On the expressiveness of business process modeling notations for software requirements elicitation

Abstract

Business process models have proved to be useful for requirements elicitation. Since software development depends on the quality of the requirements specifications, generating high-quality business process models is therefore critical. A key factor for achieving this is the expressiveness in terms of completeness and clarity of the modeling notation for the domain being modeled. The Bunge-Wand-Weber (BWW) representation model is frequently used for assessing the expressiveness of business process modeling notations. This article presents some propositions to adapt the BWW representation model to allow its application to the software requirements elicitation domain. These propositions are based on the analysis of the Guide to the Software Engineering Body of Knowledge (SWEBOK) and the Guide to the Business Analysis Body of Knowledge (BABOK). The propositions are validated next by experts in business process modeling and software requirements elicitation. The results show that the BWW representation model requires to be specialized by including concepts specific to software requirements elicitation.
