hultink, H.J. (graduation committee); Delft University of Technology (degree granting institution)","2023","Background: GFI was a global financial institution. An innovation methodology, DTLSA, was created for GFI through the integration of Design Thinking, Lean Startup, and Agile/Scrum software development. Signs of a low-level adoption for DTLSA were witnessed internally, despite ongoing promotion efforts.
Objective: This project aimed at improving the DTLSA adoption at GFI through empirical research and design intervention (directions). First, an investigation was needed to validate the potentially low-level adoption of DTLSA and to analyse different aspects of the DTLSA adoption status quo. Then, barriers and enablers for DTLSA adoption were sought out in pursuit of a better understanding of DTLSA adoption. Furthermore, the contextual information gathered in empirical research was used to inspire the design process for potential improvement concept directions.
Research methods: A mix of different research methods were used to achieve a holistic understanding of the topic: literature and existing knowledge study, group session, interview, and survey.
Research results: The low level of DTLSA adoption was confirmed, despite the positive aspects of DTLSA adoption such as sufficient understanding, and high motivation at GFI. A variety of barriers and enablers were found, the majority of which were related to 2 significant factors: team autonomy, and team engagement. 3 growth stages for DTLSA adoption were identified regarding the different levels of these 2 factors. Team autonomy at risk caused by multiple barriers was considered the most pressing issue that led to the low level of adoption.
Design: The design problem was defined as empowering the ambassador figures who emerged in teams during the DTLSA adoption. A storyboard of a possible current situation and an imaginative narrative of an ideal situation was created. 3 concept directions were proposed.","Combined approach; design thinking; Lean Startup; Agile Software Development; Organizational Adoption; Innovation transformation","en","master thesis","","","","","","","","2023-05-31","","","","Strategic Product Design","",""

(mentor); Happee, R. (graduation committee); Bertipaglia, A. (graduation committee); Delft University of Technology (degree granting institution)","2022","This thesis describes the concept of a reconfigurable wheelbase for a car as a way to improve agility at higher velocities. Altering the longitudinal position of each wheel with respect to the centre of gravity, leads to a change in lateral wheel forces. This affects the car's yaw rate, therefore making it possible to influence its agility. Available literature has shown that this subject is still quite weakly investigated, which makes it an interesting topic of research. To investigate this influence of actively reconfiguring the wheelbase, simulations were done using IPG Carmaker together with MATLAB/Simulink, during which a simplified vehicle model of a Toyota Camry was used. A proportional derivative controller combined with control allocation was designed to regulate the reconfigurable wheelbase system. It features a reference generator that returns a desired yaw rate and activation logic which ensures that the controller is only activated in a velocity range of 60 km/h to 110 km/h and when a steering input is given. Furthermore, a benchmark study is designed, using a fuzzy logic controller that is based on a simplified version of one presented by Soltani et al. (2017). This controller uses the same reference generator and activation logic for consistency. The rules and membership functions of the fuzzy logic block are adopted from the mentioned paper. The performance of both these controllers and a baseline vehicle without any control, are evaluated for a step steer manoeuvre, an increasing circle manoeuvre and a double lane change, at different velocities and/or steering amplitudes. Based on the results of these tests, it is shown that both controllers are able to influence the lateral dynamics positively during most of these manoeuvres and are therefore able to improve the vehicle's agility in the velocity range in which the controller is active.","reconfigurable wheelbase; lateral vehicle dynamics; vehicle dynamics control; vehicle agility","en","master thesis","","","","","","","","","","","","Mechanical Engineering | Vehicle Engineering | Dynamics and Controls","",""

An important factor contributing to these cost overruns is the mismatch in the approaches of IT-architects and agile software development roles. In literature there are hints that complementary added value could be achieved from interaction of these roles. For practitioners there is need for governance strategies that improve the added value of combining these roles and their approaches in a complementary way. To identify how governance strategies help to obtain complementary added value from IT-architecture and agile software developer interactions this research used a multi-case study approach with exploratory and theory building focus. Interviews with IT-architecture and agile developer roles were used to collect data and compose case studies. This approach allowed to identify governance strategies with governance strategies that were used in practice. Multiple cases were chosen to analyse governance strategies across cases, which improved generalisability. The results include a topology of interaction models, a set of added value and problems found in the cases, related to their interaction model and a set of descriptions of governance strategies that could be used to achieve complementary added value from the interaction of software architects and agile development teams.The case studies and results provide practitioners with the opportunity to update their knowledge and change their perspective on interaction of IT-architecture and agile development roles.

The context of focus was a specific technology unit within Nike, Inc.
The main research question is formulated as follows:
‘How might we use Design Thinking to our advantage in the agile software development context of the targeted Nike Technology unit?’
Recognizing that Design Thinking is a contextual concept that needs further adaptation to contextual user needs, literature research and context analysis are done towards Design Thinking, agile software development, and related opportunities and boundaries.
Research findings following the interviews indicate three main areas of concern that form boundaries to problem exploration: having a solution-oriented rather than a problem-oriented mindset, organizational structures that limit the space for problem exploration in terms of time, processes, and the role of technology in the problem exploration phase, and the need and importance of having a clear and aligned vision.
Literature and exploratory research findings are integrated, answering the research question through a conceptual model covering three key principles: problem-oriented and human-centered thinking, dynamic alignment towards strategic fit, and divergent thinking to consider more fit-for-purpose alternatives.
Subsequently, the conceptual model is translated into a usable artifact: a Problem Deep Dive Canvas accompanied by a Problem Deep Dive Tool Guide. The product aims to support product managers and product owners to put the key principles of the conceptual model into practice in collaboration with agile software development teams and business stakeholders.
The threshold to use the product is low as there are no significant conflicts with current structures and processes. Initial validation results are promising towards feasibility, desirability, and viability of the product. Using the canvas on actual requests already showed that the outcomes of the canvas potentially significantly impact the further trajectory of the intended projects.","Design Thinking; Agile Software Development; Problem Exploration","en","master thesis","","","","","","","","","","","","Strategic Product Design","",""

The developed tools, frameworks, and models in the literature take a rather technical perspective on the problem. The scholars focus primarily on mechanisms that provide accurate and relevant information retrieval from the requirements database or analyze various techniques for creating valid links between requirements. Although the technical approach provides solutions to several scoped challenges, the scholars did not take into account the business goals, stakeholders’ needs, and business processes. In practice, the company resources, the development approach, and knowledge workers’ interests play a critical role in requirements traceability. As a result, multiple tradeoffs are required to develop a balanced and stable environment. In particular, the approaches are not in sync with agile development approaches, whereas the first requires documentation, the latter is focused on working software. Therefore, taking a business and management perspective on requirements traceability integration in Agile methodologies could bring new meaningful insights into solving existing challenges.
Management requires to make trade-offs between what is desirable and feasible given limited resources and the need to stay agile. As a result, a framework for making these trade-offs is developed. In addition, a model capturing the main elements needed for traceability is designed, which can be modified/customized by other companies to realize RT given the limitations (or no limitations) brought by resources and business goals/strategy.","Agile; Requirements Traceability; Business Process Modeling; Business Process Management; BPMN; Small and Medium enterprises; Management","en","master thesis","","","","","","","","","","","","Management of Technology (MoT)","",""

They are collaborating with the EU-Horizon 2020 COALA project to develop a cognitive intelligent assistant for the production line. They expect to standardize activities in the production line to reduce the gap in activity performance between experienced and novice operators. In order to set up the cognitive assistant, an operator location tracking system was needed to identify issue hotspots and sequence of activities in the production line. In this project, a suitable motion capture system was explored and deployed at Diversey Enschede 5L/ 10L production line. A literature study was performed to compare the state of the art motion capture and motion analysis methods. From the literature study results, the project decided to deploy a markerless motion capture method using Zed 2 camera.
The data collection method was tested at Enschede with Zed 2 camera which has in-built object tracking algorithms. The project applied an ethical approach to operator tracking, giving due respect to operators’ privacy concerns and anonymity. The Value Sensitive Design method was applied in this project to identify the stakeholders, their values, and the project’s future speculation. The data collection, storage and upload to cloud server was conducted using indefinitely running Python codes. The tracking was anonymized by allocating random identification numbers to denote objects and thereby, no personal data that can identify the operator were being stored. The data was captured and stored in spreadsheet format and processed using Python. The project concludes with the implementation of Z-Dash, an interactive tool that visualizes the data in various meaningful representations. Z-Dash offers graphs such as the Spaghetti chart for visualizing operator location and movements, Heat map of operator location concentration and Pareto chart that visualizes time and frequency of visited stations. The tool was evaluated with participants from Diversey to estimate the usability, interactivity and effectiveness for process improvement.

