Free registration required

Executive Summary

This paper describes a method for systematically analyzing requirements of an IT system so one can create a component model that addresses the requirements in a holistic way. Explore sample requirements with uses cases and "Stress cases" to identify potential conflicts between functional and non-functional requirements. Stress cases must be addressed by defining an optimum solution that resolves the conflict. Learn how functional and non-functional requirements are opposing forces that are handled similarly to forces in civil engineering structures.
