Organizational development is best defined as
Organization development (OD) is a deliberately planned, organization-wide effort to increase an organization's effectiveness and/or efficiency, and/or to enable the organization to achieve its strategic goals.OD theorists and practitioners define OD in various ways. The basic building blocks of an organization are groups (teams). 2  Therefore, the basic units of change are groups, not individuals. 3  An always relevant change goal is the reduction of inappropriate competition between parts of the organization and the development of a more collaborative condition.
