In the IT project development process, project change is inevitable throughout the entire life cycle. Change in the project has become the most prominent source of risk in the development of the project: a direct impact on the time, cost and quality of the software developing project. Project change is one of the most important causes of the failure of many projects. This paper analyses the reasons why the project changes, the impact of project change and the scope of the personnel involved, proposes a change management solution, and gives an implementation procedure of change management. The solution will enable project changes to be managed in an orderly and effective manner, and consequently ensure the projects a successful completion and a higher quality.
