In this paper, we evaluate the reasons for the failure of information systems in public universities. To that end, we start by presenting a hierarchical structure of criteria after reviewing related studies, and dividing the criteria into the categories of project management, organizational management, humanrelated, organizational and technical. To assess the weight of the criteria in the proposed framework, we collect the opinions of a sample of information technology experts working in different public universities in Iran, using an online questionnaire that is based on the best-worst method (BWM). By analyzing the weight of the criteria, we can reveal that misfit of information systems software (closely followed by lack of top management support and unsuccessful monitoring and measurement) has the greatest impact on the failure of information systems in the public universities of Iran. The methodology proposed in this paper can be used in other countries facing the same problem.
