An approach to non-functional requirements analysis at software architecture level

With the growing complexity and size of software systems and applications, the evaluation of these systems in development process, especially in the first phases are very important. In this paper a framework consisting of three parts is introduced. With the help of the integration of the software architecture description and requirement evaluation this framework minimizes the gap between software engineers and non-functional requirement analysis. In this framework, a general structure based on XML is provided for Petri nets extensions in order to be suitable for all Petri net extensions. Also it was indicated how different analysis methodologies can be integrated in our framework.
