A key task is setting up a PMO services maturity model, which is a structured way to measure how well each PMO service is performing today, define what better performance looks like, and guide a step-by-step improvement roadmap. The central decision is whether to develop a custom model or adopt an existing one.
Adopting means using an established framework. Options include PMI's OPM (Organizational Project Management) approach, which grew out of OPM3, as well as AXELOS P3M3, CMMI, Kerzner's PMMM, and PMO-specific models such as the PMO Maturity Cube. The benefits are credibility, proven level definitions (often five stages, from ad hoc to optimized), ready-made assessment tools, and the ability to benchmark against other organizations. The drawbacks are that these models can be generic, costly to license or certify, and poorly matched to the PMO's actual service catalog, culture, or strategic priorities.
Developing means building a model tailored to the PMO's own services, such as governance, methodology, reporting, resource management, training, and portfolio support. The PMO defines maturity levels and observable criteria for each service, aligns them with stakeholder expectations and organizational strategy, and links them to PMO value metrics. A custom model fits the context closely and builds stakeholder ownership. However, it takes more time and expertise, offers limited external benchmarking, and may be seen as less objective.
Many PMOs choose a hybrid: they adopt a recognized framework as a backbone and adapt its dimensions and criteria to their service portfolio. Whichever path is chosen, the PMO should baseline its current maturity, set target levels based on business need rather than pursuing the highest level by default, prioritize gaps, and reassess periodically. Results should be communicated to sponsors so the model drives real improvement and shows the PMO's growing contribution to organizational value.
PMO Services Maturity Model: Develop or Adopt (PMI-PMOCP Guide)
Overview Within the PMI-PMOCP domain of PMO Enhancement and Effectiveness, one key decision a PMO leader faces is how to measure and improve the maturity of the services the PMO delivers. The leader can adopt an existing maturity model or develop a custom one, often by tailoring an established model. This guide explains why the decision matters, what a PMO services maturity model is, how the develop-or-adopt process works, and how to answer exam questions on the topic.
Why It Is Important Credibility and value demonstration: PMOs are often questioned about their value. A maturity model gives an objective, repeatable way to show where services stand today and how they improve over time. Prioritized improvement: Without a model, improvement efforts tend to be scattered. A maturity model highlights the gaps that matter most to stakeholders and strategy. Alignment with business strategy: Maturity is not a goal in itself. The right model links PMO service capability to organizational outcomes such as delivery predictability, benefits realization and strategic execution. Common language: Executives, sponsors and PMO staff gain shared terms for describing capability levels. Sustainability: Periodic reassessment builds continuous improvement into the PMO operating model. Risk of a wrong choice: An ill-fitting model wastes money, creates assessment fatigue, and can push the PMO toward bureaucracy instead of value.
What It Is A PMO services maturity model is a structured framework that describes progressive levels of capability for the services a PMO provides. Typical services include: - portfolio management - governance - methodology support - resource management - reporting - training and capability building - benefits management
Most models use about five levels, similar to CMMI-style staging: 1. Initial/Ad hoc 2. Repeatable/Defined at project level 3. Defined/Standardized organization-wide 4. Managed/Measured 5. Optimizing/Continuously improving
Well-known external models include: - PMI's OPM3, now evolved into organizational project management maturity concepts - P3M3 (Portfolio, Programme and Project Management Maturity Model) - CMMI - Kerzner's Project Management Maturity Model - PMO-specific value or competency frameworks, such as those promoted by PMO communities
Adopt means using an established, recognized model largely as is. Develop means building a custom model, usually by tailoring or combining elements of existing models, to fit the organization's specific PMO services, culture and strategy.