(graduation committee); van Erp, J. (mentor); Delft University of Technology (degree granting institution)","2020","Policymaking regarding Artificial Intelligence is threatened to lag behind, and the Dutch Ministry of Justice and Security stated its desire to catch up. The longer we wait, the wider the ‘gap’ will become between regulation and market development. In order to keep AI technology beneficial, a human-centered design approach should be key not only in AI development, but also in policy development. Instead of focussing on ‘what is possible’, we need to empathize with stakeholders to unravel the latent needs that define the public values of today. Along with the unfamiliarity of AI technology and its unpredictable consequences, this calls for a transition towards an agile government. This transition represents a shift from ‘assuming’ to ‘learning by doing’, from ‘is it safe?’ to ‘is it safe to fail?’, and from 'reactive' to 'proactive' policymaking. This thesis proposes proactive policymaking as a creative, iterative and future-oriented exploration. AI experiments should be framed as a priority vehicle for organizational learning. Experiments are used to empathize and unravel its desirability early in the process. Policy Provotypes and Minimum Viable Policies are created as first feedback loops prior to current feasibility studies. An ‘Desirability panel’, covering the experiences of a representative group of society, reduces blind spots and offers transparency. It facilitates short-line communication and alignment. Potential policy interventions transcend theoretical discussion as the demonstrated experiments provide a context for detailed dialogue. Policymaking will be less affected by the media's magnifying glass as stakeholder inclusion is at the heart of policy development. This vision calls for the need of a Creative, Empathic, Transparent, Inclusive, Future-oriented, Iterative, Experience-driven and Demonstrative approach. Therefore I present the acronym: CERTIFIED. The CERTIFIED approach covers a theoretical framework for agile policymaking. In essence, it is about the ability to adapt quickly by providing a window for feedback by the public early-on in the process and embracing criticism as a valuable gift. An iterative design process led to (1) the creation of the CERTIFIED Manifesto for the ministry, that publicly declares the needed transition mindset, and (2) a practical toolkit to offer policymakers an actionable way to carry out the first steps. The toolkit resembles a low barrier to demystify the desirability of AI application scenarios with a representative group of society. This toolkit contains a Perspectives card deck and a set of 6 canvases. The card deck includes 15 stakeholder cards to empathize with their values, roles, concerns and power. The canvases guide the panel in the steps of Design Thinking and capture the insights from the dialogue. A final toolkit pilot with representative stakeholders of the Quadruple helix showed a cross-fertilization of knowledge and expertise resulting in the ability to identify their blind spots and to formulate a ‘Minimum Viable Policy’ and test set-up to validate their assumptions. This research concludes that if space is provided for proactive policy experimentation, this would give policymakers momentum to reflect on the long-term goals instead of the issues of the day. Thus, offering a way towards becoming an adaptive government.","Policy Development; CERTIFIED; regulatory framework; proactive; transition design; systemic design; Human-Centered Design; Manifesto; Toolkit; Agile","en","master thesis","","","","","","Introducing part of the research during INNOvember, a conference organized for and on behalf of the entire government: https://vimeo.com/476623859#t=870s","","","","","","Strategic Product Design","",""

NanoSat laser communication terminal (LCT) promises 1 Gbps data downlink capabilities. However, LEO to ground free space optical data transmission requires precision attitude knowledge under agile ground target tracking conditions. Under such stringent operational conditions, the calibration of gyro-stellar misalignment and scale factors is a well-established practice for traditional satellites. Nevertheless, the impact of such non-idealities in the context of MEMS gyro-stellar based NanoSat precision pose estimation is unclear. Furthermore, the gyro-stellar calibration performance that can be achieved with NanoSat ADCS system requires further investigation. Under agile operational conditions, slew rate induced star tracker drop-out is common for NanoSats, which limits the operational envelope of agile precision tracking missions. To increase our understanding of attitude knowledge estimation capability of today's NanoSats, this thesis work is extended at Hyperion Technologies. In collaboration with Hyperion Technologies, gyro-stellar sensors are characterised; and CubeCAT LCT is used to laydown the reference payload and mission requirements of an agile precision terrestrial target tracking NanoSat mission. Based on state steady noise PSD properties, and attitude knowledge requirements set by the LCT, gyro-stellar configurations are selected, and characterised. A rigid body attitude simulator is developed, considering the characterised sensor suite, to generate representative nominal and non-ideal sensor outputs under four different mission phases: 1.) Inertial pointing with no angular rate, 2.) Non-harmonic sinusoidal manoeuvres 3.) Agile precision ground target tracking and 4.) Inertial target tracking with non-zero angular rate. Reaction-wheel time delay and torque limits are evaluated to analyse the feasibility of attitude pointing requirements under agile target tracking conditions. Due to favourable properties of robustness to large initialisation errors, fast convergence, and preservation of attitude quaternion unity norm constraint; UnScented QUaternion Estimator (USQUE) variant of UKF based filter is synthesised for attitude estimation. The USQUE filter is further extended to facilitate the calibration of gyro-stellar misalignment and scale factors. It is demonstrated that the presence of gyro-stellar misalignment and scale factor, and star tracker occultation under agile slew rates significantly deteriorates the attitude estimation performance of USQUE based attitude estimator. Star tracker misalignments and dropouts are observed to have a significantly larger impact on the attitude knowledge estimation performance, when compared against MEMS rate-gyro scale factor and misalignment. Degraded MEMS rate gyro sensors are observed to have little impact on the attitude knowledge estimation performance of 6/7 state USQUE filter. However, it has a considerable impact on the convergence performance of star tracker misalignment calibration.

Using this set Scrum was developed as a agile framework in the early 1990s, which still remains the most popular framework today. However, Scrum originated to be used by a small number of co-located teams. When the amount of teams and the distance between the teams becomes bigger, issues will start to arise. With the rise of the computer and internet, programming-related work environments have become very large and globally distributed, implying a friction when using agile in these environments. This study aims to explore what challenges occur when using agile in very-large globally distributed environments and explore for practices that can be used to deal with them. To do this, a variety of research methods is used to gain insight, those being a systematic literature review (SLR), interviews and online surveys. We identify 50 challenges that may be encountered and 72 practices that can be used to combat them. Our online survey verified that all found challenges are frequently encountered in practice and the majority have a significant impact when encountered. However we also identified multiple practices that are used often to combat certain high-impact challenges. The most important practices were identified to be training and coaching. Experts were invited to fill in an online survey to generate possible learning goals. These learning goals are used to create an education program prototype for very-large scale globally distributed agile software engineering. As examples, 4 use cases in different environments are provided to show the prototype can be used to construct a matching training program. We provide proposals for further research directions into challenges, practices and the education program based on the steps taken in this study.","very large scale; globally distributed; agile; challenges; practices; education program","en","master thesis","","","","","","","","","","","","Computer Science","",""

There are various factors leading to design changes, however, the most frequent factor is the client. Clients often produce vague design briefs and as a result, design changes are expected at a later stage, leading to time and cost overruns as well as lower productivity. The objective of this research is to create a framework for design teams, in order to improve the management of changes initiated by the client in the design stage of a construction project. This objective is achieved thanks to the use of Agile Project Management (APM), which offers a proactive approach. The proposed Agile framework is validated on the basis of a single case study, and the findings of the validation show that the Agile framework offers benefits in terms of managing of client’s changes (e.g. potential for minimization of changes, improved visibility of changes, reduction of abortive work). However, there are also barriers that hinder the employment of the framework in practice, such as the contractual constraints and the number of stakeholders that have to be aligned with the proposed way of working. Further research should be conducted in order to investigate the real-world application of the framework.","Agile project management; Design Change; Change Management","en","master thesis","","","","","","","","","","","","Civil Engineering | Construction Management and Engineering","",""

