Abstract
In this paper, we report on the integration of informal, semiformal and formal requirements specification techniques. We present a framework for requirements specification called TRADE, within which several well-known semiformal specification techniques are placed. TRADE is based on an analysis of structured and object-oriented requirements specification methods. In this paper, we combine TRADE with the logic-based specification language Albert II and show that this leads to a coherent formal and semiformal requirements specification. We illustrate our approach with examples taken from a large distributed telecommunication application case study performed in the context of the Esprit project 2RARE.KeywordsOperating EnvironmentRequirement EngineerVideo ServerSoftware RequirementSubject DomainThese keywords were added by machine and not by the authors.
