Projects have been around for a very long time, and in that long time many techniques have been devised to help with the job of planning and controlling projects.
To make your use of PRIME® easier the techniques toolbox explains a number of key techniques and gives advice on how to use them. It is not constraining and exclusive though. Of course, not all techniques are needed in a single project.
The toolbox groups the different techniques into 5 areas.
Just drive with your mouse over one of the toolbox signs for more information.
