Abstract
In order to execute the final target of software quality steadily, it is very effective to predict the achievement level of the target quality from project performance and to take measure as early as possible. By forecasting and evaluating the achievement of the final quality target, we can improve the running project process continuously and prevent reworking. As the result, we can enhance the achievement accuracy of planned cost and delivery date. In addition, our organization gets mature as the organization that can complete the project as planned and achieve our business goal. In this paper, we describe the establishment of the process performance model, which can forecast the achievement of the final quality from project start by using project performance data, and our efforts.
