PMI defines a project management office (PMO) as a management structure that standardizes the project-related governance processes and facilitates the sharing of resources, methodologies, tools, and techniques. According to PMI, there are several types of PMO structures in organizations, each varying in the degree of control and influence they have on projects within the organization, such as:
- Supportive PMOs provide a consultative role to projects by supplying templates, best practices, training, access to information and lessons learned from other projects. The degree of control provided by the PMO is low.
- Controlling PMOs provide support and require compliance through various means. Compliance may involve adopting project management frameworks or methodologies, using specific templates, forms and tools, or conformance to governance. The degree of control provided by the PMO is moderate.
- Directive PMOs take control of the projects by directly managing the projects. The degree of control provided by the PMO is high.
