Modeling Business Strategy in E-Business Systems Requirements Engineering

This paper proposes a conceptual modeling approach for requirements engineering for e-business systems that enables alignment of systems requirements with business strategy. Jackson problem diagrams and goal modeling are employed to capture business strategy. As a means of linking abstract, high-level business requirements to low-level system requirements, we leverage the paradigm of projection in both problem diagrams and goal models in parallel. We use Jackson context diagrams to describe the business model domain context. Goal modeling is used to both represent requirements and describe the objectives of business strategy. The feasibility of the approach is demonstrated by its application to a case study from the literature.
