Project Management Maturity Explained and Why It Matters

PMOs and Project Management Maturity

PMOs are integrators. They bridge organisational silos and bring projects, programmes, and portfolios together so delivery operates as a connected ecosystem rather than a collection of isolated initiatives.

This is achieved by balancing three essential variables within P3M governance: people, practices, and tools. Together, these elements enable the PMO to support effective governance, consistency, and visibility across delivery.

This balance does not exist in isolation. It is heavily influenced by leadership, particularly the role of the Sponsor directing projects, programmes, or portfolios. Sponsorship is widely recognised as one of the key enablers of success and one of the most common reasons for failure.

As organisations mature, the role of the PMO often evolves. Strengthening PMO maturity requires clarity of purpose, alignment to organisational goals, and an operating model that reflects current and future needs. This is explored further in our blog on strengthening PMO maturity.

Achieving Value Through Governance

To identify current maturity and determine where to focus improvement efforts, it is important to assess how well governance mechanisms are defined, understood, and applied. This includes methodologies, decision-making routes, approval mechanisms such as stage gates, and escalation paths.

For PMOs, governance mechanics alone are not enough. A deeper understanding is required of how governance functions in practice, including:

• Roles and responsibilities of governance bodies
• How those bodies interact with the PMO
• The PMO’s remit, objectives, and authority
• Availability and engagement of Sponsors
• Use of KPIs to measure PMO performance and value

For organisations at an earlier stage of maturity, the priority is often establishing these foundations. Practical guidance on building early capability is covered in our article on beginning your maturity journey with a PMO solution.

Reaching Project Management Maturity

Different maturity assessments define enablers and focus areas in different ways. One of the most widely recognised frameworks is the P3M3 maturity model, which assesses maturity across projects, programmes, and portfolios through a structured, evidence-based approach.

If you are unfamiliar with the framework, our article on what the P3M3 maturity model is provides a clear overview of its structure and purpose.

Most maturity assessments map capability on a scale from Level 0 to Level 5. As organisations progress, practices become more consistent, data-driven, and strategically aligned. Understanding how maturity is assessed can help organisations plan improvement activities more effectively, which is discussed further in our article on PPM maturity assessments.

Formal assessments are best completed by independent providers. Independent benchmarking, such as a PPM and PMO maturity assessment and benchmark, provides clarity on current capability and a practical roadmap for improvement.

Practical Steps to Improve Project Management Maturity

Even before a formal maturity assessment, there are practical actions organisations can take to strengthen maturity. These steps help establish foundations and prepare teams for progression.

1) Appropriate Methodology

Many organisations struggle with methodologies that are overly complex or difficult to apply consistently. When methods are too rigid, teams often find workarounds instead of following them.

To make methodologies more effective and usable:

• Define clear minimum standards that apply to all projects
• Allow tailoring based on project size, risk, and complexity
• Separate mandatory elements from optional guidance
• Use plain language that reflects how teams actually work
• Keep stage gates focused on decisions, not documentation volume

2) Accessible Resources

PMOs often invest heavily in comprehensive templates without considering effort versus reward. When documentation becomes too complex, adoption drops and value is lost.

To improve accessibility and uptake of resources:

• Reduce template length and remove duplicated content
• Structure documents around clear questions and prompts
• Focus on decision-making rather than information capture
• Design templates for real workflows, not ideal scenarios
• Regularly review usage and retire templates that add little value

3) Basic Training

Foundational project management training delivers significant organisational value. It builds core skills and creates a shared understanding of good practice across teams.

To maximise the impact of training:

• Focus on practical application, not theory alone
• Align training content to your methodology and governance
• Provide training at the point of need, not just once
• Include sponsors and managers, not only project managers
• Reinforce learning through coaching and on-the-job support

4) Schedule or Plan Templates

Standard planning templates provide structure and consistency across projects while reducing the need to recreate plans from scratch.

To make planning templates effective:

• Include only the information required to manage and govern work
• Standardise terminology and definitions across templates
• Provide examples of completed plans as guidance
• Ensure templates scale appropriately for different project types
• Embed templates into tools rather than relying on standalone documents

5) The PMO Matters

PMOs are established for different reasons, including strategy enablement, delivery support, centres of excellence, and assurance. There is no single correct PMO model.

To ensure the PMO supports maturity growth:

• Clearly define the PMO’s purpose and value proposition
• Align PMO services to organisational priorities
• Review and adjust the PMO model as maturity evolves
• Ensure the PMO has appropriate authority and sponsorship
• Measure PMO performance using outcomes, not activity

Committing to Maturity

Project management maturity assessment and improvement are not one-off activities. They are iterative processes that provide insight into strengths, gaps, and opportunities for growth.

Organisations must be ready for assessment and open to challenge and change. Communicating the benefits of maturity improvement helps build support and commitment across stakeholders.

Where a formal framework is required, specialist support aligned to the AXELOS P3M3 maturity model can help organisations apply best practice in a proportionate and practical way.

Benefits of Doing a Project Maturity Assessment

Higher Proactivity
Understanding current maturity helps teams identify gaps early and move from reactive delivery to proactive improvement.

Increased Success
As maturity improves, organisations become better at anticipating challenges and delivering consistent outcomes, often leading to improved return on investment.

Customer Experience
Greater consistency and confidence in delivery improves trust with both internal and external customers and supports stronger supplier relationships.

Enhanced Discipline
Clear maturity targets and roadmaps improve focus, accountability, and disciplined ways of working.

Levels of Maturity and Achieving Them

Most maturity models define five levels, broadly aligned with the P3M3 model:

• Initial: Awareness exists, but practices rely on individuals
• Defined: Processes are documented but inconsistently applied
• Standardised: Consistent organisational ways of working
• Managed: Data is analysed to drive improvement
• Optimised: Continuous improvement informs strategic decisions

There is no universally correct maturity level. Many organisations aim for consistency rather than optimisation, which alone delivers significant value. Understanding how to progress between levels is covered in how to navigate the P3M3 maturity levels:

Strategy and Maturity Work Better Together

Organisational strategies often change, creating challenges for delivery. Linking maturity improvement directly to strategic objectives helps prioritise effort, justify investment, and measure progress in meaningful ways.

When maturity growth supports strategy, organisations are better positioned to deliver change successfully and sustainably.

Closing Thoughts

Project management maturity is a journey rather than a destination. Organisations that benefit most treat maturity as a practical improvement cycle grounded in evidence and aligned to strategy. With the right balance of people, processes, and tools, PMOs play a central role in enabling consistent delivery and long-term value.
