Abstract
To meet the deadline of large SI project there are many difficulties. 83% of typical SI projects missed its deadline, and 18% of them were called off. So far a standard process such as PMBOK has been systematized and the knowledge system of project management has been established. However, none could shorten the project period. CCPM (Critical Chain Project Management) is an approach applied to a large SI project, and the schedule which was set with the conventional period estimation method (four and a half months) was shortened by 28% (to three months). A "buffer" is provided at the phase-end and the entire project progress can be understood its consumption, not the progress of each task. At the planning phase, a work network considering resource restriction is created by eliminating multitasking and controlling number of tasks not over than 300. At the action phase, aggressive remaining day of each work from workers is brought out and buffer consumption is decided depending on the priority. Moreover, the daily meeting is held depending on the project organizational hierarchy to solve the issues rapidly. In this paper, it is proved that applying CCPM is effective to the SI project
