Predicting the adoption of e-procurement in construction project delivery in Sub-Saharan Africa: an application of UTAUT2.

Purpose: The substantial benefits of e-procurement to organizations and institutions have, over the past two decades, become central to supply chain management. This study aims to identify the factors that facilitate the adoption of e-procurement system using modified Unified Theory of Acceptance and Use of Technology (UTAUT2). Design/methodology/approach: Using a quantitative approach, the factors identified in the UTAUT2 are operationalized and examined carefully. The investigation has been conducted using a survey questionnaire. The data set has been obtained from 205 construction professionals in Ghana. Findings: The research evinced that the decision by individuals to adopt e-procurement is mainly influenced by performance expectancy and social influence. By implication, the study found out that the respondents are more likely to adopt e-procurement if it is seen to be user-friendly and useful, and when they have a community of people supporting its use. Overall, the findings suggest that the model can stimulate a high adoption and intention to use e-procurement technologies, given its good predictive potential and robustness. Practical implications: The structures uncovered in the study show that not all UTAUT2 factors are applicable within the study area. The findings provide a good backdrop in the development of policy and a roadmap for e-procurement implementation in Ghana. This is particularly useful for system development and implementation purposes for government agencies, contracting organizations, professionals and users of e-procurement technologies. Originality/value: The original contribution and value of the paper is the use of UTAUT2 to provide evidence on their significance to e-procurement adoption among construction professionals.
