Issue-based requirements elicitation and description

An Issue-based framework is outlined for: organising the products and process of requirements elicitation; conceptual prototyping to support validation and further elicitation; and re-using and re-applying past elicitation strategies to the current problem under investigation. The framework centres around the notion of Issues which may be loosely defined as some area of a problem which needs further investigation (W. Lam, 1992). The author uses the term problem to mean any system which is under investigation to highlight the fact that requirement analysis is a problem solving process. He considers the scenario of a software development project to develop a library system
