Acknowledgments
The present work “A Methodology for the Identification of Technology Indica-
tors” presents my research work at the Heinz Nixdorf Institute, University of
Paderborn. It summarizes the working experience and the research results that I
gained from the research areas of technology planning and product innovation
in several research projects.
First of all, I would like to cordially thank Prof. Dr.-Ing. Jürgen Gausemeier for
giving me the chance to do my PhD and also for his patient instruction as well
as support.
I greatly appreciate the co-supervisorship and advice of Prof. Dr.-Ing. Jörg
Wallaschek and Prof. Dr. Wilhelm Schäfer. I am also grateful to Prof. Dr.-Ing.
Ansgar Trächtler as the chairman of the board of examiners.
I am also thankful to the International Graduate School Dynamic Intelligent
Systems at the University of Paderborn for offering the professional, financial
and intercultural support in the three years of my PhD.
Regarding my work, I would like to give the very special thanks to my team
leader Dipl.-Wirt. Ing. Christoph Wenzelmann, who has always provided me
useful assistance and is obliging to impart me his experience and knowhow.
Great thanks should also be forwarded to Dipl.-Wirt. Ing. Stephan Ihmels,
Dipl.-Wirt. Ing. Karsten Stoll and M. Sc. Chengyee Low.
I would also like to thank all other current and former members of the team of
Innovation Management for having shared a very intense time and for the
brilliant teamwork experience: Dr.-Ing. Daniel Steffen, Dr.-Ing. Jan Stefan

Vienenkötter, Dipl.-Wirt. Ing. Ingo Kaiser, Dipl.-Wirt.-Ing. Volker Brink,

secretaries: Ms. Sabine Illigen and Ms. Alexandra Dutschke; to our “computer
guardians”: Dipl.-Ing. Karsten Mette and his apprentices; as well as to my nice
workmate and also my last roommate Dr.-Ing. Salvatore Parisi for his great
support.
Last but not least, my sincere thanks to my boyfriend Shan He for all his sup-
port and patience; to my family for showing me the way of life and always
being there; to family Gausemeier for their ungrudging help and care.
