I remember clearly my parents' advice when, like all teenagers, I wondered what I would do when I grew up. They said, "Money is not important. It will never bring you happiness. [Strange advice to a future economist.] Use the brain God has given you, and be of service to others. That is what will give you satisfaction"." Joseph E. STIGLITZ, 2010: p. 276 Recipient of "The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel 2001" I would like to express my highest gratitude towards my supervisor Prof. Dr. Marco W. Groll. He ventured to accept me as a PhD student and I am deeply grateful for this opportunity. I highly appreciate the scientific freedom I was granted, fruitful discussions, with valuable input, helpful limitations in scope at the given time, and organizational support in this new phase for me. Without Prof. Dr. Groll's guidance, this thesis would not have been feasible. Furthermore, I would like to thank my supervisor Prof. Dr. Jörg Henseler for his structured comprehension and scientific rigor which helped me to ameliorate this thesis as well as driving the official process. I also would like to extend my appreciation towards the members of the graduation committee dr.ir. Gerrit Maarten Bonnema, Prof. Dr.-Ing. Roman Dumitrescu, prof.dr. Ian Gibson, prof.dr.ir. H.F.J.M. Koopman, Prof. Dr. Josef Oehmen, for their valuable input, participation in the defense ceremony, and support. I am exceptionally beholden to my internal supervisor at Daimler. Dr. Axel Lankenau, the team leader of E/E documentation and testing, who supported me scientifically, encouraged publications, served as enabler where necessary, gave me space, and helped me to focus where required. With his brilliance and yet nonchalance, respect, and motivation to others, Dr. Lankenau defines the embodiment of an excellent leader for me. Dr. Frank Arbes, head of the department of CoC electrics/electronics & software, IT processes & methods at Daimler, I am very grateful not only for his monetary support during my PhD phase at his department, but also for his encouragement during rough patches. I am much obliged that he gave me the opportunity for this endeavor, to be able to learn and grow as part of this PhD. Prof. Alfred Katzenbach I am thankful for the introduction of me to Daimler and for shaping the beginning of my work. I appreciate Dr. Siegmar Haasis', CIO R&D Mercedes-Benz Cars, PhD-friendly environment and that I had the chance to combine research and application in his center.
