In project management, organizations often strive to achieve higher levels of maturity in the way they deliver projects, programmes, and portfolios. The Portfolio, Programme, and Project Management Maturity Model (P3M3) provides a framework that helps organizations evaluate their current practices, identify strengths, and uncover areas for improvement.
Unlike single-level models, P3M3 recognizes the different dimensions of maturity and allows organizations to assess them independently across portfolio management, programme management, and project management. Understanding the terminology within this framework is essential for leaders, project managers, business analysts, and stakeholders.
This glossary has been designed to provide clarity, deepen comprehension, and serve as a reference guide with over 100 key terms. Each term plays a crucial role in applying P3M3, from foundational concepts to specific maturity processes.
1. P3M3
The Portfolio, Programme, and Project Management Maturity Model, commonly known as P3M3, is a framework designed to assess organizational maturity in managing change initiatives. It enables structured evaluation across three core domains. Organizations use it to identify strengths and development areas.
2. Portfolio Management
Portfolio management is the centralized process of managing multiple projects and programmes to achieve strategic business goals. In P3M3, this is assessed for its maturity and effectiveness in aligning initiatives with corporate objectives. It helps optimize resource use and prioritize investments.
3. Programme Management
Programme management involves coordinating related projects to deliver outcomes that create organizational benefits. Within P3M3, this discipline evaluates how effectively an organization delivers change through structured programmes. It is critical for benefits realization.
4. Project Management
Project management focuses on delivering specific outputs within defined scope, time, and budget. P3M3 evaluates the processes, governance, and methodologies used for project execution. Higher maturity levels show consistency, predictability, and control in projects.
5. Maturity Model
A maturity model measures the capability of an organization in a structured way. P3M3 uses a five-level maturity model to assess strengths and weaknesses. It provides a roadmap for improvement and benchmarking against industry standards.
6. Level 1 Awareness
Level 1 indicates that processes exist but are largely unstructured, unpredictable, and reactive. At this stage, success relies heavily on individuals rather than organizational practices. Risks are higher, and consistency is low.
7. Level 2 Repeatable
At Level 2, basic processes are repeatable, and some consistency starts to emerge. However, practices are still localized and not yet embedded across the organization. Success depends on specific teams or leaders.
8. Level 3 Defined
Level 3 organizations have documented, standardized processes. Project, programme, and portfolio management practices are embedded in policies. The approach is more predictable, and governance improves significantly.
9. Level 4 Managed
At Level 4, organizations measure and control their processes systematically. Data and metrics guide improvements, making performance more predictable. Risk management and benefits realization are structured and consistent.
10. Level 5 Optimized
The highest maturity level reflects continuous improvement and innovation. Organizations actively refine processes, integrate lessons learned, and embed best practices. They adapt to change quickly and effectively.
11. Assessment Framework
The assessment framework in P3M3 defines the structure for evaluating maturity. It ensures assessments are consistent, repeatable, and aligned with the model. Organizations use it for internal reviews or external benchmarking.
12. Perspective
A perspective in P3M3 represents a particular view of maturity, such as governance, risk, or organizational control. Perspectives help organizations break down maturity assessments into specific focus areas. This makes evaluation more targeted.
13. Attributes
Attributes are characteristics that indicate maturity within each perspective. They define what processes, behaviors, or evidence should be present at each level. They help organizations assess progress more precisely.
14. Self-Assessment
Self-assessment allows organizations to evaluate their maturity using P3M3 internally. It is cost-effective and provides insights into areas needing development. However, it may lack objectivity compared to independent assessments.
15. Independent Assessment
An independent assessment is conducted by external consultants trained in P3M3. This approach provides objectivity, benchmarking, and credibility. Many organizations choose this for a comprehensive evaluation.
16. Maturity Levels
Maturity levels in P3M3 are structured stages that represent organizational capability development. Each level builds on the one before it. They offer a pathway for organizations to progress toward optimized practices.
17. Model Scope
Model scope defines whether the assessment covers portfolio, programme, project, or all three domains. Organizations can choose based on their needs. This flexibility makes P3M3 adaptable to different contexts.
