This book introduces readers to a variety of aspects in the field of Organization Development (OD), from conceptual, theoretical ideas to the research upon which these are based. It is exemplified by original case studies and supported by the educational process to develop competent OD professionals in these areas. Experienced educator and professor Marilyn Laiken begins by examining key concepts and approaches in OD, focusing on contextual issues – from an individual professional’s realization that organizational systems shape their effectiveness, to the diverse environments in which practitioners operate, and the types of interventions typically involved. The discussion then highlights the critical role of original research in bridging theory and practice, showcasing how organizational learning, interprofessional collaboration, and high-performance team development can drive meaningful organizational change. This book also demonstrates the practical application of theory through real world case studies, each drawn from a unique context that illustrates the concepts in action. Building on two decades of teaching experience, the author then turns to the preparation of skilled OD professionals, reflecting on effective educational methods. Shedding light on past research and emerging trends, this book considers how the field of Organization Development will continue to evolve and influence the future of work.
