Description

We focus on personnel distribution, and modeling structural equation model. The proposed model is fitted well to the real project data. And the prediction accuracies of development Elapsed Time improve about twice in terms of the determination coefficients. Further the complex causal structure among the Effort, Elapsed Time, Defect Density (After that we abbreviate it to QCD) is so effectively quantified and visualized by using the path diagram. Summarizing results of the proposed modeling that necessary inputs to the project and can be estimated accurately and that impacts of delays on several requirement definitions into the planned project performances can be also clarified to lead the effective counter actions. In addition, I show that the estimated precision of the Elapsed Time and Defect Density is improved with few variables through these. It enables the setting of the standard value of QCD to raise estimated precision of QCD.
