This document discusses organizational development (OD). It defines OD as a planned, systematic process aimed at improving an organization's effectiveness by implementing interventions at the individual, group, and structural levels. The key goals of OD are to align organizational elements with strategy, maintain organizational health, and improve capability. OD requires the involvement of all organizational levels and is led by an OD practitioner. The roles of an OD practitioner include diagnosing issues, facilitating change interventions, and evaluating impact. The document also explores the relationship between OD and human resource development (HRD), noting they work together but have distinct roles in driving organizational change.
