The notion of an "Information SuperHighway" has attracted considerable attention. It offers the possibility to access information from around the world in support of many important applications in areas such as finance, manufacturing, and transportation (e.g., global risk management, integrated supply chain management, global in-transit visibility.) Unfortunately, there are significant challeng...

Over the years, research on software architecture has identified architectural styles. In this paper we consider five of such styles, and analyze whether these styles can also be found in business value models for networked enterprises. To this end, we analyze 17 evalue models, as discussed in 29 academic papers or book chapters. We also consider whether the quality attributes related to the so...

Restructuring is an important activity to improve software internal structure. Even though there are many restructuring approaches, very few consider the refactoring impact on the software quality. In this paper, we propose an semiautomatic software restructuring approach based on quality attributes. We rely on the measurements of the Quality Model for Object Oriented Design (QMOOD) to recommen...

Business to consumer m-commerce services are here to stay. Their specifics, as software artifacts, indicate that they are primarily and most importantly user-driven; as such user perceived quality assessment should be an integral part of their design process. Mobile design processes still lack a formal and systematic quality control method. This paper explores m-commerce quality attributes usin...

The problem of composing services to deliver integrated business solutions has been widely studied in the last years. Besides addressing functional requirements, services compositions should also provide agreed service levels. Our goal is to support model-based analysis of service compositions, with a focus on the assessment of non-functional quality attributes, namely performance and reliabili...

A semantic quality attribute of a modelling language is a desired semantic characteristic that is common to all models specified in that language. A modeller can enjoy the luxury of not having to model the invariants of the behaviour that are implicitly enforced by the semantic quality attributes. In this paper, we introduce three semantic quality attributes for the family of big-step modelling...

Spatial sound reproduction gives rise to new challenges for those trying to evaluate sensory features contributing to perceived quality. Recent technical developments have enabled the delivery of sophisticated multichannel audio signals to consumers, over links that range very widely in quality, requiring decisions to be made about the tradeoffs between different aspects of audio quality. Spati...

Recent surveys on e-commerce sites confirm the increased use of the Web for shopping. The reasons of these trends have been attributed to different factors such as convenience, saving time, absence of sales pressure, among others. However, an essential site characteristic that should also be taken into account is the quality in use. In this paper, we present a case study on five ebookstores in ...

Design and development of software is difficult task due to the changing requirements of usres. To develop good quality software, our main focus is on analysis of quality attributes according to the users’ requirement, but it increases the complexity. So it’s a complex task to establish a relationship between users’ requirements and quality attributes due to the frequent change in requirements....
