The principles

Proper implementation of the 7 principles is a key way of determining whether a project is applying the PRINCE2 method. The principles are:

Continued Business Justification:
Justification continues to apply as long as the project is still desirable, achievable and worthwhile. The moment these conditions no longer apply, the project should be discontinued.

Learn from Experience:
Lessons learned over the entire duration of a project are recorded, put into practice and made available to future projects for further use.

Defined Roles and Responsibilities:
A clear organisational structure with defined roles and responsibilities takes into account the different interests of the business, users and suppliers.

Manage by Stages:
PRINCE2 projects are divided into stages to allow for checks and balances. A stage authorisation is carried out to release resources for the next stage in each case.

Manage by Exception:
The limits of authority of each management level in the project management team are set by tolerances. The next highest level of management only needs to get involved if these tolerances are at risk of being exceeded.

Focus on Products:
A PRINCE2 project focuses on the products it is designed to deliver and the level of quality these products are required to meet. The project control system provides tools to ensure these quality requirements are fulfilled.

Tailor to suit the project environment:
This means adapting the themes, processes and management products to the project's context, complexity, scope and potential risks.
