Michael Marti presents a complexity management model that is based on the reasoning that product architecture determines to a considerable extent how external complexity is translated into physical products. The model demonstrates a procedure to optimize a products architecture and is applied to several industrial products.The discussion about increased product complexity in Western European companies has been omnipresent for decades. This is due to ever new demands (real or c- ceived) from the market and new possibilities (technical and others) open to the p- viders of products and services to come up fast with very specific solutions. The m- agement of this complexity inside the company so as to achieve a balance between the market benefits of more customer specific solutions and the internal costs induced by this is still a big challenge. After years of research in this area there is still a lack of tools to help practitioners to take decisions about the right degree of complexity for a product or the right design of a product architecture. Mr. Marti brings together three perspectives on this topic in an easily understa- able and communicable way: The strategy of the company (combined with the mat- ity of the product), the functionality, and the physical complexity on a component level. The visualization in a complexity matrix is an important new tool especially for fostering the understanding for complexity issues in a company! With this book Mr. Marti has come up with an outstanding contribution to product complexity management, which is crucial for the future competitiveness of companies in Western Europe. I hope that this book will find a broad distribution as well in pr- tice as in theory for the sake of our countries!
