The document summarizes a presentation about using quality models in requirements engineering for software systems. It discusses different approaches to assessing software quality, including quality models. It then examines specific quality models like ISO/IEC 9126-1 and how they can be used in requirements elicitation, evaluation of products, definition of requirements patterns, and other stages of requirements engineering. The presentation also outlines current research by the GESSI group related to quality models and requirements engineering.
