It is important that an organization selects the right projects and carefully manages and governs them to deliver their intended benefits. This paper will describe a model for Organizational Project Management (OPM) to help organizations to do that. OPM is the integration of all project management-related activities of an organization linking strategic decisions (where the project management-related activities are to be carried out) with business decisions (portfolio management and benefits realization) with their management (program and project management) and their governance at both the strategic and project levels. This paper will describe a seven-layered model of OPM with its 22 elements – spanning from the organizational level to the individual project level – derived by the authors using academic literature and their own experience in managing projects.
