With the proliferation of Web services and their wide adoption as a novel technology for business-to-business interactions on the Web, Quality of Web Services (QoWS) management has witnessed considerable interest in recent years. Most of the existing works regarding this issue do not provide support for the overall QoWS management operations and are very often limited to a subset of these operations. Some of these works propose QoWS solutions for only basic web services while others propose solutions for composite web services. In this chapter, we propose to extend the Service Oriented Architecture (SOA) with a framework for QoWS management in which services may be basic or composite Web services. The framework uses a layered approach to provide support for the most common QoWS management operations, which include QoWS specification, QoWS verification, QoWS negotiation, and QoWS monitoring. These operations are supported at both the design and the development phases of Web services.