(graduation committee); Delft University of Technology (degree granting institution)","2020","The trends in the high tech sector push towards creating and delivering better products to cope with the increasing demands of the customers. The projects of the high tech sector are referred to as Hardware (HW) development projects, which consist of both hardware and software (SW) development. Many organisations have been using traditional project management approaches for years for such projects. In the past few years, the organisations are considering or in the progress of shifting towards the agile project management approach as it has potential benefits which include high involvement and satisfaction of customers, a better quality of deliverables, and adapt to changing requirements in a project. However, mixing both the traditional and agile approaches can have a significant effect on the performance of the project. As it is possible to integrate practices of the agile method into the traditional project management approach, and when combined, this would improve the functionality of the product less influencing the cost and time. A common framework of the agile project management approach is the Scrum method, commonly used for software development. However, to get full advantage of the scrum method for hardware development, it needs to be tailored to the needs and type of the project. The aim of the research is to explore the application of Scrum for hardware development projects with the objective is to formulate suggestions on elements of Scrum that can be applied in the management of hardware development for the benefit of the projects. A theoretical framework was developed, describing scrum practices and their benefits. The benefits known from the theoretical framework will be used as background knowledge to investigate the fit of Scrum elements in the current management approach. Further, the applicability of scrum practices for HW development is decided based on the agile value and principle; each Scrum practice is related. This research determines the characteristics of the HW development project and the difference between the traditional project management approach and agile project management approach. Also presents the suggestion of scrum practice after considering the inputs from the expert's meetings that can be applied in managing specific complexity/problem.
The study observed the changes in the roles of the PMO before and after implementations of agile with four case studies. The research conducted semi-structured interviews and applied surveys with nine professionals in these different companies. The contribution to science of this study is twofold. First, it contributes to the description of the PMO, enriching the field towards a unified theory of project management. Second, it provides empirical evidence for the changes in roles of the PMO with the introduction of agile.
This study found that there are wide disparities between the roles of the PMOs in different organizations. It also found that PMO performs different functions before and after the introduction of agile methods in a firm. It seems to be consistent that the PMOs are involved in the activities of monitoring, controlling, and standardizing project methodologies in both periods. A common theme across the participants' reports is that the PMOs participation got diminished or repurposed to a supporting and serving role with the introduction of agile. An explanation for this change is the shared responsibility the PMOs have with the agile teams on processes they were the sole or main responsible in traditional settings. Another common theme is the interfacing part the PMO plays, bridging traditional sectors and agile sectors of the firm. Participants in all firms believe the current state of the PMO is not final and expect it to continue to change.

Besides, the existing researches are limited by industry. As agile methodology has been continuing spreading beyond software development projects (Dybå & Dingsøyr, 2008; Serrador & Pinto, 2015), little was known on whether the agile methodology is genuinely contributing to knowledge sharing in the non-software development environment. Based on an in-depth study in Philips Research organizations, by conducting semi-structured interviews with different roles involved in agile research projects, this study investigates how agile methods influence knowledge sharing behavior and its effectiveness. The inhibitors are clustered into environmental, individual and motivational factors based on Wang’s knowledge sharing factor framework (Sheng Wang & Noe, 2010).

Customer expectations have hit an all-time high globally (Salesforce Research 2018) and as such, companies are expected to provide experiences beyond products (physical or digital). This has impacted the way companies must operate going forward, by recognizing and addressing customer involvement throughout the development process. The challenge relies in integrating two seemingly contradicting processes Agile development (fast-paced) and Qualitative Research practices (slow-paced) into a seamless operation. The objective is to include the end-users early in the development process. In this way, Werkspot is able to increase the chances of success of product features by implementing a validation phase prior to development process. This project makes a research distinction into Validative Research (concept or idea testing in an attitudinal level) and Explorative Research (learning from users on a behavioural level). Through the Research Case Studies (Section 04: ‘Research in practice’), Validative and Explorative research methods are tested and accelerated to operate under the Agile work setting from Werkspot. The result is a Qualitative Research Process for Werkspot, through this process, the company can continuously involve users in the development of the platform.
technology act as a whole. The NS has proposed an interior vision for 2025. The goal
of this thesis is to “assess the feasibility of Agile Manufacturing for the interior vision
of 2025”. Is the application of Agile Manufacturing feasible within the organisation
NS? Are the application costs realistic for the company? Moreover, are the changes to
adapt agile production desirable within the organisation? To answer these questions,
extensive research has been done which has been divided into four main chapters in
this report: Discover, Design, Develop and Deploy.
The Discover phase consists of a thorough analysis of the subject by doing desktop
research, field research, interviews and more methods to thoroughly analyse the
subject. Requirements were based on the discovery and the norms regarding the
safety of the EU. Multiple interviews and brainstorming sessions were held with
experts of different backgrounds,
The Design phase focused on the technological aspect of Agile Manufacturing.
Therefore, with a focus on Digitalisation, Fabrication and Design automation, multiple
ideas where created. This resulted in an App and two demonstrations that were
developed in the development phase.
In the Develop phase, the App was designed and programmed to give designers and
engineers a quick tool to process different manufacturing techniques, including most
types of 3D printing. The two demonstrations were made to exploit the possibilities within a type of production. Laser cutting and CFF ( Continuous Fiber Fabrication)
were chosen to press the benefits. The App and two demonstrators were tested on
NS employees for their desirability.
The Deploy phase resulted that the App was well desired. However, more development
is needed to make the App work properly. The Laser cut demonstrator needed more
design attention with regards to aesthetics and comfort. The CFF demonstrator was
not desirable due to its price. Future developments that make 3D printing cheaper,
ecological and quicker to produce would regain their interest.","Agile Manufacturing; Fabrication; feasibility","en","master thesis","","","","","","","","","","","","Integrated Product Design","",""

This has led us to believe that organisational theory and practice from the last decades just does not hold up anymore. They have created organisations that made sense then, but do not necessarily now. Organisations themselves need to change in order to keep up with this sped up world. To achieve better success, many organisations are (constantly) entrenched in large-scale change efforts. However, these do not guarantee improvement, with various studies suggesting only about 25 to 50% of these efforts succeed, and numbers are declining. Given the shortcomings to current organisation design theory and change management practices, a new approach could better link theory and practice to increase practical validity.
Therefore, strategic design is used as a new approach to describe organisations, their design and change processes. The research question following this idea is:
How can strategic design be of value in the understanding of and quest for progressive organisations, their design and the design and realisation of accompanying change efforts, to survive and thrive in the context of 21st century challenges? The research focuses on progressive organisations: those that are as ready for the present and future as possible and that (aim to) achieve three distinct abilities: engagement amongst employees, organisational agility and organisational ambidexterity. The focus on design leads to a new view on organisations as a set of organisational blocks and their connections. The approach, based on literature on progressive organisations, insights into design and prototyping and learnings from practice, is specifically human-centred. Organisations are defined from the viewpoint of the employee. The goal of this approach is to understand the organisation in a different way and make it possible to build a new organisation together with the employees in an iterative manner. The various organisational blocks are: raison d’être, environments, culture, grounding and action agenda. In order to achieve a progressive organisation, built on the aforementioned blocks, lessons from design and practice are combined to argue that the only way to deal with complexity is through iteration and repeated learnings. Based on this understanding, (semi-) controlled revolutions become the new approach to change efforts. The end-goal should not be to design or deduce static organisational plans, but to (constantly) adapt to the changing conditions, with the realisation that not all things can be predicted or controlled. This iteration is depicted in the figure to the left. Given this understanding, a revolution is guided by three principles: going from planned to hacked, not forcing, but inviting people to join the effort and to stop managing the effort, but going viral.
In order to increase the probability of successful change, and to increase the usefulness of this research, a revolution checklist is presented. Together, they encompass all aspects of the revolution that should be actively pursued and monitored. The checklist consists of six categories (depicted above), with various additional elements each. These categories are: be broad about it, approach from all angles, talk about the future, change by changing, take one step at a time and build on 21st century technology.","Strategic Design; Organisation Design; Progressive Organisations; Revolution; Organisational Revolution; Revolution Checklist; Organisational Blocks; Ambidexterity; Employee Engagement; Agility; Iteration","en","master thesis","","","","","","","","","","","","Strategic Product Design","",""

