In this book, leading experts in design methodology, most of them active in the Design Society, reflect the great progress that has been made, but also identify the challenges of future development of the topic.

The reason that this book has been compiled was the retirement of Professor Herbert Birkhofer in 2011 after a long and distinguished career. Among other things, Prof. Birkhofer was the founding President of the Design Society and, since 2009, is a Honorary Fellow of the Society.
