Abstract
Since the problematic projects that cannot achieve the objectives on quality, cost or delivery time (QCD) have a risk to affect our customers' businesses as well as ours, it is important to prevent such projects. We have confirmed that the occurrence of such projects is caused largely by the insufficient design quality in the upper streams of developments, especially the fact that projects move to succeeding phases without completely find out issues on design. To improve this situation, we have adopted the statistical and quantitative management of the basic-design process using a reliability growth curve on the number of design issues found. With the implementation of this improved process, we have not missed any design issues at the basic-design phase, and successfully achieved the planned QCD of projects. In this paper, we will present the approach and the results of this improvement.