(graduation committee); Delft University of Technology (degree granting institution)","2019","Current and future space missions require agile and reliable spacecraft capable of trailing and keeping the required attitude. Most of the agile spacecraft missions are near-Earth based but some are placed far away from Earth and its influence. One example of such missions is the Athena mission, which requires the spacecraft to perform fast and large-angle attitude slew manoeuvres. Such manoeuvres often imply simultaneous use of multiple actuators such as thrusters and reaction wheels (RWs). A fault in any of these actuators might lead to partial or full damage of sensitive spacecraft instruments. In this research project, a novel model-based Fault Detection and Isolation (FDI) strategy is proposed, which is able to detect and isolate various actuator faults, such as stuck-open/closed thruster, thruster leakage, loss of effectiveness of all thrusters, and change of RW friction torque due to change of Coulomb and/or viscosity factor. Moreover, the proposed FDI strategy is also able to detect and isolate faults affecting the RWs tachometer. The design of the FDI algorithm is based on a multiplicative extended Kalman filter, a generalised likelihood ratio thresholding of the residual signals, and a logic algorithm which unequivocally link the faults to the symptoms. The performance and robustness of the proposed FDI strategy are evaluated using Monte Carlo simulations and carefully defined FDI performance indices. In addition, the influence of faults’ magnitudes, times of fault occurrence, and uncertainties’ magnitudes on the FDI system performance are evaluated. Preliminary results suggest promising performance in terms of detection/isolation times, miss-detection/isolation rates, and false alarm rates. Also, uncertainties on the spacecraft inertia seem to have a negative impact on the FDI performance. In order to fully understand the research project presented here, graduate-level knowledge on rigid body dynamics and kinematics, control theory, and filters applied to estimation might be required. If any of these areas are not known by the reader, it is recommended to read some of the associated literature referenced in the bibliography.","Fault Detection; Model based; Fault Isolation; Agile spacecraft; Reaction Wheels; Thrusters","en","master thesis","","","","","","","","","","","","Aerospace Engineering","",""

Many scholars blame traditional management approaches for cost overruns and delays occurring in current projects. To find solutions, project managers introduce tools from various sectors that have coped with similar problems before, such as the IT and manufacturing sectors. Scheduling has been found to be a main reason for delays and cost overruns. Traditionally, scheduling is done before projects start. Predictions are made for durations, costs and required resources. Project managers impose schedules on subcontractors and apply pressure to prevent delays or cost overruns. This method is characterized by a reactive approach to problems. Short-cyclic scheduling is more appropriate for complex projects than traditional scheduling. Short-cyclic scheduling tools allow operational personnel to schedule their own tasks. This gives them the flexibility to detect problems quickly and act proactively. Besides, recent knowledge from the work floor is applied directly to the schedule. Furthermore, A benefit of short-cyclic scheduling is the possibility to proactively cope with changing top-down requirements and circumstances. Most short-cyclic scheduling tools originate from the IT and manufacturing sectors. However, construction projects during the realization phase differ from IT and manufacturing projects. Which raises the question if construction projects during the realization phase are appropriate for short-cyclic scheduling. Scholars have investigated implementations of such tools but have not clearly formulated criteria for short-cyclic scheduling in ongoing projects. To find these criteria the following research question is formulated: What determines the appropriateness for short-cyclic scheduling of construction projects in the realization phase? The determination of a project’s appropriateness started with a literature study on short-cyclic implementation in construction projects. The literature study resulted in theoretical conditions for appropriate short-cyclic implementation. The theoretical conditions were used as a framework to observe scheduling sessions and to interview project members in two construction projects. The theoretical conditions were a means to structurally investigate problems and success factors in the two projects. The case studies resulted in a list of critical project factors for appropriateness, depicted in Figure 1. These critical factors can be considered the tipping point for a project’s appropriateness. If a project does not possess these factors it is unrealistic to expect a successful short-cyclic implementation.","Scheduling; Agile; Last planner; construction; Realization; Implementation","en","master thesis","","","","","","","","2024-05-12","","","","Civil Engineering | Construction Management and Engineering","",""

(graduation committee); Delft University of Technology (degree granting institution)","2019","Agility is increasingly being used in the public sector as its adaptive approach through short-cycled development could allow public services to keep up with developments in technology and the complex problems contemporary societies face. There are, however, some dilemmas at play when it comes to agility and the public sector’s transparency and stability for accountability. Furthermore, agile projects appear to be less predictable and more likely to go off track. The main paradox of agility is that even though it appears to be at odds with control, it is required for agility to be effective. Besides, public sector bureaucracies come with their own control mechanisms which theoretically conflict with agility. The research explores these phenomena by considering how control over agile processes in the public sector can be enhanced through the use of control mechanisms. By using an explorative and single case study approach with validation sessions the research combines qualitative data from theoretical and practical findings which are analyzed through a Revised Levers of Control framework to provide recommendations for controlling public sector agility. It indicates that the agile process itself is the main means of control for which an extensive list of mechanisms is provided of both strategic and operational nature. Besides, the vast presence of interfaces in the public sector increases complexity while external deadlines and tight budgets provide a clear desire for planning as control. A main recommendation therefore consists of mechanisms to be used to perform planning within agility. The research also showcases that types of bureaucratic control can facilitate or are even required for the agile process to function when it comes to centralized strategic visions on priorities and an organizational vision on implementation of agility. Overall, this implies control over agility in the public sector to be a balancing act between mechanisms associated with ‘pure agility’ and with public sector bureaucracies. Further empirical research into the use and implications of proposed control mechanisms and presence of interfaces in practice would help in enriching the findings and provide more insight into the requirements of different types of public sector organizations to control their agile processes.","agility; public sector; bureaucracy; control","en","master thesis","","","","","","","","2020-03-19","","","","Complex Systems Engineering and Management (CoSEM)","",""

However Hallmark is also under pressure, because the greeting card industry is declining and the younger target group is using more and more social media to send quick messages and to congratulate each other. Therefore, Hallmark should look for new ways to connect the younger target group to its brand.
During this master thesis a product proposal and roadmap will be created to connect a younger target group to Hallmark in the following years.
Hallmark is a creative company with a warm atmosphere. However, they are currently in a dilemma between its retail and online department. Where online sales grow by 5% per year, retail sales decline by 8%. However, retail is still responsible for 80% of the company's turnover. Hallmark doesn’t have a clear strategy what its internal focus should be. Furthermore, Hallmark is already looking for ways to innovate, but these innovations are mainly variations on the current greeting card and not something completely new or different.
However, this is necessary, since the current industries in which Hallmark is active are not the most ideally in the long term. The retail greeting card industry is declining rapidly and the online industry faces a strong competition for both greeting cards and gifts. During this project, routine innovation will be conducted to explore a new industry.
This new industry should connect to the younger target group, who experience problems with relationships. They are insecure and have to deal with a lot of stress. Furthermore, they have not much close friends and this is partly due to social media. There is therefore a need to strengthen relationships. Research shows that this is done best by enjoying experiences together and based on validated models, a new experience model has been developed. This experiences model will be the basis for the new product proposal. In addition to this model, experiences must be easy to consume and fit the target group.
However, Hallmark must also be able to offer experiences, without expensive investments. Therefore, Surprise Night has been developed. Suprise Night is a monthly subscription to a date box, which contains all elements for a surprising date night. The concept is targeted at couples who have been together for a longer period and are in need of new, original dates.
Hallmark is able to immediately start offering these boxes, but because the concept can easily be implemented by other parties, it is important to quickly expand to other target groups.

