This document summarizes research on failure factors of ERP (enterprise resource planning) projects in Iranian manufacturing industries. Through interviews with ERP experts and a questionnaire sent to IT, operations, and production employees, the researchers identified the most significant failure factors. The top four factors were lack of sufficient training, lack of management support, lack of financial support, and employee resistance to change. Less than 40% saw lack of experience as a major factor. Most respondents felt that training could help overcome inexperience. The researchers concluded these human and organizational factors were more important causes of ERP project failures in Iran than technical complications.
