PM², PRINCE2, IPMA, and PMBOK are often mentioned in the same context, even though they aren't really comparable — they answer different questions. This article walks through what each one actually means, and when PM² is the most natural choice.
Four approaches
PM² is an open, free project management methodology developed by the European Commission and maintained by the PM² Alliance. It's a complete set that includes a governance model, a lifecycle, processes, and artefacts, tied together by a set of mindsets — designed from the outset to match the governance logic in EU projects.
PRINCE2 is a process-based, phased methodology maintained by PeopleCert (formerly Axelos), particularly popular in the UK and elsewhere in Europe. Its 7th edition, released in September 2023, brought a stronger focus on people leadership and sustainability.
IPMA isn't really a methodology at all — it's a competence baseline maintained by the International Project Management Association that assesses and certifies individuals across four levels (A–D). In Finland, certifications are administered by Projektiammattilaiset ry, with levels C and D being the most popular certificates.
PMBOK is a globally used body of knowledge maintained by PMI, and it's also the foundation for the PMP certification. Its 8th edition, released in November 2025, brought back some of the practical process guidance that the principle-based 7th edition had moved away from, and an updated PMP exam based on it was launched in July 2026.
Comparing the key differences
| Feature | PM² | PRINCE2 | IPMA | PMBOK / PMP |
|---|---|---|---|---|
| Nature | Lightweight, seamlessly integrated methodology set | Methodology consisting of principles, practices and processes | Individual competence baseline | Principle-based body of knowledge |
| Maintained by | European Commission / PM² Alliance | PeopleCert | International Project Management Association | Project Management Institute (PMI) |
| Cost to the user | Methodology is free; certification is optional and inexpensive | Foundation + Practitioner training and exams, typically a significant expense | Level-dependent assessment fee; C/D levels most popular in Finland | PMI membership and PMP exam fee |
| Designed specifically for | EU and public-sector projects | General use; widely adopted in the UK and Europe | Demonstrating individual competence, not for specific project environment | Global, industry-agnostic use |
| Latest edition | Continuously updated open guide | 7th edition (September 2023) | ICB4 competence baseline (ICB 5.0 to be published) | 8th edition (November 2025) |
When PM² is the natural choice?
PM² stands out in particular when a project is funded by the EU or delivered for a public-sector organisation. Its governance model and terminology are built to match exactly how EU institutions and programmes operate — which makes reporting and audits smoother, because both sides speak the same language from the start. PM² is also lightweight to adopt: it doesn't require a heavy certification process for the project team before application.
PM² isn't replacing PRINCE2, IPMA, or PMBOK — it solves a different problem: how to fit a project into the EU's own governance logic.
Can the methodologies be combined in practice?
Yes — and often that's exactly the right approach. PM² doesn't conflict with PRINCE2, IPMA, or PMP certification, because they operate at different levels: PM² defines the project's governance model and structure, while IPMA or PMP demonstrate individual competencies. In practice, many project managers running EU-funded projects can be IPMA- or PMP-certified and still use PM² as the project's actual steering model — the two don't exclude each other.
Summary
PM², PRINCE2, IPMA, and PMBOK aren't competing directly — they have their own strengths: PM² addresses a project's governance model and structure, PRINCE2 offers general-purpose steering model, IPMA demonstrates individual competence, and PMBOK provides a global, industry-agnostic framework. In an EU-funded project, though, PM² is the only one designed from the outset for that environment — which is why it deserves a place in a Finnish project professional's toolkit.
