7.1 The PRINCE2 principles
The principles on which PRINCE2 is based originate from lessons learned from projects both good and bad. They provide a framework of good practice for those people involved in a project. If a project does not adhere to these principles, it is not being managed using PRINCE2, because the principles are the basis of what defines a PRINCE2 project.
The seven PRINCE2 principles are listed in section 5.2.
It is the adoption of these principles that characterizes whether a project is using PRINCE2, not the adoption of processes and documents alone. The principles facilitate good use of PRINCE2 by ensuring that the method is not applied in an overly prescriptive way or in name only, but applied in a way that is sufficient to contribute to the success of the project.
