The overall structure of this edition is the same as in the past. The book moves from the smaller to the larger. We start with the individual as the focal unit, move to two-person relationships, and onward to issues of leadership, power, small groups, and whole organizations.This edition focuses more than ever on the managing process—on whole organizations and on managing relationships with other organizations. To underline that emphasis, we have included a new section called 'The Manager's Job.' That section deals with what managers do, how they do it, why they do it, and how they should do it.
