Quantitative measurement of software reliability remains an elusive goal. Simultaneously, there is an ever increasing critical dependency on software-based systems in the human infrastructure. There is a great deal of research in addition to well-intentioned methods and practices focused on improving the reliability of software-based systems. To date, most of which still only yields qualitative...

This research addresses difficulties in measuring e-commerce success by implementing the DeLone and McLean (D&M) model of IS success (1992, 2003) in an e-commerce environment. This research considers the influence of quality on e-commerce success by measuring the information quality and system quality attributes of an e-commerce system and the intention to use, user satisfaction and intention t...

INCITS W1 is the U.S. representative of ISO/IEC JTC1/SC28, the standardization committee for office equipment. In September 2000, INCITS W1 was chartered to develop an appearance-based image quality standard. (2) The resulting W1.1 project is based on a proposal that perceived image quality could be described by a small set of broad-based attributes. There are currently five ad hoc W1.1 teams, ...

John Morley [email protected] A system designer faces several challenges when specifying security for distributed computing environments or migrating systems to a new execution platform. Business stakeholders impose constraints due to cost, timeto-market requirements, productivity impact, customer satisfaction concerns, and the like. And users exercise power at the desktop over computing reso...

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...
