Evaluation of Transwerk Risk Management Information System

[摘要] ENGLISH ABSTRACT:In the last decade, the use of computers has proliferated the industrial arena in SouthAfrica. Due to frequent changes in computer programs and developments in thecomputing field, users have often been adversely affected. Users experience problemswith computer programs that are not user friendly. Usability is about satisfying the userneeds by allowing the user to accomplish their goals quickly, efficiently and easily. Thusit is crucial that industries invest in computer programs that offer optimum usability.In this research an attempt is made to provide a framework for methodology that can beused to test and evaluate usability in the Transwerk Risk Management InformationSystem, that is Computer Assisted Risk Management Systems (CARMS). I first considerthe difference between unusable and usable programs. Usability properties are thenidentified including properties enhancing effectiveness, efficiency, flexibility, laemabilityand attitude of the computer program.The CARMS components or modules and users were identified. Usability problems wereidentified that cause the users to be selective and discouraged to use other components ofCARMS. To further verified and address the usability problems identified, the wholeprogram needs to be tested and evaluated. The methodology was laid for how to dousability testing and evaluation in computer program that are currently in use likeCARMS.Benefits and limitations of testing and evaluating usability were detailed in this research.It is recommended that, testing and evaluating usability should be done to prevent errors,dissatisfaction and to improve usability of the CARMS program.
