Abstract
We had worked on the existing machine upgrade project. In various severe restrictions conditions, without schedule being delayed, by smooth project progress, this project attained the improvement in a performance as we expected. In this paper, we report the success factor that is considered both in terms of "the extract from the project management WBS" and "the particular subject and measure on this project." In terms of "the project management WBS", we selected and considered four activities, "scope management", "risk management", "time management" and "communication management". Respectively, an investigating of a main work item and clarification of a role assignment, the plan for risk quantification, master schedule crafting with high accuracy in the planning stage and clarification of a solution person in charge and a term were important factors. In terms of the particular subject and measure on this project, there were three success factors, conversion tool for "doing application repair work correctly", the planned change rehearsal for "shortening the business suspension time during a change" and planned data arrangement towards the next machine upgrade for leaving a reusable working artifacts. Seven points are the success factors of this project, and it turns out that it was altogether concerned with the planning stage. Therefore, for a success of a project, this report concludes that thorough investigation of issues which foresees all processes and the work definition for dealing with the issues are important at a project planning stage.
