Realizing Quality Attributes of Service-based Business Processes: A Model-driven Approach

The agnostic, integrated and automated treatment of non-functional (quality) attributes into a business process realization is still a challenge. While functional attributes are already addressed by existing approaches, non-functional ones are commonly neglected. A systematic way of dealing with such attributes from the most abstract business level to their technical realization through service compositions is a complex task. In this context, this paper presents a model-driven approach, in which quality attributes are transformed until their technical enforcement at execution level. Additionally, two key characteristics of our approach are the agnostic treatment of the quality attribute being considered and its projection on standards such as URN (User Requirement Notation), UML for QoS and WS-Policy. To illustrate the proposed approach, an illustrative scenario of Supply Chain Management (SCM) is used.
