Guidance plays a crucial role in requirements engineering (RE) as this task is both ill defined and highly intellectual. The guidance approach presented in this paper consists of supporting requirements engineers by a collection of enactable guidelines embodied in a computer environment. The key characteristics of the approach is its intention orientation. Guidance can be provided once the intention to be achieved has been elicited. Two kinds of guidance are proposed, step and flow guidance. The former supports the fulfilment of intentions whereas the latter helps in intention elicitation. The paper presents the two types of guidance, the corresponding guidelines and the Computer Aided Requirements Engineering (CARE) environment which supports their enactment. The approach is illustrated with the CREWS requirements engineering approach which elicits requirements through interleaved goal modelling and scenario authoring.
