Information technology (IT) acceptance studies pay much attention to issues of significance in assessing the contributions of variables explaining IT usage for decision-making in organizations. Davis’ Technology Acceptance Model (TAM) states that Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) are the two factors that govern the adoption and use of information technology. Actual System Use (behavior) consists of the number of times of systems use. The author conducted a survey of 31 organizations in KwaZulu/Natal, a region in South Africa, which implemented an Executive Information System (EIS). A validated survey instrument was administered to an EIS stakeholder in each organization surveyed. This paper reports on the PU, PEOU, and Actual System Use constructs for organizations surveyed in South Africa.