KADMOS is used to formulate large, heterogeneous MDAO problems and their execution process before they are implemented as executable workflows. This thesis focuses on the automation of a key step in the problem formulation for MDAO systems: the execution process definition, i.e. the order and grouping of the disciplines. Several sequencing and decomposition algorithms are developed to optimize the execution order of the disciplines and their division over multiple processors for parallel execution. The algorithms are verified and validated on thousands of MDAO systems using a scalable mathematical test case. Furthermore, the conceptual design of a conventional aircraft is performed using a novel implementation of the Initiator toolbox in KADMOS to test the algorithms in a realistic aircraft design problem. This showed that the algorithms resulted in a setup time reduction due to the automation of the execution process formulation and a reduced convergence time thanks to the improved usage of computational resources.","Multidisciplinary Design Optimization; Aircraft design; Sequencing; Decomposition; KADMOS; AGILE","en","master thesis","","","","","","","","","","","","Aerospace Engineering","",""

To understand this connection we will use Grounded Theory as a qualitative methodology to interview 20 participants across two organisations. In doing so we present a detailed description of Grounded Theory implementation and the results we obtain from it. The results are used to explore the relation between code quality and agile software development. The results show that team empowerment is the core relation between them. The results are structured in a theory which establishes four core values for achieving team empowerment, conditions that apply to these values and which practices can be applied to stimulate the conditions. The outcomes of the study are further verified using an online questionnaire across multiple countries. The theory will be expanded further to establish theoretical links between Agile best practices and code quality metrics to give teams concrete solutions to improve their code quality scores.","Empirical Research; Software Engineering; Grounded Theory; Code Quality; Agile Software Development; Team Empowerment","en","master thesis","","","","","","","","","","","","Computer Science","",""

ABN AMRO also decided to implement a large scale agile framework tailored to their company. Agile methodologies are known to work well at small scale and in an IT context, however at ABN AMRO they’ve implemented it for over 6000 employees from both business and IT departments. Unsurprisingly ABN AMRO faces challenges within this agile organisation. One area in which they’re struggling is managing innovation in a way that aligns with the flow of the tailored and scaled agile organisation. The objective was therefore; To design solution that better aligns innovation processes with the flow of the tailored and scale agile landscape. In addition, literature on large scale tailored agile transformation and innovation management within financial services firms is scarce. Both areas are relevant, however no research was found that combined these topics. Therefor in this thesis we attempt to find challenges for innovation management in a large scale tailored agile framework. In order to both find an answer to this question and help ABN AMRO the challenge was approached from two different streams. Firstly, a revelatory single-case study on ABN AMRO’s tailored agile framework served to understand how they tailored agile at such a large scale and what the challenges were. Secondly, through semi structured interviews with 18 ABN AMRO employees, their innovation management efforts were investigated as well as the challenges they experience with it. Both the challenges from a large scale agile perspective and the company-wide innovation management were merged into a set of six new challenges; “governance on innovation in the agile organisation”, “deficiency of exploration skills”, “getting innovation on the backlog”, “Lack of clear guidance & leadership on innovation”, “Dependencies & Limited Autonomy”, and “Organisational and Cultural legacy”. Based on these challenges a new design challenge was posited which was to design a solution that stimulates ownership and awareness amongst idea owners in the grid landscape towards customer problems and needs. This solution needed to provide clear guidance to enable autonomous and successful realisation of these customer centric innovations in the product and system oriented agile organisation. As a solution to the design challenge and in order to help ABN AMRO with their innovation management efforts, the “User Needs Integration Canvas” was created which is an innovation process that focuses on bridging the gap between customer needs and the complex nature of ABN AMRO’s agile organisation. This study further finds that agile methods don’t cover the innovation process in full, and thus extra efforts and support should go towards managing incremental innovation, the front-end of innovation specifically. In addition traditional financial service providers carry cultural legacy, lack innovation legacy and explorative competences. The role of the individual, with their skills, mindset and behaviour are imperative in in the journey towards a nimbler and more innovative financial service provider. There is no shortcut in becoming an innovative company, whilst a large scale agile framework is a step in the right direction, still a lot of time, effort and patience is needed beyond this ste","Agile; innovation management; Financial services; Large Scale Agile; Innovation","en","master thesis","","","","","","","","","","","","Strategic Product Design","",""

(mentor); van Nierop, Martijn (mentor); Delft University of Technology (degree granting institution)","2018","Agile management has revealed itself as a management approach that copes with an unclear product scope and fast-changing circumstances. This approach has gained popularity by projects in fast changing environments, such as the information technology (IT) industry. Nevertheless, many companies that adopted agile methods are still structured according to a traditional, non-agile form of organization. Projects with an agile project management approach embedded in a non-agile organization might face numerous difficulties. What these difficulties exactly encompass is not fully understood yet and therefor this research strives to fulfil the following objective: “Explore the interaction between agile project management and its organizational context.”
In this way this research aims to contribute to literature about the implementation of agile within an organization. Next to that, this research provides insight to organizations about how an organization is best aligned with agile. This research uses the term software delivery, since this includes projects as well as on-going activities. This results in the following research question: “What kind of adjustments can an organization make to better facilitate agile software delivery?”
The literature study resulted in a compilation of eleven aspects that are relevant to examine the interaction between agile software delivery and the organizational context. These aspects are used as guidance during the interviews. The interaction of agile with the organizational context is discussed with the interviewees in relation to these eleven aspects, in that way creating an image of the alignment of agile within the organization.
Multiple commonalities are observed over the different cases. Interpretation of the results of the cross-case analysis resulted in three patterns.
The first pattern shows how organizations tend to focus on team level when implementing agile and have the tendency to neglect the organizational adjustments around teams. The organizational surrounding is in this research described as the governance structure around the teams and includes the division of tasks, responsibilities and other governance mechanisms. Several of the interview observations can be explained by an insufficient adjustment of the governance structure.
A second pattern is to what extend agile is understood and how it is interpreted. Some of the interview observations can be explained by an insufficient understanding of agile. Adjustment of the governance structure around the software delivery teams should be aligned with agile concepts.
The third pattern shows that several observations can be explained by the fact that change needs time. Every organization undertakes a transition when implementing agile software delivery to change the governance structure and to understand agile. Alignment of agile within the organization depends on the stage an organization is in during this transition.
Based on these patterns, this research concludes that an organization could consider adjusting its governance structure to better facilitate agile software delivery. When making these adjustments, a sufficient understanding of agile is required to ensure that adjustments of the governance structure are aligned with agile software delivery. Next to that, the implementation of agile and the adjustments of the governance structure can be considered as a transition that needs to be managed pro-actively.
During this graduation project, I have explored how can end-users be better involved in the development process, and how should the involvement be planned so that essential feedback is gathered and effectively put into use, and shared with end-users.
As a Case Study, I collaborated with the AerData, a software company located in The Netherlands, which develops sets of software for the aviation industry. AerData was experiencing similar problems to the ones that many other Agile companies have when dealing with user integration. The research of this project explores user involvement in Agile environment from several perspectives. The phases of the research comprise: A) a literature review of Agile and User-Centered Design, the main problem of their integration as well as the current existing solutions where Agile and User-Centered Design are successfully combined. B) an analysis of how AerData is applying Agile, and how they are involving users for the creation of the Product Backlog, and how the users experience the involvement. C) An exploration of which information is gathered during the involvement, and how this information is being integrated in the Sprint activities. D) an overview of what areas a high-quality user involvement should address.
After the research was performed, several ideations were made, that were targeting different phases of the user involvement process. These ideas were followed by evaluation sessions with the team members and with the end-users, where the process, the tools needed, the interaction qualities, the steps and the stakeholders were refined.
With all these information, a final design was proposed to AerData: The User Coach for Agile Companies. This process and set of methods comprises all the phases that the company should follow in order to plan and prepare the customer event, gather feedback during the customer event, and analyse the feedback so it can be shared with the end-users and with the development team, until it is finally implemented. The User Coach provides with an explanatory booklet of the process, the templates needed for each phase, and consultation cards that will coach the team members in giving the information needed to achieve the goal of each session. Ultimately, the goal is to allow the team members and end-users to keep track of the feedback and create a connection among them.
In general, the process allows AerData and Agile companies to improve the experience regarding the user involvement, and the relationship with the end-users. Further research should be done regarding the dynamics revolving around the categorized and online feedback, its maintenance and prioritization. A final evaluation should be made in order to understand the relationship among each of the phases and the results obtained with the development activities, and to finally undercover its tangible benefits.","Agile Software Development; User Involvement; Process design; Toolkit; User-centered design; Scrum","en","master thesis","","","","","","","Campus only","","","","","Design for Interaction","",""

