Abstract :
Proposes a pattern language for socio-technical system design to inform the validation of system requirements. The development of this language takes its inspiration from C. Alexander´s (1979) pattern language for building design in architecture. Our pattern language identifies different types of patterns which fulfil different roles in the requirements engineering process. This pattern-based validation approach has been operationalised in the CREWS-SAVRE (Specification And Validation of REquirements) software prototype, developed as part of the ESPRIT 21903 CREWS (Co-operative Requirements Engineering With Scenarios) project. CREWS-SAVRE applies patterns to both scenarios and requirements documents to detect missing and incorrect system requirements, as well as to recommend new requirements which can improve the design of the socio-technical system
