This study identifies the perceived benefits of Enterprise Architecture (EA) among business stakeholders who are aware of EA but are not specialists in the field of ICT, and proposes a clearly differentiated and comprehensive cluster of stakeholder groups based on these perceptions. It provides an understanding of the benefits of EA from the perspective of business beneficiaries, not the perspective of its practitioners.The study was conducted using Q-methodology, which was developed specifically to uncover subjective perceptions and preferences. Q-methodology correlates people in respect of their perception of a sample of tests, and is particularly useful in bridging the sharp dichotomy between qualitative and quantitative methodologies.

Students in the open-distance and electronic learning (ODeL) environment often work in isolation and face challenges in accessing knowledge resources, especially when conducting research. To support these students in succeeding with their studies, the learning management system (LMS) needs to be usable; this implies the attributes of effectiveness, efficiency and user satisfaction. The purpose of this study is to propose usability guidelines specifically focused on the requirements for a learning management system in the context of ODeL honours research projects. The study is novel in exploring the supervisors' view of the usability requirements of the LMS. Based on a pragmatic worldview, this study is guided by the design science research (DSR) methodology. The initial set of usability requirements was abstracted from the literature and used as the basis for the LMS evaluation. Usability testing of the LMS was followed by heuristic evaluation, post-test questionnaire and interviews. All evaluations were done with the supervisors as participants. The contribution of the study is the refined usability guidelines based on the triangulation of the findings from the different usability evaluations conducted on the same ODeL LMS.

The 2020 health pandemic brought renewed interest in using learning management systems (LMSs) to deliver educational services as routinely done in open distance and electronic learning (ODeL) environments. LMSs usability has been researched but the lecturers' perspective remains unexplored. The purpose of this study was to propose validated usability guidelines for an LMS in an ODeL context. A set of usability requirements was abstracted from the literature and used as the basis for a heuristic evaluation (HE) of the institution's LMS. These results of the HE was triangulated with three other usability evaluation methods including usability testing with eye tracking, a post-test system usability scale (SUS) questionnaire and interviews. The primary contribution is the validated usability requirements for ODeL LMSs based on the lecturers' perspective. A secondary contribution is the triangulation approach to evaluating the guidelines in situ which confirmed HE as a valid evaluation method for LMSs.
