Software quality assessment and improvement in service-oriented environments

点击翻译按钮获取中文摘要

The emergence of SOA (Service Oriented Architecture) as a general architectural pattern for modern software systems and the creation of a series of universal standards for web services delivery provides an excellent opportunity to explore how the quality of software can be used as a major factor in the selection of IS (Information System) services. These new SOA-based systems expose service capabilities and make more evident to users the importance of delivering quality systems and associated support services. My primary objective is to uncover methods (processes and tools) that measure and improve upon the quality of IS services delivered to users. Specific projects undertaken will be focused upon are i) defining a model for measuring and advertising service quality, ii) determining and assessing how this model can be incorporated as part of an extended registry capability for service-oriented applications and iii) exploring approaches for testing IS services to help ensure defined levels of service quality.
