Software Quality Revisited, Ronan Fitzpatrick
Software Quality Revisited, Ronan Fitzpatrick
Conference papers
Definitions of software quality have focused on software product quality factors. Quality that focuses on product quality is referred to by Kaoru Ishikawa as a narrow view of quality and he suggests that a broader more embracing and inclusive view is really necessary. The requirements of successful E-Commerce Web sites demonstrate this view. While the site might be considered as the product, Web site producers, owners and visitors also have a “quality” requirement. This broader view gives rises to the need to research and understand quality-of-development, quality-of-ownership, quality-of-engagement as well as quality-of-product. From the quality-of-product perspective, while many of the …

Usability is a significant factor in the creation of quality software products which is an important focus of the software engineering syllabus. Usability is also a significant factor in the study of Human-Computer Interaction (HCI). Despite the connection, software quality and the rigours of the software engineering discipline are not used in the teaching of HCI and visa versa. Consequently, students undertaking software engineering courses are not fully exposed to usability issues and HCI students often miss out on the disciplines of software engineering. This paper presents a quality focused conceptual model - the Software Quality Star - which can …

A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix
Conference papers
Recent international quality standards and European Community legislation have identified new software quality factors. These new factors include suitability, installability and adaptability. Other quality factors need to be reviewed in the light of these developments. This has impacted on established commercial usability evaluation methods to the extent that it is appropriate to ask if these evaluation methods comply with the new standards and legislation. In order to answer this question the commercial evaluation methods need to be appraised (meta-evaluation) using a suitable method appraisal process. This paper describes such an appraisal process which specifically addresses the many considerations raised by …

Usable Software And It's Attributes: A Synthesis Of Software Quality: European Community Law And Human-Computer Interaction., Ronan Fitzpatrick, Catherine Higgins
Conference papers
Strategic managers and IS professionals who are responsible for specifying, acquiring and producing quality software products are not supported by the endless flow of new international standards, legislation and user requirements. In order to clarify the current situation for everybody concerned with software quality, and especially those interested in usability, there is a need for a new review and evaluation of the various strands that contribute to software quality. By way of review this paper recalls the original software quality factors which were defined twenty years ago by McCall et al. and presents a methodical analysis and synthesis of three …
Software Quality: Definitions And Strategic Issues, Ronan Fitzpatrick
Software Quality: Definitions And Strategic Issues, Ronan Fitzpatrick
Reports
This paper contains two sections relating to software quality issues. First, the various definitions of software quality are examined and an alternative suggested. It continues with a review of the quality model as defined by McCall, Richards and Walters in 1977 and mentions the later model of Boëhm published in 1978. Each of McCall's quality factors is reviewed and the extent to which they still apply in the late 1990s is commented on. The factors include, integrity, reliability, usability, accuracy, efficiency, maintainability, testability, flexibility,interface facility (interoperability), re-usability and transferability (portability). They are subdivided into external and internal quality factors. Interrelationships …
