PRINCE2 is founded on seven key principles unique to the PRINCE2 method. These are:
- Continued business justification
- Learn from experience
- Defined roles and responsibilities
- Manage by stages
- Manage by exception
- Focus on products
- Tailor to suit the project environment

The 7 principles of PRINCE2 are just a small part of the PRICE2 method. To fully understand PRINCE2 you must come on an accredited PRINCE2 training course. Our PRINCE2 Foundation and PRINCE2 Practitioner courses have high pass rates because we believe in quality over quantity. We only use the best trainers and keep class sizes to a minimum so that all our delegates get the most from their training.
The 7 principles of PRINCE2 and what they entail:
1. Continued Business Justification
All projects should be justified by their Business Case. This ensures that all projects meet the goals of the business. A project should not be started without a sound Business Case in place. The project should be checked at regular intervals to ensure it is still valid. The Business Case is the basis for all decision-making. This principle ensures that the project is aligned to business objectives and the expected benefits. Justification for the project may change throughout but must always remain valid.
2. Learn from Experience
Everyone has to start somewhere but successful projects should be led by experienced project managers and teams who can draw from previous experience. Lessons can also be learnt at the start of the project and applied throughout.
3. Defined Roles and Responsibilities
Managing staff can be one of the hardest tasks for the project manager but without defined roles and responsibilities, the project can become muddled. Project teams can consist of permanent and temporary staff from different departments and even different organisations.
A strict project team structure is needed so that everybody knows their own and others’ responsibilities. Good communication is needed for this but is also improved if everyone knows what they’re doing.
Roles should be designated to represent the interests of the business, the user and the supplier. The roles can be split and combined so that they overlap and all parties are represented.
4. Manage by Stages
If a project is managed by stages then there are regular key points in which the Project Board meets to review progress and decide whether to go ahead with the project. Projects often run longer or involve more detail than predicted at the outset so meetings are needed to ensure the Board is still happy with the way the project is going.
PRINCE2 has a Project Plan that reveals an overview of the entire project but the project managers only plans the next stage each step at a time and the project board only accepts each stage as it comes.
There is a new plan for each stage and the overall Project Plan is updated as the project progresses.
Managing by stages allows senior management to keep track of the project and ensure every detail is approved.
5. Manage by Exception
PRINCE2 recognises six tolerance limits. these limits are implemented so that management can continue its work without unnecessary meetings or problems. the tolerance limits are defined so that as long as the project remains within defined parameters then no action is needed. The six tolerance limits are:
- Time
- Cost
- Quality
- Scope
- Risk
- Benefit
There are four levels of authority set, each time a tolerance is exceeded the next level of authority is consulted.
6. Focus of Products
PRINCE2 projects focus on the definition and delivery of products. Planning, controls and quality needs are all product based.
7. Tailor to Suit the Project Environment
PRINCE2 is tailored to suit the project’s environment. Size, risk, complexity, importance and people are all considerations when tailoring the project. Tailoring occurs before the outset of the project and allows the management to split or combine roles, combine processes and documents and decide which reports and decisions can be made virtually instead of in meetings.
Global communication has advanced to a stage that allows project teams to work across the world through virtual channels.
