Route adherence — did the route get done?
The first KPI is the simplest and the most important: of the stops scheduled for this tech in the last 7 days, what percentage did they actually complete? Route adherence catches the slow drift that kills a service business — the one stop a day that gets pushed to Friday, the recurring visit that quietly becomes biweekly, the customer who calls because the gate was never opened.
Adherence shows as a percentage with the raw "completed / scheduled" count next to it, so a 92% week from a tech with 24 visits gets the credit it deserves over a 100% week from a tech with 6.
