KAOS-β: A goal-oriented process model for EIS

There is increasing demand for approaches to develop more effective enterprise information systems (EIS). A possible solution is to focus on eliciting and elaborating goals prior to capturing EIS requirements. Focusing on EIS goals could help the developer team and other stakeholders (particularly decision makers) achieve a shared and structured understanding of the goals of the EIS and the overall enterprise. We present an investigation of the use of the KAOS approach to goal modelling in the domain of EIS. As a result, we propose a tailoring of KAOS for this domain; the tailoring has been developed through empirical studies. Our tailoring, called KAOS-β, is described, and an empirical evaluation is presented, investigating its applicability for defining and structuring the goals of groups of EIS.
