Quality Misuse

There are several methods for the derivation and analysis of detailed non-functional requirements. They often are designed for a special application, like misuse cases for top-down derivation of requirements detailing the quality attribute “security”, or ATAM for evaluating given architectural alternatives. In this work, we apply misuse cases to any other quality attribute (e.g. usability, efficiency) to develop a misuse-based method for deriving detailed nonfunctional and functional requirements. Doing so, we find that generalizations must be made to the definitions of the misuse case concepts, and new concepts must be included. With this paper, we want to stimulate a discussion about the general usefulness of our approach and definitions.
