Towards a model-driven approach for treating quality attributes of service-based business processes

摘要

A systematic way for treating non-functional (quality) attributes into the business process management lifecycle is still a challenge. The agnostic, integrated and automated treatment of these attributes from the most abstract business level to their technical realisation at execution level is a complex task. In this context, this paper presents a model-driven approach centred on quality attributes of business processes. Additionally, two key characteristics of our approach are the agnostic treatment of the quality attribute being considered and its projection on standards such as user requirement notation (URN), UML for QoS and WS-Policy. To illustrate the proposed approach, a supply chain management use case is used. Finally, in order to evaluate the model-driven approach, an evaluation plan based on goal/question/metric (GQM) is defined, providing the rationale to define and to apply evaluation metrics of interest.
