Organization development is the systematic application of behavioral science knowledge at various levels within an organization to create planned change, according to Newstrom & Davis. It relies on systems orientation, understanding causality, and assumptions about organizations. The benefits of organization development include increased motivation, productivity, quality of work, and job satisfaction, as well as improved teamwork, conflict resolution, commitment to objectives, and willingness to change. Potential limitations are the major time and expense required, delayed payoffs, possible failure or harms, and difficulties with evaluation and cultural compatibility.
