PM Schedule & Workload Balancer
Prevent labor peaks and balance recurring inspection schedules across maintenance crews.
Q:
Why is workload leveling vital for 52-week preventive maintenance schedules?
Without leveling, calendar frequencies (monthly, quarterly, annual) synchronize into massive labor spikes, resulting in deferred PMs, technician burnout, and overtime costs. Workload leveling staggers inspection tasks evenly across the 52-week cycle.
