PMO survey and the PDCA

The PDCA (Plan do check act) cycle is a great tool in deploying any process. Simply put, the PMOs critical role is deploying project management best practices for value delivery. In this context, 

• Plan - Training and competence building + staffing / resource planning for programs (This includes involvement of PMO in strategic planning)
• Do - Support for greater functions and projects
• Check - Metrics and tracking
• Act - Continuous improvement

As PMOs mature (Over 3~5 years) , the check and act become more critical and important. For nascent PMOs, the first 2 are important. I think, this has come out very well in this excellent survey - PMO survey and webcast
