- ItemEvaluation of Transwerk Risk Management Information System(Stellenbosch : Stellenbosch University, 2005-03) Mpanza, Brian Vusumuzi; Botha, Daniel F.; University of Stellenbosch. Faculty of Arts and Social Sciences. Dept. of Information Science.ENGLISH ABSTRACT: In the last decade, the use of computers has proliferated the industrial arena in South Africa. Due to frequent changes in computer programs and developments in the computing field, users have often been adversely affected. Users experience problems with computer programs that are not user friendly. Usability is about satisfying the user needs by allowing the user to accomplish their goals quickly, efficiently and easily. Thus it 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 be used to test and evaluate usability in the Transwerk Risk Management Information System, that is Computer Assisted Risk Management Systems (CARMS). I first consider the difference between unusable and usable programs. Usability properties are then identified including properties enhancing effectiveness, efficiency, flexibility, laemability and attitude of the computer program. The CARMS components or modules and users were identified. Usability problems were identified that cause the users to be selective and discouraged to use other components of CARMS. To further verified and address the usability problems identified, the whole program needs to be tested and evaluated. The methodology was laid for how to do usability testing and evaluation in computer program that are currently in use like CARMS. 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.
