Requirement Patterns

Many recent studies still show how a significant percentage of software projects are out of budget, suffer delays or simply have to be cancelled. One of the most recognized causes for this scenario is the failure in producing a good set of software requirements. Methods for improving the quality of software requirement specifications are therefore needed. Pattern-based requirements engineering is one of such methods. The definition and use of a software requirements pattern catalogue supports the elicitation, validation, documentation and management of requirements. By designing an appropriate catalogue, an IT organization will have a starting point for the requirements engineering activity reducing the associated costs and producing better requirements. This seminar will introduce the state of the art in requirement pattern research, will address practical issues on the design of a pattern-based approach to requirements engineering, and will present some real examples from ongoing projects.
