Using Gamification to Address Technical Debt: A Case Study at Adyen

Technical debt is a term that describes the consequences of taking shortcuts or quick-and-dirty solutions in the software engineering process, in order to gain short term advantages in the development process of software projects. In this paper, we investigate the technical debt present at the fintech company Adyen, and the developers'...

Assessing maintained bed levels in ports

The accessibility of a port, which is mainly determined by the available water depth, is of economic importance for a port to distinguish itself from other ports. For the vertical design of navigation channels, the goal is to make routes equally accessible and not have bottlenecks; to have an optimal maintenance program and not incur unnecessary...

The Delta Maintainability Model: Measuring Maintainability of Fine-Grained Code Changes

Existing maintainability models are used to identify technical debt of software systems. Targeting entire codebases, such models lack the ability to determine shortcomings of smaller, fine-grained changes. This paper proposes a new maintainability model – the Delta Maintainability Model (DMM) – to measure fine-grained code changes, such as...

Redesign of the Solution Algorithms in Wanda

The Wanda software package developed by Deltares can used for simulating both steady state and transient fluid flow in pipeline systems. Steady state simulations are used for initial system design and transient flow simulations are used for doing water hammer analysis in pipeline systems. For both types of simulations a system consisting of both...

Classifying code comments in Java Mobile Applications

Developers adopt code comments for different reasons such as document source codes or change program flows. Due to a variety of use scenarios, code comments may impact on readability and maintainability. In this study, we investigate how developers of 5 open-source mobile applications use code comments to document<br/>their projects....

Integrated project delivery methods for energy renovation of social housing

European Social Housing Organisations (SHOs) are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer...

Automated detection of test fixture strategies and smells

Paper accepted for publication in the Proceedings of the Sixth International Conference on Software Testing, Verification and Validation, IEEE Computer Society, 18-22 March 2013, ISBN 978-1-4673-5961-0, doi: 10.1109/ICST.2013.45 Designing automated tests is a challenging task. One important concern is how to design test fixtures, i.e. code that...

The Impact of Antipatterns on the Change-Proneness of Java Systems

We replicated a part of the recent study on the impact of design defects on the change-proneness of software applications and extended it by performing an analysis based on ?ne-grained source code changes (SCCs) performed on Java classes during the evolution of the systems. Using SCCs extracted from the version control systems of 16 Java open-...

Faster issue resolution with higher technical quality of software

We performed an empirical study of the relation between technical quality of software products and the issue resolution performance of their maintainers. In particular, we tested the hypothesis that ratings for source code maintainability, as employed by the Software Improvement Group (SIG) quality model, are correlated with ratings for issue...

Faster Defect Resolution with Higher Technical Quality of Software

We performed an empirical study of the relation between technical quality of software products and the defect resolution performance of their maintainers. In particular, we tested the hypothesis that ratings for source code maintainability, as employed by the SIG quality model, are correlated with ratings for defect resolution speed. This study...

The In?uence of Software Maintainability on Issue Handling

Ensuring maintainability is an important aspect of the software development cycle. Maintainable software will be easier to understand and change correctly. The Software Improvement Group (SIG) has developed a method to measure a software system's maintainability based on well-known code metrics. In this thesis we explore the relationships...
