Abstract:
e-Procurement deals with electronic means to carryout construction procurement
processes, such as tendering and procurement for projects (Ibem & Laryea, 2017), and it
entails crucial processes for initiating and executing projects (Costa & Tavares, 2013). e
Procurement improves efficiency in resource utilization and waste reduction by decreasing
paperwork, increasing transparency, and minimizing errors (Singh & Chan, 2022). Several
studies have been conducted to identify barriers to e-Procurement adoption but developing
a robust framework to explore interrelationships between barriers is, however,
comparatively lacking. By supporting the use of mixed-methods for Total Interpretive
Structure Model Framework development to explore interrelationships, this study adds to
the body of literature on e-Procurement. Previous studies have shown that the adoption of
electronic procurement practices has high implementation challenges in developing
countries. To close this gap, the paper first conducts a systematic review of the literature
on e-Procurement barriers. Then utilizes Delphi Technique to formulate survey based on
expert’s opinion; ranks barriers as perceived by Contractors and Procuring Agencies
respectively on basis of Relative Importance Index (RII) using survey conducted. Further
it carries out Factor Analysis (EFA & CFA) to demonstrate the statistical validity of
constructs to be utilized in finally developing the framework on e-Procurement barriers
using TISM, MICMAC analysis.
