Key takeaway
Define recurrence once per service and per facility; let the system generate work orders so nothing depends on memory.
Where portfolios drift
Two buildings on the same contract quietly diverge when their schedules live in different heads. One supervisor remembers the quarterly deep clean; another does not. Six months later the client sees two different standards and assumes the whole program is inconsistent.
Rules beat reminders
Encode cadence as data: daily, weekly, specific weekdays, biweekly, monthly, quarterly or custom. Work orders generate automatically with the correct checklist attached, and coverage gaps become visible on a calendar rather than discovered after a complaint.
Measure the cadence, not just the completion
On-time completion percentage per facility exposes drift early. A site trending from 98% to 84% is telling you about staffing, access issues or scope creep months before it becomes a contract discussion.
