This document discusses organizational change and development. It begins by defining organizational change as a modification to an organization's structure, processes, or products that significantly impacts work and staff. Changes can include alterations to structure, operations, roles, or working conditions/environment. Forces driving change include both external factors like technology and internal factors like managerial changes. The document then examines the process of change management and types of changes. It also discusses sources of individual and organizational resistance to change and tactics for managing resistance like communication, participation, and negotiation. Finally, it provides an overview of organizational development as a planned educational strategy for change using sensitivity training and collaboration between internal/external change agents.
