RESEARCH ON CRITICAL CHAIN MANAGEMENT AND RISK MANAGEMENT IN PROJECT IMPLEMENTATION MANAGEMENT

According to Standish Group's research, more than 30% of IT projects are unfinished, and about 73% are delayed or exceeded the budget in those completed projects. On average, the cost is 189% of the original planned and the length of completion cycle is 222% of the planned length. This indicates that there are shortcomings in the traditional project management mode. However, critical chain theory provides some improvement method. This paper focuses on the application of critical chain theory to enhance the ability to completing projects on schedule and effectively reduce cost.
