This research aims to explore factors responsible for successful implementation of ERP systems in Indian organizations. The paper also aims to explore the similarities and differences in ERP system adoption between locally-owned and multinational companies in India. The data was collected from 56 project managers and business analysts with ERP expertise from both locally-owned Indian and multinational companies. The findings suggest that Business Plan and Vision, Project Management and Top Management Support were perceived as the three most important factors responsible for successful implementation. The result revealed no significant differences between Indian and multinational companies, hence indicating that both types of firms undertake the ERP implementations in the same manner.
