General software quality attributes include scalability, security, performance or reliability.

To this end the 5th InternationalConferenceon the Quality of SoftwareArchitec- tures (QoSA) 2009 focused on architectures for adaptive software systems.

This resulted in an acceptance rate of 39%. The selected technical papers are published in this volume.

The feder- atedeventswereQoSA2009,the12thInternationalSymposiumonComponent-Based SoftwareEngineering(CBSE 2009).Togetherwith COMPARCH’s IndustrialExperi- enceReportTrackandtheco-locatedWorkshoponComponent-OrientedProgramming (WCOP 2009), COMPARCH provided a broad spectrum of events related to com- ponents and architectures. By integrating QoSA’s and CBSE’s technical programs in COMPARCH 2009, both conferences elaborated their successfull collaboration thus demonstratingthecloserelationshipbetweensoftwarearchitecturesandtheirconstitut- ingsoftwarecomponents.

One approach that has been recognized to facilitate the development of complex systems is proposed by the component-basedparadigm [2], which promotesbuilding an application by assembling software components. Componentassemblies are spec- ified at design-time but many component-basedplatforms offer also the capability of modifyingassembliesatruntime,makingtheseplatformsinterestingcandidatestorun adaptiveapplications.Itisthusnotsurprisingthatsomecomponent-basedapproaches have proposed extensions to supportthe developmentof autonomic systems [3,4].
