QUALITY OF SOFTWARE ARCHITECTURES AND SOFTWARE ...

The goal of software engineering is to achieve high-quality software in a cost-effective 
timely  and reproducible manner. Advances in technology offer reductions in cost and schedule 
but their effect on software quality often remains unknown. The International Conferenceon the
Quality of Software Architectures(QoSA 2005)focusedon software architectures and their relation
to software quality  while the International Workshop on Software Quality (SOQUA 2005) mainly
focused on quality assurance and more precisely on software testing. These events complement
each other in their view on software quality. One of the main motivations for explicitly
modelling software architectures is to enable reasoning on software quality. From a software
engineering perspective  a so- ware architecture not only depicts the coarse-grained structure
of a program  but also includes additional information such as the program's dynamics (i. e.  
the ?ows of c- trol through the system) and the mapping of its components and connections to e-
cution environments (such as hardware processors  virtual machines  network conn- tions  and
the like). In this area  QoSA 2005is concernedwith researchand experiences that investigate the
in?uence a speci?c software architecturehas on software quality - pects. Additionally the
developmentof methodsto evaluate software architectureswith respect to these quality attributes
is considered to be an important topic. The quality - tributes of interest include external
properties  such as reliability and ef?ciency  as well as internal properties  such as
maintainability.
