A new member of the renowned PH OD Series! The main purpose of this book is to help managers, change agents, and scholars to understand, diagnose, and facilitate the change of an organization’s culture in order to enhance its effectiveness. Diagnosing and Changing Organizational Culture presents three forms of assistance: (1) validated instruments for diagnosing organizational culture and management competency, (2) a theoretical framework for understanding organizational culture, and (3) a systematic strategy and methodology for changing organizational culture and personal behavior. It is intended to be a workbook in the sense that an individual can complete the instruments and plot their own culture profile in the book itself, and use it as a resource for leading a culture change process.
