Abstract

A stochastic model of dependability of computer systems in Zimbabwe G. Kabanda Central Computing Services, P.O. Box CY704, Causeway, Harare, Zimbabwe ABSTRACT A theoretical approach to evaluation leads to the hypothesis that human-computer interaction is affected by personality, influencing types of dialogue, preferred methods for providing help, etc. A practical framework suggests that evaluation is an integral part of the design and that the iterative use of the evaluation techniques throughout the conceptualisation, design, implementation, and post-implementation stages would satisfy user needs and fulfil usability goals. Evaluation is crucial to the improvement of the design and performance of a computer system, ascertaining the value of the software, legalising its use and promotion of such systems. The aim of the paper was to determine and utilize design evaluation techniques in the software development process. In this study
