PrefaceWith this preface, I first introduce how this thesis came into being. Secondly, I acknowledge the people who supported and influenced me during the four years of my research on niche-innovations.A bit more than four years ago, a day before I defended my master thesis on corporate diversification strategies at Tilburg University, I received an e-mail from my supervisor asking me if I would be interested in doing a PhD at the University of Twente. Five days later, it was December 23 rd 2009, a day before Christmas, Iwas sitting in Geert Dewulf's office, talking about the PhD trajectory for two and a half hours. The research project was about developing strategies in a nicheinnovation project that primarily concerned the cooperation of two long-term care organizations. It was subsidized by a transition program that aimed at changing the long-term care system. I was very interested in the topic as I saw a good opportunity to continue my research on strategy development. Yet in a new domain: long-term care. As it felt like the right time, the right place and the right people, I started my research in January 2010. Initially, being a fresh graduate who was boosted with pure confidence, I was keen to support the strategy development in the project. Throughout the four years, however, I learned that there are all kinds of barriers hindering the development of strategies for niche-innovations which show that the long-term care system has not been ready for change.While the project was running smoothly throughout 2010, it abruptly ended shortly after the subsidy ended in 2011. Hence, I had to look for other cases to develop strategies out of niche-innovations. I wrote a proposal that outlined how the lessons learned in the original project could be used in a new project. One of the participating long-term care organizations of the original project accepted the proposal in 2012. I started conducting interviews as well as holding a workshop to form new strategies out of niche-innovations. But half a year later, the project was cancelled due to an organizational restructuring. I was asked to use the insights in the previous project to re-write the proposal in order to develop integrated longterm care strategies. In 2013, I conducted another 20 interviews. But also this project was cancelled after my key contact person was fired. In the meantime, I integrated my ideas about strategy development in a proposal that we (Geert Dewulf, Hans Voordijk and I) wrote with researchers from Germany and Norway for the Framework Programme 7 (FP7) of the European Union. Unfortunately, our proposal scored just below the threshold. As a consequence of all these drawbacks, vi I started to refocus my research to highlight the importance of understanding the barriers to change so that future programs can enable the change of the long-term care system. In so doing, I used the data of the original project, and data from a retrospective study on two other niche-innovation projects that also participated in the transition program.Writing a th...
