Abstract-The article presents research results concerning critical success factors in IT projects consisting in ERP, CRM, BI and DM system implementations, completed between 2013 and 2017. The research stems from the need to update knowledge concerning critical success factors in projects completed in commercial enterprises. The research was carried out in medium and large enterprises implementing outsourcing-based projects.
