Schedule adherence vs completion rate
One metric shows whether work happened when planned; the other shows whether the assigned outcome was completed.
Published · Updated · 4 min read · By Servenzo Operations Team.
The short answer
Schedule adherence measures whether work started or occurred within its agreed window. Completion rate measures how much assigned work reached the defined completed outcome. A job can be on time but incomplete, or completed after a late arrival, so teams should review both with reason codes.
Schedule adherence and completion rate compared
| Criterion | Schedule adherence | Completion rate |
|---|---|---|
| Question | Did work occur within the planned window? | Did assigned work reach the completion condition? |
| Numerator | Jobs or shifts within window | Jobs or tasks completed |
| Common cause | Travel, overrun, absence or access | Scope, parts, skill, access or follow-up |
| Risk | Hides quality if used alone | Hides lateness if used alone |
Bottom line: Use both, with published definitions and reasons for customer-caused, provider-caused and approved exceptions.
Choose the denominator deliberately
Exclude cancelled or invalid work only under defined rules. Quietly removing difficult jobs makes performance appear better while hiding the operating problem.
The reason code leads to action
A percentage shows scale; the reason distribution shows whether to change capacity, travel, access, parts, scope or customer communication.
A practical process
- Define the service window and the completion condition.
- Define included, excluded and rescheduled jobs.
- Calculate both rates with volume and reason codes.
- Review the largest controllable cause and assign an action.

Questions about schedule adherence vs completion rate
What counts as on time?
Use the customer or contract window, not a hidden internal target. Define whether arrival, start or completion is being measured.
Should partial work count as completed?
Only if the defined assigned outcome allows partial completion. Otherwise use a separate partial status and retain the follow-up.
Can both metrics be 100%?
Yes for a period where every included job occurred within the window and reached the defined completion outcome, but show job volume and exclusions.
