In 2007 Professor Werner Pfeiffer, the doyen of German innovation and technology management, celebrated his 75th birthday. His most well-known works are the “Allgemeine Theorie der technischen Entwicklung als Grundlage einer Planung und Prognose des technischen Fortschritts” (“General theory of technological development as the basis for planning and predicting technological progress”), Göttingen 1971, and the “Technologie-Portfolio zum Management strategischer Zukunftsgeschäftsfelder” (“Technology portfolio for the management of strategic future business areas”), Göttingen 1982, which he co-authored with G. Metze, W. Schneider and R. Amler. His two students, a grandson and a follower of the “Pfeiffer School”, wanted through this book, “Innovation profitability analysis”, to write a new chapter in innovation research
