Modelling Your Maturity, P3M3, CMMI and/or OPM3 [P052]
Successful organisations apply project management
processes effectively and consistently. Three well defined
‘maturity models’ are internationally available,
which is the most appropriate to use?
P3M3 (Portfolio, Programme & Project Management Maturity Model) is the newest model, it has been developed by the Office of Government Commerce (OGC) in the UK to support its Gateway, MSP and PRINCE2 methodologies. P3M3 is modelled on the old CMM. The new Capability Maturity Model® Integration (CMMI®) was developed by the Software Engineering Institute (SEI) to assist organisations to improve their processes for developing and maintaining the products and services of the organisation. The Organizational Project Management Maturity Model (OPM3®) was developed by the Project Management Institute (PMI) to assist organisations to improve their capabilities for managing projects, programs and portfolios, leading to business improvement. OPM3 has been developed from PMI’s standards: the Project Management Body of Knowledge (PMBOK®) for projects, and the standards for Program Management and Portfolio Management.
As projects, programs and portfolios are generally focused on developing and maintaining products and services, the goals for P3M3, CMMI and OPM3 should be aligned. Potential adopters and customers of PMI Standards had questions related to the differences between CMMI, OPM3 and the PMBOK. More recently P3M3 has been added as a third option. This paper will compare and contrast the three standards and identify their strengths and weaknesses.
