Applying Double Process Models for Verification in CMMI

During the CMMI perform, quality assurance is realized by two aspects: monitor, control and review the development process of a product, and test product requirements. In order to insure the correctness and validity of the product quality assurance, this paper presents a product verification method which needs to build two process models: product development process model and product requirement process model by advanced modeling technology with visualization and simulation; standardize the description of the two processes by integrality check; validate and optimize them by simulation; and then acquire the review contents for each develop phase and system test use case by process slice technique.
