In many entrepreneurial projects, the concept of the business model (BM) is used to describe a business idea at a high-level and in a holistic way. However, existing literature pays less attention to implementation (or execution) of BM. Implementation becomes more complex when a BM is proposed by or requires a network of collaborating enterprises. The aim of this paper is to provide an approach based on empirical research that supports BM transition from design to implementation. The empirical data used in this paper is based on a case study involving an innovative project in the pharmaceutical sector in Finland. The case analysis demonstrates how a high-level BM needs careful consideration of its operational components from a network perspective to secure both value creation and capture. Drawing on the analysis, six concluding propositions on BM implementation in networked settings are put forward.@en

The need for sustainable built environment is pressing; an urgency that spans environmental, economic and social values of sustainability. Since late 1980s, the Lean philosophy has been adopted in the construction sector, with a focus on efficiency, predominantly as a function of economic competence. More recently, however, the Lean principles and practices have been revisited and increasingly used to create and preserve social and environmental values as well. The result was a growing, but dispersed, body of knowledge on sustainability and Lean construction, and hence, equivocal about how Lean contributes to sustainability. By means of a Systematic Literature Review (SLR) based on 118 journal articles from 1998 to 2017, this article aims to provide a comprehensive understanding of “how Lean helps achieve and maintain sustainability in construction sector”. The findings are structured into a holistic framework, which underlines a multidimensional approach toward sustainability, i.e., focus on stakeholders, across various construction phases, while simultaneously being heedful of concerns regarding people, planet, and profit. It became clear that the current body of knowledge is mainly skewed toward economic values, which calls for more research in the social and environmental aspects of construction. This study assembles a palette of existing best practices, based on which scholars’ and practitioners’ can balance their efforts across three dimensions of sustainability. Moreover, it identifies several under-researched areas of Lean sustainable construction that have the potential to be expanded in by future researchers.@en
