Effective project governance and project management are fundamental mechanisms of ensuring that projects are successfully delivered within the project timelines.  It involves a multifaceted set of relationships with stakeholders in an organization. Project governance provides a structure through which project related objectives are set, and the means of accomplishing those are documented and prioritized. In summary, the purpose of this paper was to provide a comprehensive understanding through documentation and re- search on the impact of project governance impact on project delivery. The research also intends to increase awareness of the inherent risks associated with poor implementation of project governance which leads to poor project delivery and consequently project failures. A mixed-method research approach was under- taken where data was gathered through primary and secondary sources. A questionnaire was circulated in one of the branches in Johannesburg Enterprise Project Management Office, to a population of 58 staff in EPMO comprising of Head of Department, 6 senior project managers and 51 junior staff members. Only 30 responses were received and on average respondents indicated that there is an adverse impact on project delivery due to poor project governance. This has been evidenced by the operational inconsistencies sourced from the findings.
