Book excerpt: The third book in this series is written by a team of interdisciplinary teachers and professionals, led by Mike Waterhouse and Geoff Crook, is aimed at students and professionals in the built environment who wish to develop their management and business skills. In a rapidly changing world where techniques and custom and practice can date soon after discovery, where organisations are constantly changing shape and style to cope with rapid technological, economic, political and social change, there is a need for managers and built environment professionals who know how to learn, who are self-aware enough to know when they don't know, and who have the confidence and personal substance to be able to initiate the required learning activites when necessary.
