Requirements Engineering

Book excerpt: This book presents a disciplined approach to the engineering of high-quality requirements. The approach covers the entire requirements lifecycle and integrates state-of-the-art techniques for requirements elicitation, evaluation, specification, analysis, and evolution. Modeling plays a central role in this approach. Rich, requirements-specific models provide a common interface to the various RE activities. Such models capture the multiple facets of the system-as-is and the system-to-be, comprising both software and environment components. The book puts a strong emphasis on systematic, replicable techniques for requirements engineering.
