Depending on the relevance of these results to the requirements of the specification, process re-engineering and testing may have a few cycles. The purpose of these cycles, a gradual decrease in the number of errors made in the design and pace of reducing the number of errors is an important indicator of the quality of the design process. But it must be taken into account that this process can be both convergent and divergent. The failure of the entire project, or part of it - this is a typical divergent iterative process of design and verification.<br />From a quantitative point of view design and verification process can be represented as a kind of predator - prey oscillation, where the means of verification eat the population of errors. That is, under this approach verification methodologies and tools are the predators, and the preys are the errors of the project.<br />We should also note that cyclic processes are crucial for the stability analysis of the design teams. From this perspective, the operation of any human group is a set of nonlinear cyclical processes. An example of such an analysis can be found here:<br />http://www.pmforum.org/library/papers/2010/PDFs/Pavel Barseghyanjan/FP-Barseghyan-DynamicsofHumanSocialBehavior.pdfJohn Goodpasture, PMPhttp://www.blogger.com/profile/04852874885562983654noreply@blogger.com
