Project -and Purpose-triangles

Project triangle we know but what is a Purpose triangle?

Purpose triangle we find at the project owner's playfield. It is here we put the responsibility for the purpose and the measurable expression of the same - namely the success criteria(s).

The success criteria is an ambition of the purpose, and if they meet the SMART requirements, then they have a time limit attached. The means to achieve the purpose and thus success criteria´s are the deliverables. Together, these three factors makes the purpose triangle.

As with the project triangle any modification of one tip needs an adjust at least one other tip to maintain balance. If in the example a greater reduction than 15% is required at the sammme date, you probably need to enhance the deliverables (possibly the amount of change management). Should the succes criteria be achieved faster it is probably only a more intensive change management process that can do the job.

Purpose triangles in other words is a tool for the change manager as project triangles is for the project manager.
