5. A GENERAL CHANGE PROCESS MODEL
Change management seeks to forecast possible changes; identify changes that have already occurred; plan
preventive measures; and coordinate changes across the entire project [8]. Small reworks with minor impacts
do not need to go through a formal change process. However, changes with noticeable impacts, either reworks
or change orders, all require following a formal process in change management.
A generic change process model is considered to have five stages in a sequence: identify, evaluate & propose,
approve, implement and review (Figure 2). The process model is conceptualized based on a synthesis of the
change process models reviewed in the literature and the characteristics of computational environments.
