This is a group or department within a business, agency or enterprise that defines and maintains standards for project management within the organization. The PMO strives to standardize and introduce economies of repetition in the execution of projects. In a contingent program, a PMO will be tasked with handling the day to day interactions between engagement managers, staffing suppliers and contingent resources as well as identifying opportunities for optimization of the program based on industry best practices. While most PMOs are provided by third-party managed serviced providers, many companies utilize internal teams as their PMO.
