Understanding Project Statuses
You can set up statuses for a project as development progresses from one phase to the next. For example, the project might move from a programming phase to a manager review phase. For each of these transitions you will define the these parameters:
Whether this project status rule is active
The System Role to which this project status transition applies
The related "To" project status
The related "From" and "To" SAR* statuses
Complete the From and To SAR status only if you have SAR integration turned on.
