Evaluating and Prioritizing Barriers for Sustainable E-Learning Using Analytic Hierarchy Process-Group Decision Making

E-Learning is a popular computer-based teaching–learning system that has been rapidly gaining global attention during and post COVID-19. The leaping changes in digital technology have enabled to become more effective recent years. It offers freedom from restrictions caused by geographical boundaries provides time flexibility the process. Apart its numerous advantages, success of depends upon many critical factors (CSFs) barriers. If barriers lie way successful implementation are not addressed diligently, it will limit success. revealed through past research these serious threats need immediate their redressal. This paper attempts reveal sixteen under four different dimensions going comprehensive review literature engaging decision makers. Furthermore, uses Analytic Hierarchy Process-Group Decision Making (AHP-GDM) methodology evaluate prioritize them. results obtained show related Institutional Management Dimension (BIMD), Infrastructure Technological (BITD), Student (BSD), Instructor (BID) pose greatest challenges E-Learning. AHP-GDM methodologies comparative relationship among as BIMD > BITD BSD BID further quantify negative effects 46.35%, 29.88%, 12.30%, 11.4%, respectively, on systems (‘>’ indicates challenges).
