PRINCE2
PRINCE2 is a structured method for governing projects, built around one question the project must keep answering: is this still worth funding? PRINCE2 says almost nothing about how the work gets done and a great deal about who is allowed to decide it continues. This page explains all seven principles, all seven practices and all seven processes — one at a time, in plain language.

What PRINCE2 is for
PRINCE2 is often compared with Scrum, and the comparison confuses almost everyone the first time. That is because the two are not alternatives. They answer completely different questions.
Scrum describes how a team turns a list of work into working software. PRINCE2 describes how an organisation decides to start a project at all, keeps checking whether it should carry on, and stops it when the answer changes. One is about building. The other is about deciding and funding.
The name is an acronym: PRojects IN Controlled Environments. It came out of the UK government in 1989 and is now widely used across Europe, particularly in the public sector and in regulated industries where a supplier must demonstrate control to win a contract.
A terminology change worth knowing
Before we go through the elements, one practical warning. PRINCE2 was updated in 2023, and the seventh edition renamed one of its three groups. What used to be called the seven themes are now called the seven practices.
The substance is largely the same, but most training material, blog posts and job descriptions online still say "themes". If you meet that word, it refers to what this page calls practices. Knowing both terms saves confusion in an interview.
The seven principles
The principles are the non-negotiable part. A project can drop paperwork, simplify processes and skip roles, and still be PRINCE2 — but if it violates a principle, it is not PRINCE2 any more, whatever the documentation says. Here is each one, and what it actually asks of you.
1. Continued business justification
There must be a documented reason for the project, and it must still hold at every checkpoint. Not written once for budget approval — reviewed repeatedly. If the reason disappears, the project stops.
2. Learn from experience
Lessons are looked up at the start, recorded during, and passed on at the end. The method makes this an explicit duty because organisations reliably forget otherwise.
3. Defined roles and responsibilities
Everyone knows who decides what. Three interests must always be represented: the business paying, the users who will use it, and the suppliers building it.
4. Manage by stages
The project is split into stages, and the board authorises only one at a time. You plan the next stage in detail and the rest of the project roughly — a hedge against planning what you do not yet understand.
5. Manage by exception
The board agrees limits — for time, cost, scope, risk, quality and benefit — and then leaves the manager alone inside them. Escalation happens only when a forecast breaks a limit.
6. Focus on products
Agree what will be delivered and to what quality before discussing how long it takes. A project defined by activities has no way to check whether it is finished.
7. Tailor to suit the project
Scale the method to the size and risk of the work. Applying the full apparatus to a small project is the most common way PRINCE2 gets a bad name.
The seven practices (formerly themes)
If the principles are what you must believe, the practices are what you must keep an eye on throughout. Each one is an aspect of the project that has to be managed continuously rather than dealt with once. Here is each one and the question it keeps asking.
| Practice | What it covers | The question it keeps asking |
|---|---|---|
| 1. Business Case | The justification and expected benefits | Is this still worth doing? |
| 2. Organizing | Roles, decision rights, reporting lines | Who decides this, and who must know? |
| 3. Plans | What will be delivered, by when, by whom | How do we get there from here? |
| 4. Quality | Acceptance criteria and how they are checked | How will we know it is good enough? |
| 5. Risk | Uncertain events that might affect the outcome | What might happen, and what would we do? |
| 6. Issues | Things that have already happened, plus change requests | This happened — who decides what now? |
| 7. Progress | Tolerances, measurement and escalation | Are we still inside the agreed limits? |
Two of these are worth a closer look, because the distinction between them is where teams usually get muddled.
The seven processes
The processes are the timeline: what actually happens, in what order, and who is doing it. Read them in sequence and you have the whole life of a PRINCE2 project from the first idea to the final report.
| Process | When | What happens, and who does it |
|---|---|---|
| 1. Starting up a Project | Before approval | A short check that the idea is viable at all. Produces a brief, not a plan. |
| 2. Directing a Project | Throughout | What the board does: authorise, decide, escalate. Runs the whole time. |
| 3. Initiating a Project | After approval | Building the detailed foundation: business case, plans, quality and risk approach. |
| 4. Controlling a Stage | Inside each stage | The manager's daily work: assign, monitor, handle issues, report. |
| 5. Managing Product Delivery | Inside each stage | The team actually builds. This is where Scrum sprints would live. |
| 6. Managing a Stage Boundary | End of each stage | Report what was done, re-check the business case, plan the next stage. |
| 7. Closing a Project | At the end — or early | Hand over, confirm acceptance, record lessons. Used for cancellation too. |
Notice two things about this list. First, processes 4, 5 and 6 repeat for every stage — they are the loop the project runs in. Second, "Closing a Project" is used both when the project succeeds and when it is stopped early. PRINCE2 treats cancellation as a proper ending with a proper process, not as an embarrassing exit.
Who sits on the board
Principle 3 said three interests must always be represented. Here they are, and the reason the split matters is that these three interests genuinely conflict — the business wants it cheap, the users want it good, the suppliers want it feasible. Naming them separately stops one of them quietly winning by default.
Executive — the business
Owns the business case and the money, and has the final say. Always one person: PRINCE2 is explicit that a board cannot own a decision jointly.
Senior User
Represents the people who will use the result, and is accountable for the benefits actually being realised after delivery.
Senior Supplier
Represents those building it, and is accountable for the solution being technically viable and properly resourced.
PRINCE2 next to Scrum
PRINCE2 answers
- Should this project continue at all?
- Who is accountable for the benefits?
- What limits may the manager work within?
- When is stopping the right answer?
Scrum answers
- What do we build this sprint?
- How does the team inspect and adapt?
- What does done actually mean?
- How do we surface problems in days?
Read the two columns together and it becomes obvious that neither replaces the other. That is exactly why the combination is common, and why the official PRINCE2 Agile variant exists to formalise it.
How this shows up in real delivery
For an engineering team, PRINCE2 mostly shows up as stage boundaries: predictable moments when funding is re-examined and evidence is expected. Teams that fare well treat those as genuine reviews and bring outcome numbers to them. Teams that fare badly bring a percentage-complete figure, which answers a question nobody at the board actually asked.
Where it degrades
- A business case written once for approval and never reviewed — principle 1 simply absent while the paperwork claims otherwise.
- The full documentation set applied to a small project, where governance costs more than the risk it manages.
- No tolerances agreed, so management by exception quietly becomes management by interruption.
- A board that meets but has never actually stopped anything, which makes every stage gate ceremonial.
- Issues logged as risks, so a problem that has already happened waits for someone to reclassify it.
When to use it
Use it when
- Funding is released in stages and someone must justify each release.
- Public sector or regulated work where recognised governance is expected or contractually required.
- Several organisations are involved and decision rights must be written down.
- The organisation genuinely wants the ability to stop a project cleanly.
Avoid it when
- Continuous product development with no defined end — there are no stages to authorise.
- A small project where the documentation would outweigh the work itself.
- Expecting it to tell the team how to build — it deliberately does not, and never will.
- The board will never exercise its authority to stop, which turns the whole method into ceremony.
