Critical Factors Affecting the Usability of Igbinedion University Online Portal System

Usability is an important aspect of software products. However, in practice not much attention is given to this issue during software evaluation. Software evaluators often do not have the knowledge, instruments and /or time available to hand le usability issues. Nevertheless, evaluating usability of any software product most especially from the end users view gives an in-depth analysis of the product which could be used to either enhance the product or develop it entirely. This study introduces a Software Usability Evaluation Technique that can be used to evaluate the critical factors affecting the usability of a portal system, using Igbinedion University Online Portal System as a case study. The technique consists of a web-based questionnaire that is supported by an extensive database and embedded in an effective analysis and reporting tool called SPSS (Statistical Packages for Social Sciences). This approach consists only of methods to measure software usability from the users’ perspective. Using this approach, software product can be evaluated in a consistent and objective manner.
