Organization development is a planned, organization-wide effort led by top management to increase effectiveness and health through interventions. It responds to change by altering beliefs, attitudes, values, and structure using education strategies. The goal is to help organizations adapt to new technologies, markets, and challenges through changes to culture. Organization development uses action research methods like collecting data on problems and taking action based on analysis. It must address actual needs for change identified by the organization and involve them in planning and implementing changes.
