Variations in Critical Success Factors Over the Stages in the Project Life Cycle
通过对408名项目经理或团队成员调查，发现项目关键成功因素在生命周期四个阶段中的重要性会显著变化，最终确定了八个关键因素。
Afield study was conducted to investigate changes in the importance of project critical success factors across four stages in the project life cycle. A total of 408 project managers or project team members cur-rently involved in a project responded to the questionnaire. Ridge regression analysis was performed on the initially derived ten critical success factors, reducing the final number of critical success factors to eight. A stepwise regression was then done on the critical success factors at each of the four stages in the project life cycle. Results indi-cated that the relative importance of several of the criticalfactors change significantly based on life cycle stages.