In order to become more resilient, organizations need to shift from an efficiency focus to a learning focus. If everyone in an organization or ecosystem learns faster from experiences, the collective performance and innovative capabilities will increase more rapidly. The necessity to learn and personally develop continuously is also recognized by individuals to cope with changing roles and to ensure sustainable employability. Learning Agility (the ability to develop new effective behavior quickly and flexibly based on new experiences) can play an important role in increasing people’s change readiness and innovative behavior. It accelerates learning and gives direction to the development of an individual, by providing insight in his or her learning potential. Fundamental for developing learning agile behavior is Self-Awareness: if you know your strengths and weaknesses, you know where to begin in your development. This is where ReflAction comes in. ReflAction is an application that allows employees to add scores to the activities they engage in that actually contribute to achieving their personal learning goals. A goal is achieved when a self-defined number of positive scores is met, for which also the needed time is kept. Through this simple input, employees can see where they learn from, what they could to do to optimalize their learning and how they progress in their learning goals over time. The organization receives valuable data on e.g. people’s learning preferences, speed and taken approaches to learn a goal, which could enable providing employees with a more personalized learning experience.
By triggering reflection moments to evaluate the learning value of what you do during a day and getting provided insight on where you learn from and how this relates to your progression and performance, people could increase their Self-Awareness and accelerate learning. A Learning Agility profile is established over time through the variety of activities you learn from and the speed in achieving goals. Consequently, by promoting tips, suggestions and micro learnings based on the user’s input data, the organization can not only support people with their learning goals, but moreover evoke explorative behavior and take people out of their comfort zone, in order to experience (and learn) more. Besides a step towards a better intergration of working and learning, the input data indicating learning (agile) behavior could support strategic decision making concerning human capital and retention as well.
Recent research, such as the AGILE project, aims at enabling 3rd generation MDO, where collaboration of distributed teams is key. Maturing MDAO is important to eventually make Overall Aircraft Design possible. However, the industry is still in the early days of 1st generation MDO application.
This thesis proposes a new 1st generation MDO 'pipeline' benefiting from the latest tools developed for 3rd generation MDO. This open-source tool-chain makes it easy to connect analyses and include gradient information. It is shown that gradient inclusion yields dramatically reduced computational costs. Rapid (re)configuration and inclusion of gradient information using this pipeline is demonstrated by considering the Sellar problem and a wing optimization.","MDO; MDAO; Optimization; AGILE; OpenMDAO; Framework; Multidisciplinary; Aircraft; Design; Analysis","en","master thesis","","","","","","","","","","","","Aerospace Engineering","",""

Agile software development teams develop iteration sessions that often last weeks. During development, teams work on technical code and its content. Intuitively, more effort is required to implement new features in poorly constructed code with low quality. This study investigates if and how developers consider the quality of their code during their agile effort estimations. Furthermore, we investigate whether the accuracy of their estimations could increase if developers considered the quality of the code. This study is conducted in a large software development department, that is part of Royal Dutch Shell. We take a mixed method approach, where we interview nine developers and quality experts and mine the repositories of six agile development teams. Initially, we reviewed the existing importance measures of code quality during effort estimations, including how code quality is maintained. We also evaluate the impact of code quality on estimation accuracy.
Developers did not consider code quality high on the priority list during the estimation stage of development. Similarly, we did not find an empirical relationship between the quality metrics and effort estimations. Surprisingly, code quality only had minor effects on the accuracy of the effort estimations. Developers did often encounter quality issues in legacy code. However, overall our study shows that code quality is only of minor importance during agile effort estimations.
This graduation project was carried out together with Barco with the intention to unlock the innovation potential of its employees by creating a solid foundation for DLA. To do so, a thorough qualitative research was carried out to discern the challenges Barco faces, its current process structure and an optimal way to develop design capabilities. These aided the design of a new solution that will help Barco reach the state of a well-orchestrated innovation flow supported by employees who share the same mental model and level of capabilities.","design-led ambidexterity; Ambidexterity; co-design; innovation infrastructures; design capabilities; way of working; Agile; organizational design","en","master thesis","","","","","","","Campus only","","","","","Strategic Product Design","",""

During this research a collaborative environment is developed and implemented to provide a steering function during the setup of 3rd generation MDO frameworks.

The resulting collaborative environment contains user-interfaces and automated services which support in the formulation of MDO processes, inspection of design study results, management of design case requirements and integration of disciplinary analysis modules.
Based on the work performed in this research, it can be concluded that the developed collaborative environment shortens the design process lead-time.

Though the agile practices have gained widespread popularity in the recent years, there are quite a number of concerns in scaling the agile practices from team level to the entire enterprise. Few frameworks such as Scaled Agile Framework (SAFe, Disciplined Agile Delivery (DAD) and Large Scale Scrum (LeSS) have been developed to address these concerns in scaling agile practices. Although these frameworks provide a template in scaling agile in large enterprises, currently there is a lack of a holistic method which would help them in implementing scaled agile practices or adapting to scaled agile software development. Before or after adopting such a framework, organizations require a structured model for assessing the level of completeness of adoption or find areas of improvements in the scaled agile practices, which would also help them in developing a roadmap for further progress and initiatives. This research offer guidance for the IT organizations towards scaled agile software development by providing a maturity model. This maturity model is composed of six stages as rows and five scaled agile principles in columns, in which each stage and column forms a matrix of scaled agile practices. Each of the practices consists of indicators which help in assessing the level of adoption of the practices. Once having identified the lacking criteria in the adoption of scaled agile practices, organizations can start focusing on the lacking criteria and other areas of improvement. The research also strongly suggests the collaborative spirit in adaptation of scaled agile practices, by using this model as a discussion tool in the team, program and portfolio levels of scaled agile environment. Future research in this arena would aim at researching on the dynamics of emergence on scaled agile practices and the notion of such an emergence on multitude of stakeholders involved in a scaled agile process.","scaled agile framework; agile software development; maturity model; scaled agile practices; ambidexterity","en","master thesis","","","","","","","","2017-08-17","Technology, Policy and Management","System engineering policy analysis and management","","","",""

