Transformation approach from KAOS goal models to BPMN models using refinement patterns

It is important to make sure that software satisfies stakeholders' requirements. However, as software has been getting more large-scale and complicated in recent years, it has certainly become more difficult to satisfy requirements. Even if there are goal-oriented requirements analysis approaches as techniques to systematically satisfy stakeholders' requirements, it is still difficult to maintain consistency of goal models and other requirements artifacts. In this paper, we propose a transformation approach that transforms models of KAOS, a well-known goal modeling methodology, into preliminary BPMN models by using refinement pattern of KAOS in a systematic way. It can assure consistency between systematically defined user's requirements and their realization process.
