摘要：In the paper Output driven Information systems (IS) requirements specification method (ODRES) is overviewed emphasizing the problems of recording certain requirements. It is suggested that the method can be extended with business rules recording capabilities. Business rules-based requirements specification method is used to extend ODRES by incorporating method’s rules submodel into an ODRES metamodel in order to support non-structural business rules as additional knowledge about static and dynamic aspects of IS. Presented extension of ODRES concerns only the specification of dynamic aspects of IS. BRS RuleSpeak, which is the basis for a suggested rules submodel, is also overviewed in the paper and the benefits of the extension are outlined.
