Compared to structure or technology, people require the most skills and knowledge from managers to support them through the change process. Managers must prepare employees to be ready and willing to change. Managers must know how to lead and control effectively to obtain the most value for the organization.

It illustrates two views of the change process and how they affect the organization. Employee resistance, associated stress, and recommendations for managers to help employees overcome these challenges are discussed.
