In all projects the manager has three elements he/she needs to control. The elements are the scope of the project, the costs and the time within which delivery needs to take place. These are referred to as the “iron triangle” and the good project manager constantly try to use the leverage available in these elements to ensure that the project moves forward to completion. Examples of how this leverage is used includes the following:
- If time is limited, the project manager would try to use more resources, or negotiate a change in scope to finish in time
- Where finance is limited (cost) the project manager will have to take a view and decide whether the scope should not be changed
An over determined project is one where all these aspects are fixed (cost, scope, time). Such projects are impossible to manage and often destined to fail.
