I am trying to create a formula for On Time Delivery % which would be Percentage of projects delivered on-time compared to total projects delivered in the quarter
We define On Time as difference between Actual launch date and planned launch date being with +/- 5 days
How would I create this formula for the %? I can create the formula for difference in days using DDIFF.
How do I find the # of projects that fit the criteria and then calculate that as a % of the total projects?
