Employees also need time to adapt. Therefore, change activities should start from the assessment phase of the BPR and go through to implementation. Change management cannot be just an afterthought. The change hierarchy of needs All changes are not the same. Nor are the consequences perceived in the same manner by all participants in the change process.
People often use a progression of evaluations - questions that they ask to assess change.
This series of questions is somewhat analogous to Maslow's Needs Hierarchy, but adapted for process reengineering change. Maslow states that if a more basic level is not satisfied, a higher level will not be of importance to the organizational personnel. Management programs that ignore this theoretical construct usually fail. One of the reasons why change is so difficult is because managers bring their old perceptions with them. Managers frequently believe that a reengineering project will be exactly like previous efforts to reorganize to increase efficiency.
