Change management is a systematic approach to dealing with change from both an organizational and individual perspective. It involves adapting to change, controlling change, and effecting change. Change management is defined as transitioning individuals, teams, and organizations to a desired future state. It is the process of managing the people side of change to achieve business outcomes. Reasons for change management include dealing with crises, coping with globalization, improving performance gaps, improving organizational culture, introducing new technologies, identifying opportunities, and reacting to internal and external pressures. Key aspects of successful change management include having a compelling need for change, a clear vision, senior management commitment, effective communication, preparation for the unexpected, and celebrating small wins.
