Organizational development (OD) aims to improve organizational effectiveness by implementing planned changes. It addresses issues like changing workforce needs and technology. The OD process involves needs identification, diagnosis, design, implementation, and evaluation. Common OD techniques include sensitivity training, team building, intergroup development, process consultation, and survey feedback. These techniques help build more effective interpersonal relationships and communication within organizations. Planned change follows steps like recognition of the need for change, developing solutions, implementing actions, and stabilizing and evaluating changes made. Readiness for change, quality solutions, and managing resistance are key factors for successful organizational development.