(mentor); Calabretta, G. (mentor)","2016","The FinancialServices(FS) industry of advisory is inter- ested in the agile methodology and its practices. There are two reasons for this interest: first of all their clients, banks, are interested in these methods for their process management. Second, in order to keep up with the competition they need be up to date with new methods and knowledge. The assignment was to look for inter- esting applications of the agile philosophy within FS advi- sory. Advisory X has two main activities: client projects and internal projects. Through an interaction analysis of interviews is found that internal projects are not agile at all. The internal project interactions show that there is a lack of cross competency collaboration, lack of transparent commu- nication from partners to consultants, an individual mindset and a lack of overview. Moreover there is little attention for internal projects, because of the strong focus on direct profitability of client projects. This focus on client work is enforced by the current evaluation system, where mainly is looked at the percentage that consultants spent working for a client. A look into the working hours of FS consultants showed that 46% of their time was spent on client projects, leaving 54% for other activities than client work (from July-December 2015, for FS advisory). The 46% spent on client projects does not come near the aimed goal that consultants spent 70% of their time working for a client. There is no insight or overview on the activities performed in this other 54%. This shows a large opportunity for agile management of internal projects, as time in between client projects is short and tasks need to be done in small sprints. A transparent overview will contribute to insight and grip on these hours. Furthermore cross competency collab- oration and working in dedicated teams will benefit the productivity and quality of hours spent on internal projects. To create insight in these activities, this project has first defined an ideal future scenario. After this a tool was designed to facilitate agile management of internal projects. The future scenario relies on the creation of an internal scoring system with so called “internal project points”. These points can be earned when finishing internal projects within a small team of consultants. These points can be exchanged for learning and development train- ings. This facilitates a dedicated team environment, where consultants work cross competency, where communi- cation between partners and consultants is transparent and where there is an overview on internal projects. The tool facilitates the future scenario and is partly based on existing agile tools, as encountered in the liter- ature review and interviews. It exists out of two parts: an internal project board and a virtual team board. The first is a physical board that provides an overview of all internal projects in FS advisory. The latter is a virtual team board, a team app, that provides overview of ongoing activities and connects team members any place, any time. These tools are openly available for any FS consultant to stimulate transparent communication. Furthermore there is a plan proposed for the implemen- tation and recommendations are made for the tool. The tool is prototyped in the form of a whiteboard including instructions for the use of the board. Moreover there was a pilot set up with consultants involved in the current block chain initiatives to take the first step in using the internal project board. The concept of internal project points will be continued with the advice of testing in small steps, in order to iterate quickly. The goal of this tool is to provide a stepping stone for agile management of internal projects. Another goal is that the tool facilitates and sparks the discussion about the value of internal projects within FS advisory X. The concept of internal project points helps to create insight into the lost 54% of consultants time. It manages consultants time more effectively by providing a stimu- lating team environment, where there is a clear focus, even across competency. The consultants are being valued and noticed for all their hard work at advisory X, including internal projects.","agile; advisory; design; tool; internal projects","en","master thesis","","","","","","","Campus only","","Industrial Design Engineering","Product Innovation Management","","Master of Science Strategic Product Design","",""

(mentor); Pasman, G.J. (mentor); Van Kuijk, J.I. (mentor)","2013","Problem Statement The most standard used process for developing software is currently Agile. Agile splits up the design process in so called two week “sprints” thereby making this process fast and efficient for developers. But current methods of usertesting don’t fit with this fast-paced process as, they are time consuming and too extensive. Therefore results from the user tests become mostly “out-dated” and irrelevant for teams. The same was the case at IceMobile, which is Holland’s largest mobile application producer, who developed award winning applications such as the Albert Heijn and the ABN AMBRO application. IceMobile shifted from an agency model to developing own products for the retail sector, making IceMobile responsible for the quality of the user experience (UX) of their products. Having a usertesting process that fitted with their Agile process became important An empirical study was performed with two product teams, which showed developers having little knowledge about and empathy for their users. Result My proposal for IceMobile are the Flags sessions, containing a frequent process where the teams of IceMobile collaboratively analyse and evaluate the feedback of the user, by watching the interview of the UXlab via a live stream connection. With an effective way of clustering all insights and a fast interview process, the whole session only takes 1,5 hour over two days for the whole team. By frequently conducting flag sessions every sprint, the team builds up knowledge, creates more empathy, which makes results become more reliable. The sessions are flexible and take minimum amount of time, making them fit well with the Agile process of IceMobile. The Flag sessions will involve the team in the usertests, thereby reducing the time of the usertesting process while increasing empathy for the user by the team. Therefore the team comes out of the sessions with more inspiration and motivation to change or develop new features for the user.","Agile; UX; software; usertesting; usertest; developers; app; mobile; research; Scrum; user experience; empathy","en","master thesis","","","","","","","Campus only","","Industrial Design Engineering","Design for Interaction","","Final Master Project","",""

Combining these however creates an interesting paradox. Where agile clearly states that documentation is not the most important thing, from the field of globally distributed engineering a higher focus on documentation is observed. In this thesis the field of requirements engineering is also taken into the mix. Combining these three a user-story model is defined to take advantage of the, on first sight, downside of working distributed. The fact that face-to-face communication is not possible means that all the communication has to be done using technological support and thus that this communication can be saved. This premise gives an interesting opportunity to keep track of the actions that are taken on user-stories as a result of a conversation. By saving the conversation and coupling the action to parts of that conversation.","agile; requirements; user-stories; distributed; requirements engineering","en","master thesis","","","","","","","","2012-12-08","Electrical Engineering, Mathematics and Computer Science","Computer Science","","Software Engineering","",""

(mentor)","2012","In today’s highly competitive environment, it becomes increasingly common for many companies to face internal and external pressure for delivering their products and services with the lowest cost and/or fastest time possible. Information Technology Outsourcing (ITO) has helped to release part of such pressure by enabling companies to gain cost advantage and obtain access to qualified labor pools (Manning, Massini, & Lewin, 2008). Not too far from this topic is Agile Software Methodologies, which came into place by promoting continuous releases and close customer participation along the software development process. Agile Scrum has been defined as the most mature and widely adopted method from all the Agile methodologies (Hossain, Babar, & Paik, 2009). Further investigations suggest that Agile Scrum, in collocated development, can increase productivity up to 5-10 times higher than the industry average and empirical evidence proposes that non-collocated teams can reach the same performance (Sutherland, Schoonheim, & Rijk, 2008). Blending Offshoring Outsourcing projects with Agile Scrum, seem to be the perfect combination for many companies. However, companies continue facing difficulties in reaching such promised results and the mechanisms behind the ability of Agile Offshoring Outsourcing to shorten time-to-market remain hazy. Investigations explaining why certain projects cannot reach such promising results are scarce. This problem context led us to the main research question: What criteria hinder the reduction of time-to-market in software development projects that combine Agile Scrum with Offshoring Outsourcing? To answer it, we first researched what is Agile Scrum and how software development takes place under this methodology. Our research revealed that Agile Scrum is conformed by three main actors: ScrumMaster, Product Owner, Development Team. Additionally, literature suggests that Scrum demands high levels of interaction, openness and flexibility among all its participants. The second step in our research was to understand on how Offshore Outsource project are executed through their most common problems. Literatures addressed us into five main topics: 1) Culture Differences – subdivided into National Culture and Organizational Culture, 2) Coordination, 3) Trust, 4) Time Zone Differences and 5) Effective Communication. Based on these theoretical concepts we built a Conceptual Model containing twelve propositions describing what criteria influence the reduction of time-to-market. Each proposition is associated to Scrum concepts and how they could stimulate or hinder the reduction of time-to-market based on the context where the project takes place. Following, we conducted a multiple case study considering a Belgium telecommunication company (the Client) and an Indian outsourcing service provider (the Vendor). The unit of analysis: projects blending Outsourcing Offshoring and Agile Scrum. The Case Study analyzed two projects: 1) Red Project. The project suffered major delays on the original schedule, thus the Vendor decided to introduce Agile Scrum to reduce such project gap. The project delivered part of its functionality and later it was halted. It is considered a major failure in their Client-Vendor relationship. 2) Blue Project. Second project in timeline. Agile Scrum practices were also introduced after the project was already started through a Vendor initiative. The project experiences neither major delays nor exceptional performance, however Client-Vendor frictions were found in the meantime. The refined Conceptual Model is described in Figure 6 7, page 78. Our findings can be summarized as: 1)The Identification of criteria influencing the reduction of time-to-market: Literature deductions supported by empirical evidence suggest the existence of at six criteria influencing the reduction of time-to-market. Such criteria is expressed in six prepositions the mentioned Conceptual Model (P1,P3,P5,P7,P9,11). 2) Implicit evolution of the Agile Scrum methodology. No scientific evidence was found tracking the implicit simplification of Scrum as a methodology, confirming the gap between practitioners and scientists with regards Agile practices. Additionally, based on the theoretical findings and empirical experience from the Case Study, we derived a set of recommendations to Clients and Vendors aiming to reduce time-to-market while conducting this type of projects. For further research, we recommend the following topics: 1) Complement the current research quantitative research techniques and also conduct case studies in other industries besides telecommunication 2) Investigate the most suitable contract agreements in Agile Scrum Offshore Outsource Projects. 3) The execution of Agile Scrum Offshore Outsource Projects involving multiple organizations and 4) Research on why Agile Scrum certifications are largely concentrated in western countries.","Agile Scrum; Offshoring Outsourcing Software; time-to-market; qualitative research; multiple case-study","en","master thesis","","","","","","","Campus only","","Technology, Policy and Management","Management of Technology","","","",""

