On detecting and handling inconsistencies in integrating software architecture design and performance evaluation

We consider the problem of detecting and handling inconsistencies in software development processes using a graph based approach. It seems to be a natural way to express the various options and possibilities in attacking the problem. We apply the techniques developed in the area of software architecture design which uses in a structured way performance models in order to produce a design which incorporates also nonfunctional requirements in terms of quantitative performance.
