QoS in CBSE 2003 - Proceedings of the 1st International Workshop on Quality of Service in Component-Based Software Engineering, Workshop at Ada-Europe 2003, Toulouse, France, June 2003

In the overall topic of reliable software, we were specifically interested in improving the way software developers con manage the complexity of developing software which is most of the time distributed, based on existing reused pieces, and with stronger and stronger timing constraints. The goal of this workshop was to look at issues related to the integration of non-functional properties expression, evaluation, and prediction in the context of component-based software engineering development. It is now widely recognized that what makes Component-Based Software Engineering (CBSE) hard to efficiently use is the fact that components are easy to produce but not easy to compose. This scope is addressed by a number of ongoing researches. In the context of this particular workshop we have focused on the difficulty of predicting the overall behavior and offered quality of service (in a broad sense, e.g. performance, dependability) of a composite out of its "internal" components. This implies that a software builder should have the behavior and the quality of service offered and required of each components expressed in some way, as well as some support tool or underlying framework supporting the composition of these added-value features. The aim of this workshop was to bring together practitioners and academics that are currently working around these topics to highlight the ongoing solutions and the problems encountered. This workshop, has been held in conjunction with the 8th Reliable Software Technologies international conference (Ada-Europe 2003), in Toulouse, France, on June 20th 2003.