How It Works: The Develop-or-Adopt Decision Process 1. Clarify the purpose. Decide why you are measuring maturity. Common reasons are benchmarking against industry, guiding internal improvement, justifying investment, or meeting regulatory or client requirements. Purpose drives the choice. 2. Define the PMO service catalog. You cannot measure the maturity of services you have not defined. List the services, their customers and their expected outcomes. 3. Engage stakeholders. Identify what executives, sponsors, project managers and PMO staff value. A model that does not reflect stakeholder priorities will not be accepted. 4. Evaluate available models against criteria. Useful criteria include: - fit with the PMO's services and mandate - industry recognition and benchmarking ability - cost (licensing, certified assessors, training) - complexity and assessment effort - cultural fit and organizational size - support for agile or hybrid ways of working - availability of tools and guidance
5. Make the decision. Adopt when: - external benchmarking or certification is needed - the organization lacks time or expertise to build a model - credibility with executives or clients depends on a recognized standard - the PMO's scope matches the model's scope well
Develop or tailor when: - the PMO offers unique services not covered by standard models - the organization's culture, size or delivery approach differs significantly - the cost or complexity of a formal model is disproportionate - the goal is internal improvement rather than external comparison
Hybrid (most common best practice): Start from a recognized model and tailor dimensions, levels and criteria to the PMO's service catalog and strategic goals. This keeps credibility while improving fit.
6. Define dimensions, levels and evidence criteria. - Describe each service dimension at each level. - Specify observable evidence, such as artifacts, metrics and behaviors. - Use objective criteria to reduce subjectivity.
7. Baseline assessment. Conduct the initial assessment through surveys, interviews, artifact reviews and workshops. Validate the results with stakeholders. 8. Set target maturity. Targets should be driven by business need. Not every service needs level 5. Over-maturing low-value services wastes resources. 9. Build a roadmap. Prioritize gap-closing initiatives by value, effort and risk. Integrate them into the PMO improvement plan. 10. Reassess and evolve. Reassess periodically, report progress to stakeholders, and update the model itself as the PMO's mandate changes.
Key Principles to Remember - Maturity serves value. The aim is better business outcomes, not a higher score. - Tailoring is expected. PMI consistently emphasizes fit for purpose. - Stakeholder involvement drives acceptance. - Measurement should be evidence-based and repeatable. - Maturity targets differ by service and by organization. - The model is a living tool and should be reviewed as strategy shifts.
Exam Tips: Answering Questions on PMO Services Maturity Model: Develop or Adopt 1. Look for the purpose first. If the scenario mentions benchmarking against peers, client requirements or certification, lean toward adopting a recognized model. If it stresses unique services, culture or internal improvement, lean toward developing or tailoring. 2. Prefer tailoring over rigid adoption. When answers include "adopt an industry model and tailor it to the PMO's services and strategy," that is often the best choice. PMI favors fit-for-purpose approaches. 3. Stakeholders before solutions. Answers that start with understanding stakeholder needs, the PMO mandate or the service catalog usually beat answers that jump straight to selecting a tool or running an assessment. 4. Reject maturity for its own sake. Be wary of options that push every service to the highest level or treat the score as the goal. Correct answers tie target maturity to business value. 5. Baseline before roadmap. The logical sequence is: purpose, then model selection, then baseline assessment, then target setting, then roadmap, then reassessment. Choose answers that respect this order. 6. Watch for cost and complexity cues. A small or new PMO with limited resources is unlikely to benefit from a heavy, expensive formal assessment. A lightweight or tailored model is better. 7. Evidence-based assessment. Prefer answers using objective evidence and multiple data sources over self-reported opinions alone. 8. Continuous improvement. Correct answers often include periodic reassessment and updating the model as the organization evolves. 9. Communicate results. Sharing assessment outcomes and the roadmap with sponsors builds support. Hiding poor results is never correct. 10. Eliminate extremes. Options such as "always build your own" or "never modify a standard model" are usually wrong. Context determines the answer.
Sample Question A newly appointed PMO director must assess the PMO's service maturity. Executives want to compare performance with industry peers, but the PMO provides several services unique to the company. What should the director do first? A) Build a completely custom model B) Adopt a recognized maturity model and tailor it to include the unique services C) Skip assessment and focus on delivery D) Purchase the most comprehensive model and apply it unchanged
Answer: B. It balances benchmarking credibility with fit to the PMO's unique services.
Summary The develop-or-adopt decision for a PMO services maturity model depends on purpose, stakeholder needs, service scope, resources and the need for external comparison. Adopting offers credibility and benchmarking. Developing offers fit. Tailoring a recognized model often delivers both. On the exam, choose answers that are value-driven, stakeholder-informed, evidence-based, properly sequenced and focused on continuous improvement.
