Preventive Maintenance scheduling is one of the most important—and most misunderstood—parts of a CMMS.

Most organizations create PMs.  
Far fewer optimize them.

In complex operations, PM scheduling directly impacts:

- Asset reliability

- Technician workload

- Downtime exposure

- Compliance readiness

- Maintenance cost

- Safety risk

The challenge is not simply creating PMs.  
The challenge is creating PM logic that reflects how equipment actually operates.

## How FaciliWorks 8i Supports PM Scheduling

FaciliWorks 8i supports multiple PM scheduling approaches, allowing organizations to match maintenance strategy to asset behavior and operational risk.

Common scheduling methods include:

- Calendar-based PMs

- Meter-based PMs

- Usage-based scheduling

- Inspection-driven PMs

- Trigger/event-based maintenance

This flexibility matters because not all assets fail the same way.

A rooftop HVAC unit, production conveyor, compressed air system, and emergency generator should not all follow identical PM logic.

# Calendar-Based PMs

The most common approach:

- Daily

- Weekly

- Monthly

- Quarterly

- Annual schedules

Best for:

- Regulatory inspections

- Routine safety checks

- Fixed compliance requirements

Challenge:  
Calendar-only PMs can create:

- Over-maintenance

- Unnecessary labor

- PM overload

- “Check-the-box” maintenance

Discussion point:  
Are your PM frequencies based on actual failure history—or legacy schedules nobody revisits?

* * *

# Meter-Based PMs

8i allows PMs to trigger from operational usage rather than fixed dates.

Examples:

- Runtime hours

- Mileage

- Production cycles

- Compressor hours

- Pump cycles

Benefits:

- Maintenance aligns to actual equipment usage

- Reduces unnecessary PMs

- Improves reliability planning

- Better for variable-use assets

This is especially valuable in facilities where equipment utilization changes seasonally or operationally.

# Inspection-Driven Maintenance

One of the most practical approaches in modern maintenance programs:

Instead of automatically replacing components:

- Inspect condition

- Perform work if needed

- Document findings

- Escalate only when thresholds are exceeded

Examples:

- Belt wear

- Vibration indicators

- Oil condition

- Leak detection

- Thermal inspection findings

This shifts maintenance from:  
Time-based → condition-informed.

# PM Scheduling Impacts More Than Maintenance

Poor PM logic affects:

- Safety

- Labor efficiency

- Inventory planning

- Production uptime

- Audit performance

Overdue PMs are not just maintenance metrics.  
They are operational risk indicators.

Questions worth asking:

- Which PMs generate the most corrective work?

- Which PMs never find issues?

- Which assets repeatedly fail despite PM compliance?

- Are PM intervals reviewed after failures?

* * *

# The Bigger Issue: PM Optimization

Many organizations treat PM setup as a one-time implementation task.

In reality, PM schedules should evolve continuously using:

- Failure history

- MTBF trends

- Downtime analysis

- Technician feedback

- Inspection findings

- Seasonal operating conditions

A mature maintenance program does not just complete PMs.  
It improves PM logic over time.

# Open Questions

- Are your PM schedules based on manufacturer recommendations or operational history?

- Which PM interval created the biggest reliability improvement?

- What percentage of your PMs are calendar-based vs meter-based?

- Which PMs feel preventive—and which feel administrative?

- How often does your organization review PM effectiveness?
