The goal of QoSA is to addressaspects of softwarearchitecturefocusing broadly on quality characteristics and how these relate to the design of software arc- tectures. Speci?c issues of interest are de?ning quality measures, evaluating and managing architecture quality, linking architecture to requirements and imp- mentation, and preserving architecture quality throughout the lifetime of the system. Past themes for QoSA include Architectures for Adaptive Software S- tems (2009), Models and Architecture (2008), and Software Architecture, C- ponents, and Applications (2007). In this, the sixth incarnation of QoSA, researchers and practitioners dem- strated how speci?c sub-elements within an architecture lead to measurable quality in the implemented system. While clear challenges remain, the theme for QoSA 2010 was Research into Practice - Reality and Gaps.
