For the success and adoption of web services it is essential that not only functional concerns (FC) are addressed but also non-functional concerns (NFC) such as security, reliable messaging, performance, and availability. The support for non-functional concerns encompasses two aspects: the specification and the enforcement and we focus thereby on two views: the black box view (only the interface) and the gray box view (the internal process of a composite service). In this paper we identify the most important requirements for the specification and enforcement of NFCs whilst taking the two different views into account. Furthermore, we present a thorough analysis of the state-of-the-art works based on those requirements and identify areas where future work has to be conducted to fulfill all identified requirements.
