A conceptual framework for requirements engineering

A framework for assessing research and practice in requirements engineering is proposed. The framework is used to survey state of the art research contributions and practice. The framework considers a task activity view of requirements, and elaborates different views of requirements engineering (RE) depending on the starting point of a system development. Another perspective is to analyse RE from different conceptions of products and their properties. RE research is examined within this framework and then placed in the context of how it extends current system development methods and systems analysis techniques.
