Without a project management method, those who commission a project, those who manage it and those who work on it will have different ideas about how things should be organised and when the different aspects of the project will be completed. Those involved will not be clear about how much responsibility, authority and accountability they have and, as a result, there will often be confusion surrounding the project. Without a project management method, projects are rarely completed on time and within acceptable cost - this is especially true of large projects.

A good project management method will guide the project through a controlled, well-managed, visible set of activities to achieve the desired results.

TPT adopts the principles of good project management to avoid the problems identified above and so helps to achieve successful projects. These principles are:

• a project is a finite process with a definite start and end
• projects always need to be managed in order to be successful
• all parties must be clear about why the project is needed
• what it is intended to achieve
• how the outcome is to be achieved, and what their responsibilities are in that achievement.
