Organization development (OD) is the study of successful organizational change and performance. OD emerged from human relations studies in the 1930s, during which psychologists realized that organizational structures and processes influence worker behavior and motivation. More recently, work on OD has expanded to focus on aligning organizations with their rapidly changing and complex environments through organizational learning, knowledge management and transformation of organizational norms and values. Key concepts of OD theory include: organizational climate (the mood or unique “personality” of an organization, which includes attitudes and beliefs that influence members’ collective behavior), organizational culture (the deeply-seated norms, values and behaviors that members share) and organizational strategies (how an organization identifies problems, plans action, negotiates change and evaluates progress).
Organization development is an ongoing, systematic process of implementing effective organizational change. OD is known as both a field of science focused on understanding and managing organizational change and as a field of scientific study and inquiry. It is interdisciplinary in nature and draws on sociology, psychology, particularly industrial and organizational psychology, and theories of motivation, learning, and personality. Although behavioral science has provided the basic foundation for the study and practice of OD, new and emerging fields of study have made their presence felt. Experts in systems thinking and organizational learning, structure of intuition in decision making, and coaching (to name a few) whose perspective is not steeped in just the behavioral sciences, but a much more multi-disciplinary and inter-disciplinary approach, have emerged as OD catalysts or tools.
Organization development is a growing field that is responsive to many new approaches.
Kurt Lewin (1898–1947) is widely recognized as the founding father of OD, although he died before the concept became current in the mid-1950s. From Lewin came the ideas of group dynamics and action research which underpin the basic OD process as well as providing its collaborative consultant/client ethos. Institutionally, Lewin founded the "Research Center for Group Dynamics" (RCGD) at MIT, which moved to Michigan after his death. RCGD colleagues were among those who founded the National Training Laboratories (NTL), from which the T-groups and group-based OD emerged.
