As software ages, its quality degrades, leading to pathologies such as architectural decay. Architectural decay is hard to fight against. First, it is a slow drifting process that results from the natural evolution of software as new features pull the system in new directions. It is not something that one can fight against on a day to day basis. Second, restructuring a legacy system is a costly...

Many software architecture evaluation methods, proposed by the research community, have a common problem of engaging the same architects to perform architecture design and evaluation. This violates the independence of quality assurance and hence may lead to biased evaluation, thereby resulting in inferior architectural design. In this paper, we analyze current approaches and issues to software ...

An important part of hospital information systems (HIS) evaluation is the quality assessment of its architecture, i.e. the structure of its IT infrastructure. Therefore, quantitative architectural quality criteria are needed. On the basis of relevant architectural components of a HIS defined by 3LGM2, the following quality criteria were defined: functional redundancy, functional under-saturatio...

This paper proposes an empirical approach to the visualization phase of architectural images, employing established concepts, methodologies, and measurement techniques found in media psychology and user-centered studies. The paper proposes a human-centered approach for conceptualizing visualization technologies and evaluating the quality concept of images to simulate a satisfactory architectura...

Challenges in designing effective groupware include technical issues associated with concurrent and distributed work and social issues associated with supporting group activities. To address some of these problems, we have developed a quality-centered architectural design framework that links requirements analysis to architectural design decisions for groupware systems. The framework supports r...

In this paper, we first identify key architectural properties related to quality aspect of web services architecture. Current web services architectural styles are then summarized. Finally, we give the evaluation analysis with evaluation analysis for web services architect.
