Adoption intentions of electronic procurement among public sector organisations (PSOs) in Ghana: emerging economy perspective

Purpose - Electronic government procurement is an important platform that promotes efficient, transparent, competitive and agile delivery of procurement activities in public sector organisations. Implementing units who play a major role exhibits different attitude towards new technology. The purpose of this paper is to assess if there is any significant difference between optimistic and discomfort implementing units in relation to the implementation and intention to use the Ghana Electronic Procurement System (GHANEPS). Design/methodology/approach - Technology Readiness, Technology Acceptance and Unified Theory of Acceptance and Use of Technology and Diffusion Innovation Theory constituted the theoretical foundation. Guided by a cross sectional survey design, quantitative data from a sample of 181 procurement officers was collected using structured questionnaires. The hypothesised relationships were analysed using partial least squares structural equation modelling (PLS-SEM). Findings - Although there were some observable differences, the bootstrap results show that the difference was not significant, implying that these two groups do not differ much about the GHANEPS introduction and implementation. This is justifiable in the case of Ghana because public policies are made by top officials, and those in the grassroot or implementation domain have no choice but to act accordingly. Research limitations/implications - This study focused on metropolitan, municipal, district assemblies, public hospitals, tertiary institutions and senior high schools. Practical implications - The study contributes to the critical antecedents for electronic procurement implementation and public sector management literature. It provides public institutions and practitioners with empirical evidence on how beliefs and perceptions of implementing units about electronic public procurement has some influence on attitude towards usage and intention to use. Positive attitudes and perceptions of the public procurement officers can be reinforced through adequate training and awareness creation. Social implications - This study outcomes can serve as philosophical underpinnings for societal development. Originality/value - This study used a multi-group analysis to examine if there is any significant difference between these two categories of implementing units (optimistic group and discomfort group) in relation to facilitating conditions, personal innovativeness, perceived usefulness, perceived ease of use and ultimately to attitude and intention to use GHANEPS.
