4 Preface Much of a software architect s life is spent designing software systems to meet a set of quality requirements. General software quality attributes include scalability, security, performance or reliability. Quality attribute requirements are part of an application s non-functional requirements, which capture the many facets of how the functional requirements of an application are achieved. Understanding, modeling and continually evaluating quality attributes throughout a project lifecycle are all complex engineering tasks which continue to challenge the software engineering scientific community. While we search for improved approaches, methods, formalisms and tools that are usable in practice and can scale to large systems, the complexity of the applications that the software industry is challenged to build is ever increasing. Thus, as a research community, there is little opportunity for us to rest on our laurels, as our innovations that address new aspects of system complexity must be deployed and validated. To this end the 5th International Conference on the Quality of Software Architectures (QoSA) 2009 focused on architectures for adaptive software systems. Modern software systems must often reconfigure their structure and behavior to respond to continuous changes in requirements and in their execution environment. In these settings, quality models are helpful at an architectural level to guide systematic model-driven software development strategies by evaluating the impact of competing architectural choices. At run time, quality models can play an important role in enabling calibration and validation of a system model to accurately reflect the properties of the executing system. This leads to the idea that architectural models should continue to exist at run time to facilitate the necessary dynamic changes that can support self-adaptation of the implemented system. In so doing, the conference continued QoSA s tradition of using software architectures to develop and evolve high-quality software systems. In line with a broad interest, QoSA 2009 received 33 submissions. From these submissions, 13 were accepted as long papers after a careful peer-review process followed by an online Program Committee discussion. This resulted in an acceptance rate of 39%. The selected technical papers are published in this volume. For the third time, QoSA 2009 was held as part of the conference series Federated Events on Component- Based Software Engineering and Software Architecture (COMPARCH). The federated events were QoSA 2009, the 12th International Symposium on Component-Based Software Engineering (CBSE 2009). Together with COMPARCH s Industrial Experience Report Track and the co-located Workshop on Component-Oriented Programming (WCOP 2009), COMPARCH provided a broad spectrum of events related to components and architectures. By integrating QoSA s and CBSE s technical programs in COMPARCH 2009, both conferences elaborated their successfull collaboration thus demonstrating the close relationship between software architectures and their constituting software components. Among the many people who contributed to the success of QoSA 2008, we would like to thank the members of the Program Committees for their valuable work during
