Abstract
In the case of a community starting and carrying on, or any event periodically held, there might be a dedicated person who plays leading role to expend significant efforts such as planning a schedule, managing the cost, and guaranteeing deliverables on agreed upon date. However, these efforts are not complying with the PMBOK guide and the key person has been managing in his/her own fashion. Because there might be neither understanding importance of the management nor taking over the know-how which the project's members have acquired due to almost all members have tuned over. The ACM/ICPC is held by a university in Japan rotating every year. We entered the ACM/ICPC as the stuff. We propose the management methodology for the periodic event. The proposing methodology is based on the experiences as the stuff member of the ACM/ICPC project and observing the project in conformity with the PMBOK, And the causes of a range of problems of the management and actions to be performed are discussed.
