Adherence to plan (AtP): what it is and how to calculate it

Adherence to plan (AtP) shows how reliably a team delivers what it planned. In the Project Health Check it is defined as:

AtP = tasks due in the last 30 days that were completed on or before their due date ÷ all tasks due in the last 30 days

Example

Ten tasks were due in the last 30 days. Seven were completed on time, two late, one is still open. AtP = 7 ÷ 10 = 70%.

Good to know

• Tasks without a due date are not counted. The tool shows how many there are.
• If the export has no completed dates, AtP counts completed tasks only (“status only”) and says so.
• AtP is most useful as a trend. Compare it month by month with exports from different dates.

How to improve AtP

• Re-plan overdue tasks openly instead of leaving old due dates in place.
• Break large tasks into smaller ones with their own due dates.
• Make sure every task due soon has an owner.
