A new critical chain project management based on social network and software maturity model

Abstract

With the rise of the Internet and the booming development of information technology, more and more IT projects have been launched on the information infrastructure. However, due to the large uncertainty and specificity of IT projects, the project delays are very serious. Both the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) can no longer meet the management requirements. This paper has improved the Critical Chain Project Management (CCPM) to strengthen the progress and quality management of IT projects. According to the characteristics of IT projects, an improved Critical Chain Project Management (NS-CCPM) had been proposed, and which was based on social network and software maturity models. Then the application of NS-CCPM has been specifically elaborated in three aspects: critical chain identification, buffer design, and buffer dynamic management. Finally, a case was shown, which used the Monte Carlo simulation method to verify the availability of NS-CCPM.
