Change management is the process of transitioning an organization from its current state to a desired future state in a planned and managed manner. It involves developing a vision for change, strategies for implementing change, and addressing resistance. A change management strategy involves understanding the specifics of the change, identifying impacted groups, establishing a team structure and sponsor coalition, assessing risks and resistance, and developing special tactics. Key elements of a strategy include situational awareness, supporting structures, and strategy analysis.
