Acceptance of E-procurement in Organisations: Using Structural Equation Modeling (SEM)

This research is concerned with the development of a realistic model for e-procurement adoption by organizations and groups observing the Rules of Islamic Sharia (RIS). This model is intended to be based on the behavioural control, subjective norms, and the recognition of the benefits and risks of eprocurement adoption. The developed model, "E-Procurement Adoption Model" (E-PAM), combined and extended two existing models previously used for information technology adoption. Central to the design of the E-PAM is the principle that a realistic model should consider all relevant psychological, social, cultural, demography, and religious factors. The mediating components "mediators" that determine the final model are thus determined by the specific aforementioned factors about of on to the development of an e-procurement approach in the context of the Rules of Islamic Sharia. Therefore, in the design of the research model, factors including perceived usefulness, perceived ease of use, organizational facilitators, organisational leadership, critical success factors, challenges, barriers, and benefits were taken into account. These factors in turn gave rise to the two mediating components of 'Attitude' and 'Rules of Islamic Sharia'.
