organizational development is a comprehensive and multi-dimensional concept, therefore it does not have a single, exact definition.
Instead, researchers focus on different points of OD definitions, according to their own field of interest. Some
OD definitions are submitted below in order to give an idea about that broad range. OD is mainly ensuring the
organization reach its goals by improving the individual and group performance (Burke et al., 2004). OD
activities are planned change efforts. OD is a concious and planned act of change jointly performed by managers,
change experts and employees to solve a problem. In the heart of this change act, achieving organizational
efficiency with humanitarian and democratic emphasis exists (Maes et al., 2011).
