RISE 2006 constituted an international forum for researchers and practitioners interestedintheadvancementandrapidapplicationofnovel,integrated,orpr- ticalsoftwareengineeringapproaches,beingpartofamethodologicalframework, that apply to the development of either new or evolving applications and s- tems. It provided a good opportunity to present and discuss the latest research results and ideas in the rapid and e?ective integration of software engineering techniques. The ERCIM (European Research Consortium for Informatics and Mathematics) RISE working group selected application areas such as the Web, mobility, high availability, and embedded and user-interface software in speci?c industry sectors comprising ?nance, telecommunications, transportation (avi- ics, automotive) and eGovernment. The research issues covered stemmed from the following software engineering domains: – software and system architectures – software reuse – software testing – software model checking – model driven design and testing techniques – model transformation – requirements engineering – lightweight or practice-oriented formal methods – software processes and software metrics – automated software engineering – software patterns – design by contract – defensive programming – software entropy and software re-factoring – extreme programming – agile software development – programming languages – software dependability and trustworthiness All papers submitted to this workshop were reviewed by at least two m- bers of the International Program Committee. Acceptance was based primarily on originality and contribution. We have selected, for these proceedings, 10 - pers amongst 30 submitted and an invited paper. The organization of such a workshop requires a lot ofwork.
