Abstract:
This study compared the usability of three Information and Communication Technology (ICT) network programs in a learning environment. The researcher wanted to establish which program was most adequate from a usability perspective among second-year Information Technology (IT) students at the Central University of Technology (CUT), Free State. The Software Usability Measurement Inventory (SUMI) testing technique can measure software quality from a user perspective. The technique is supported by an extensive reference database to measure a software product’s quality in use and is embedded in an effective analysis and reporting tool called SUMI scorer (SUMISCO). SUMI was applied in a controlled laboratory environment where second-year IT students of the CUT, utilized SUMI as part of their networking subject, System Software 1 (SPG1), to evaluate each of the three ICT network programs. The results, strengths and weaknesses, as well as usability improvements, as identified by SUMISCO, are discussed to determine the best ICT network program from a usability perspective according to SPG1 students.
