How can organizations handle the opportunities and threats posed by rapidly changing markets and external conditions? How can they improve their overall effectiveness? The Second Edition of this popular book contains up-to-date treatments of techniques and models for diagnosing how organizations deal with challenges like these. The book also shows how consultants and applied researchers can help managers find ways to enhance organizational effectiveness. Completely revised, this edition: presents the most recent techniques for gathering and analyzing diagnostic data; covers models and methods for diagnosing organizational designs, everyday practices, fits among organizational components, organizational politics and power relations; and explores the ethical and political dilemmas of consulting and diagnosis. The book retains its original coverage of the process of working with members of a client organization to plan and administer a diagnostic study and communicate its results. It also continues to focus on group processes and the quality of working life.
