Engineers have little time for requirements elicitation and their validation, because they still have to make a great effort to write down concrete use cases. Although concrete use cases are important for deriving test cases, it is possible to free engineers from the routine work of defining similar use cases repeatedly and at the same time keeping consistency in requirements elicitation. We propose one solution concerning these difficulties. The requirements description metamodel called RD-metamodel integrates the activity graph metamodel and use case metamodel. It supplies a mechanism of use case writing with multiple perspectives: resource-reference, resource-structure, activity-sequence, process, and the actor's perspective.
