Towards a quality model for choreography

Quality attributes of software products like maintainability and reliability have been widely studied in the Software Engineering literature. Their understanding has proven instrumental for developing best practices and tooling support that ultimately result in higher-quality software. In this paper we investigate external quality attributes (i.e. aspects of quality visible to the end user) of service choreographies. Service choreographies are service compositions that specify completely distributed, message-based interactions among services. Our work is a first step towards the definition of a quality model for service choreographies.
