Abstract

A quality model links together and defines the various software metrics and measurement techniques that an organisation uses which when measured, the approach taken must be sufficiently general for hybrid hardware and software systems. In this work software quality factors that should be taken into account in very large information systems will be considered. Such systems will require a high degree of parallelism and will involve a large number of processing elements. We start by identifying the metrics and measurement approaches that can be used. Many of the quality factors would be applied in similar way for sequential and paralleldistributed architectures, however a number of factors will be investigated which are relevant to the parallel class. In such a system many elements can fail which can have major impact on the system's performance, and therefore it affects the costbenefit factors. Portability and usability are other major problems that need to be taken into account when considering all the relevant factors that affect quality for such environments.

Abstract

The objective of this investigation was to determine whether the analytical hierarchy process algorithm is suitable for the evaluation of software by evaluators with little Information Technology experience. The scope of the research was the evaluation of two free and open source e‑learning systems at the Open University of Tanzania using 33 stakeholders with diverse levels of Information Technology experience. Both quantitative and qualitative research methods were used. The qualitative methods comprised participative observation and interviews. Questionnaires and the analytical hierarchy process, a multiple‑criteria decision‑ making algorithm, represented the quantitative methods. The results showed that of the two e‑learning systems evaluated, Moodle was preferred over ATutor. Furthermore it was found that the analytical hierarchy process algorithm is appropriate for the evaluation of software in a situation where Information Technology experience is limited. It is anticipated that the paper contributes to the theory and practise of decision making in developing countries such as Tanzania.
