To my network v Acknowledgements This is the place where soon-to-be PhDs look back on their experiences. It is usually rife with clever metaphors and sentimentality. So you are forewarned... Getting a PhD is like going on a road trip by car. The destination is clear but the journey there is not. In fact, the roads and terrains change frequently. Prof. Peter Vervest was the co-reader of my master thesis and after the defense he encouraged me to pursue a PhD. I am indebted to him for inspiring me and opening (car) doors. Throughout the journey, Peter's habit of thinking in an expansive manner often felt like he wanted the car to venture into space. While I never quite saw my car as a spaceship, this "thinking big" did provide me with novel perspectives on the journey. During the last stage Peter showed me how he can get down to the nitty gritty too, in terms of feedback, which I also appreciated. Prof. Eric van Heck watched my journey more closely as on-site promoter. Eric's support is thankfully appreciated as well as his thoughts and critical questions to help further the work. Eric tests his PhD students and when he hears convincing arguments he will gladly give the green light to continue. I highly commend him for that. Moreover, Eric dedicated more time in his schedule to pick up the speed during the last leg of my trip. I have been glad to see him around the department and to always be able to discuss matters with him.

These cases denote the transformation of organizations into networks while in other industries and sectors such as construction, public management and health care, networks continue to exist as traditional forms of organization (
