Change is an inevitable aspect of life and can cause stress. Change is expected, respected, and sometimes needed in organizations. Leaders must determine effective strategies for managing change, implementing change, monitoring change and stress. Each organization has a unique way of responding to internal and external pressures for change. Leaders are responsible for identifying these pressures and responding to them with appropriate measures. Most change is a result of the identification of a problem. Identifying the problem is the first step, but evaluating the need for change is an important step in determining a path to implementation. Successful leaders are not bound to any one change strategy, but choose whichever strategy best fits the situation.
