However, PMOs face significant challenges in clearly defining their roles and responsibilities due to the variety of potential functions that can be assigned to them. This study presents a systematic analysis of PMO typologies, types, and respective functions, providing an in-depth understanding of the dynamic PMO role. We found 16 typologies and 60 PMO types in the literature, showing that PMOs are complex and evolving entities that can assume various forms and organizational responsibilities.18626969engproject management office (PMO)organizational project managementPMO typologyPMO typePMO functionBusiness and International ManagementStrategy and ManagementManagement of Technology and InnovationSDG 8 - Decent Work and Economic Growthreview10.1177/87569728241297899https://www.scopus.com/pages/publications/85210083617https://www.webofscience.com/wos/woscc/full-record/WOS:001356692000001
