This paper outlines the functionality of an expert system currently under development. The ‘Requirements Assistant for Telecommunications Services‘ (RATS) is designed to actively assist the development of new telecommunications services. It helps during the early parts of the development life cycle, during requirements capture and analysis, leading to formal specifications of the service at different stages of refinement. Facilities for requirements traceability, rationale and documentation as well as impact analysis of requirements change are provided. The tool contains comprehensive knowledge bases with the main characteristics of the telecommunications domain and the development process of telecommunications services, which enable the tool to actively guide the software developer. Assistance is provided for three dimensions of the development process of functional requirements — refinement, formality and completeness. The output of the RATS tool enables a smooth transition to the ITU-recommended Specification and Description Language (SDL), which allows automated analysis of static and dynamic properties as well as code generation.
