This paper attempts to identify probable structure underlying myriad PMO functions. The scope of the paper is confined to 27 PMO functions as reported in a white paper prepared for Project Management Institute (PMI) on global analysis of the current state of practice of multi-project PMOs. This white paper is based on a global survey in which 500 PMOs participated. A probable structure has profound implications for project management theory and practice. A technique called Interpretive Structural Modeling (ISM) has been used for this purpose. The paper provides an interpretation of these structures within program management.
