Which term refers to someone who is responsible for changing existing behavior patterns?

The term that refers to someone who is responsible for changing existing behavior patterns is "change agent." A change agent plays a crucial role in initiating and managing change within organizations or systems. They can help identify the need for change, create a vision for what the change should look like, and facilitate the process by encouraging others to adopt new behaviors or practices.

Change agents often work closely with individuals and groups to understand their resistance to change and to develop strategies that support a smoother transition. Their role is essential in fostering an environment where change is not only accepted but embraced, leading to improved outcomes and enhanced performance.

The other roles mentioned, such as policymakers, team leaders, and conflict mediators, focus on different aspects of organizational dynamics. Policymakers primarily deal with the establishment of guidelines or rules that govern behavior, team leaders facilitate group activities towards achieving specific goals but may not focus specifically on changing behavior, and conflict mediators work on resolving disputes rather than initiating change processes. Therefore, a change agent is distinctly characterized by their responsibility in transforming behavioral patterns.
