This study investigated the barriers to the uptake of e-Procurement by organizations in the NBI. The survey research strategy was adopted due to the nature of the research questions and the fact that past studies in Canada [12], the UK [13 and 14] and South Africa [1] adopted similar strategy. In view of this, the data used were collected from both primary and secondary sources. Whereas the secondary data were derived from the review of published literature on the subject matter, the primary data came from the administration of structured questionnaire. The study reported here was part of a larger study conducted to investigate the use of e-Procurement in the NBI. Therefore, the questionnaire used was designed by the researchers and had four sections. Section 1 focused on the professional roles of the participants and their organizations. Section 2 had questions on the different Internet-based technologies and tools used in the procurement of building works, services, equipment and materials. Section 3 contained questions relating to the factors considered important in the decision by
organizations in the NBI to adopt e-Procurement. The last section of the questionnaire was used to collect data on the factors militating against the uptake and optimization of the benefits of e- Procurement in the NBI. The participants were specifically asked to rate 26 factors in order of their adverse impact on the uptake of e-Procurement by the organizations based on 5-Likert like scale of 1= “Has No Significant Effect”; 2 = “Has Very Little Effect”; 3= “Undecided” 4 = “Has Significant Effect” 5 = “Has The Most Significant Effect”. The 26 factors investigated were grouped into three main sub-groups, namely, internal barriers, perception of the risk associated with e- Procurement use and external barriers (Figure 1) as previously identified in the existing studies [2; 23;24 and Table 1]. It is important to state that the data presented in this paper are those extracted from the participants using Sections 1 and 4 of the questionnaire instrument. Before the main research was conducted, the questionnaire instrument was pre-tested in a pilot survey carried out in Lagos in April 2015. Findings of the pilot survey helped the researchers in fine- tuning the questions in the questionnaire. The main
