Abstract

Software quality processes can be assessed with the Orthogonal Defect Classification COnstructive QUALity MOdel (ODC COQUALMO) that predicts defects introduced and removed, classified by ODC types. Using parametric cost and defect removal inputs, static and dynamic versions of the model help one determine the impacts of quality strategies on defect profiles, cost and risk. The dynamic version provides insight into time trends and is suitable for continuous usage on a project. The models are calibrated with empirical data on defect distributions, introduction and removal rates; and supplemented with Delphi results for detailed ODC defect detection efficiencies. This work has supported the development of software risk advisory tools for NASA flight projects. We have demonstrated the integration of ODC COQUALMO with automated risk minimization methods to design higher value quality processes, in shorter time and with fewer resources, to meet stringent quality goals on projects.
