Total Productive Maintenance (TPM)

Total Productive Maintenance shares basic equipment care between operators and the maintenance team so failures are prevented at source and equipment runs at its full design capability.

What world-class looks like

Operators own basic equipment care, planned maintenance runs on schedule, and hourly production vs target is tracked and improving continuously.

How mature is your operation?

These are the questions Compass asks for this practice, and the levels it scores you against.

Production tracking

Measuring parts produced vs target, good vs scrap, and cycle time vs target on each shift.

How do you track production output and cycle time against target on your critical equipment?

Level 1 → 5World class at level 4

  1. We don't track parts produced vs target during the shift
  2. We estimate total parts at the end of each shift
  3. Manual hour-by-hour tally on paper or spreadsheet — target, actual, good, scrap
  4. Tablet-based hour-by-hour tracking with target vs actual and cycle timeWorld class
  5. Automatic part counters feed a live production board against target

Autonomous maintenance

Operator-led basic equipment care: cleaning, inspection, minor adjustments.

How involved are your machine operators in basic equipment care?

Level 1 → 5World class at level 4

  1. Operators only run the machine — all maintenance is done by specialists
  2. Operators clean when they feel it is needed
  3. Operators follow a basic cleaning checklist
  4. Operators perform defined daily/weekly inspections and minor adjustmentsWorld class
  5. Operators detect and address abnormalities before they become failures

Failure analysis (RCA)

Structured root cause analysis after unplanned equipment failures.

When equipment fails unexpectedly, how do you investigate the root cause?

Level 1 → 5World class at level 4

  1. We fix it and move on — no formal investigation
  2. Informal discussion between technicians
  3. Written record of what failed and what was done
  4. Structured RCA (5-Why or fishbone) for significant failuresWorld class
  5. RCA is standard practice for all unplanned events; findings update PM schedules

Maintenance KPI tracking

Trending MTBF, MTTR, downtime hours, and shift throughput against target — and acting on the data.

Which maintenance performance metrics do you review regularly?

Level 1 → 5World class at level 4

  1. We don't track maintenance KPIs formally
  2. We track downtime hours informally
  3. We track MTBF, MTTR, or throughput vs target on a spreadsheet
  4. KPIs are reviewed in a regular maintenance meeting with trend dataWorld class
  5. Live KPI dashboard; targets set and reviewed monthly with improvement actions