(mentor)","2011","Roomplug was founded to make renting simple. It provides all the tools needed to go from having an empty property to getting the lease agreement signed. Roomplug also wants to solve the problems on rent payment. That is what this project is all about: creating an online rent payment system. Since Roomplug is a startup company, it is expected that the requirements will change as the business model and needs of Roomplug change over time. The Feature Driven Development (FDD) methodology was chosen to create a development track suitable for this changing set of requirements. In the FDD track, the features are split up and grouped in milestones. Every next milestone can be changed to support the (new) needs of Roomplug. Before work on the first milestone starts, a global high-level design is created to make sure that all milestones work towards the same goal. The design details of each milestone are then created as soon as work on that milestone starts. This prevents unnecessary design work on features that will never be implemented. Implementation starts after the milestones design is ready. The Roomplug back-end system, and thus the payment system, is written in PHP using Zend Framework and its MVC pattern. It uses a MySQL database to store all the data. Testing the code after the implementation of a milestone is a big part of the project. Many test classes are written to ensure the correct functioning of the payment system. PHPUnit generates extensive coverage reports after each test run. All this is very use full to ensure that code from earlier milestones still works after making changes and additions to implement the next milestone. The finished prototype of the payment system lets users create single custom payments and set up recurring payments using PayPal as a payment method. Although an account is needed to receive payments, paying your rent can also be done as a guest without an account. The system is designed in such a way that other payment systems could easily be added in the future. The payment system is currently running live on the Roomplug beta site. It is ready to be used by the rental market.","PayPal; Rentals; Zend; PHPUnit; Agile; Feature Driven Development","en","bachelor thesis","","","","","","","","","Electrical Engineering, Mathematics and Computer Science","Software Technology","","","",""

Companies look for agility in their business for flexibility and adaptation with respect to changing environments. They seek to make use of the market competencies and deliver customer-centric services to gain the competitive advantage by providing a one-stop mall where customers can experience several kinds of integrated services. With the opportunity of Integrated Service Delivery (ISD), companies can support clients in an integrated environment possibly reducing cost and time. Doing so, service providers face a number of challenges related to organizational integration, resistance towards change and being customer-centric. With a structured process, collaboration and coordination of activities in ISD can be efficient, reducing the complexities in those challenges. Research has shown adoption of Agile methodologies has reduced complexities in software development and focused on collaboration and coordination to achieve performance gain. Therefore, in this case, adopting Agile management principles will be highly beneficial in ISD. To the best of our knowledge there has not been research on how to manage the service lifecycle of ISD in a holistic view and focus on the collaboration of parties involved in the process and coordination of activities, by working in an Agile approach. Therefore, the main research question of this research is: ""How can Agile management and service development principles be incorporated together for effective collaboration between parties and coordination of activities in Integrated Service Delivery?"" Following a design science research methodology and case study research, this research was conducted to develop a conceptual process model, namely Agile Process for Integrated Service Delivery (APISD), which was evaluated by three cases conducted in three organizations. From the case study findings, the APISD model was enhanced. Furthermore, an illustration of APISD was given to materialize the model in practice.","Agile Methodology; Integrated Service Delivery; Scrum; Process","en","master thesis","","","","","","","","","Technology, Policy and Management","Management of Technology","","Information and Communication Technology","",""

The Voltea Case","Soilemezidis, K.S.","Scholten, V.S. (mentor)","2011","The main topic of this thesis is the business strategy of new Corporate Ventures, the so-called in our research Market Entry Strategy. We tried to find out how the Corporate Ventures formulate and implement the business strategy to enter new markets. The phenomenon of Corporate Venturing, the differences of Corporate and Independent Ventures, the factors that influence the strategy formulation process, the role of the parent organization in the stategy formulation and venture development in general, are the research questions we adressed during this study. We had the chance to observe the strategy formulation process in person by conducting an internship in Voltea's premises, a new venture owned mainly by Unilever. Voltea is developing a desalination technology, the Flow-through-Capacitor (FTC) techology, and currently is looking for commercial applications in order to enter into the market. We examined two markets and tried to formulate the optimal strategy based on a model we developed that assesses the market attractiveness, the corporate venture and the parent organization, namely the analysis of the resources and the skills that venture managers have at their disposal. Furthermore, it is analyzed the CEO personality and the corporate fit of the new venture with the parent organization, i.e. the operational relatedness and the strategic significance. We ended up with useful conclusions about the way corporate ventures operate and formulate their strategy. Undoubtedly, the most significant finding of this research is that business strategy for new corporate ventures should not be the first priority. On contrary, it is the structure and the organization of the new venture that has to be flexible and agile, that will lead the venture to the path of success.","corporate ventures; market entry strategy; flexibility and agility","en","master thesis","","","","","","","Campus only","","Technology, Policy and Management","Management","","MSc Management of Technology/Technology, Strategy & Entrepreneurship","",""

(mentor); Jacobsson, M. (mentor); Niemegeers, I. (mentor)","2009","Based on IEEE 802.15.4, ZigBee is developed for low-power and low-data-rate wireless communication and it is building up remarkable position for wireless sensor network (WSN). As ZigBee is using the 2.4GHz Industrial, Scientific, and Medical (ISM) unlicensed frequency band, coexistence issues arise as there are also other wireless technologies sharing the same band, such as 802.11b/g WiFi, Bluetooth, cordless phones and even microwave ovens. Due to the low transmission power, ZigBee is potentially vulnerable to the interference introduced by these technologies rather than vice versa. Therefore, it is desirable to improve the robustness of ZigBee networks. As WiFi is widely deployed and often collocated with ZigBee networks in applications, such as hospitals and home buildings, we take WiFi as the main interference source and work on finding solutions to enhance the robustness of ZigBee networks under WiFi as well as other interferences. To improve the robustness of ZigBee networks, a feature called frequency agility is specified in the ZigBee standard. We found, however, some inadequacies in the standard that needs to be improved before the frequency agility can function well in practice as it is supposed to do. A better periodical window method is proposed to improve the detection time to interference. Besides, in case that there is only a part of the whole network suffering from some local interference, it is neither necessary for the whole network to move to a new idle channel because this movement is costly and risky, nor possible to find an idle channel for the whole network to move to. Therefore, we extend the frequency agility function by enabling a single ZigBee network to work on multiple channels. As some local interference appears, the part of the network which is under the interference can move to a new idle channel while maintaining the communication links with the other part of the network which stays on the original channel and the moved part can move back to the original channel when the interference disappears. OPNET simulations shows that our multi-channel solution can significantly improve the robustness of ZigBee networks in a cost-efficient way.","ZigBee; coexistence; multi-channel; frequency agility","en","master thesis","","","","","","","","2009-08-29","Electrical Engineering, Mathematics and Computer Science","Telecommunications","","","",""

The current trend is that increasingly more organizations develop their software in a globally distributed setting. Although SAFe is being deployed in such a setting, SAFe was not originally developed for such a setting but for a co-located setting. Therefore, this research investigates the application of SAFe in globally distributed settings. Five problems are discovered that can be expected to fail when SAFe is applied in distributed settings: incorrect execution of SAFe, language barriers, time zone differences, increased communication effort, and inefficient communication tools. Given these problems, four SAFe elements are identified that can be expected to fail when SAFe is applied in distributed settings: the PI planning, the inspect & adapt meeting, the DevOps team, and the system team. Finally, a customization of SAFe for distributed settings is proposed. This customization is focused on solving the discovered problems for the elements identified to fail.","Scaled Agile Framework; SAFe; Agile Release Train; distributed; Distributed Agile Development","en","master thesis","","","","","","","","","Electrical Engineering, Mathematics and Computer Science","Software Technology","","Information Architecture track","",""
