Types of ERP Systems and Their Impacts on the Supply Chains in the Humanitarian and Private Sectors

(1) Background: This paper explores different ERP systems used in the supply chains of humanitarian and private sectors and their key impacts on supply chain performance. The study examined 19 potential impacts from the published literature from 2015 to 2020 and investigated whether they are equally relevant in the global private and humanitarian sectors. (2) Methods: An anonymous online questionnaire was used and advertised on different social media websites. Fifty humanitarian supply chain professionals and 53 private sector professionals completed the questionnaire. A descriptive statistic cross-tabulation analysis was used to show the differences or similarities in the collected responses, and a Mann–Whitney Test was used to test the research hypotheses. (3) Results: The findings highlighted the key impacts of ERP systems on supply chain performance and confirmed that these impacts are similar in both sectors. Additionally, the humanitarian sector prefers to implement custom-made ERPs, whereas the private sector purchases ready-to-use products. (4) Conclusions: The reviewed literature did not show studies conducting such a comparative study. The results provide a better understanding of the types of ERP systems and their impacts on supply chain operations within the two examined sectors.
