Abstract
In Hitachi Software company-wide process improvement movements are being conducted. One of the major improvement activities is "process QA" in which a third party (Quality department) audits the process adherence against project plan or project defined processes. In this paper effect of process QA on management support is analyzed by estimating the efforts and costs that would be lost, if there were no process QA activities. As a result, it is shown that process QA has an effect to prevent risks from becoming actual problems. The ROI of this effect is estimated to be a high value of 6.3-9.8.
