How to reduce equipment downtime without another war-room meeting

Separate unplanned vs planned downtime

Mixing planned and unplanned downtime lies to you.

• Unplanned downtime — the line stops because something failed or a fault forced a halt. This is what most “reduce downtime” programs target.
• Planned downtime — changeovers, sanitation, scheduled PM, known production pauses. Necessary, but managed differently.

If you dump both into one bucket, a good PM week can look like a reliability failure — or a chaotic breakdown week can hide inside “we were down for changeover.” Track them separately, then attack unplanned minutes on the assets that hurt throughput most.

To put a dollar frame on lost time, use the [downtime cost calculator](/guides/downtime-cost-calculator).

Capture stops so they leave history

You cannot kill what you cannot see twice.

Every meaningful unplanned stop should become a work order on the asset with:

• What happened (enough detail for the next person)
• When it started and when production resumed
• Who owned the restore
• Parts used and notes for next time

Chat threads die at shift change. Spreadsheets get rewritten. Asset-level history is how plants stop paying for the same diagnosis again. For field-level guidance, see [how to write a work order](/guides/how-to-write-a-work-order).

Practical rule for week one: pick one critical line or asset family. Force every stop into owned history. Do not boil the plant.

Kill repeat failures first

The fastest downtime reductions usually come from a short list of repeat offenders, not from twenty parallel initiatives.

1. Pull the last 2–4 weeks of asset history (or build that history now)
2. Rank by frequency × minutes lost (or dollar impact)
3. Pick the top three failure modes
4. Fix the root cause or wear item during a planned window
5. Add a short PM or kit so the same stop does not return
6. Re-check the ranking the next week

War-room meetings without this list produce action items that evaporate. Pareto on asset history produces work you can finish.

PM inside production windows

Preventive maintenance reduces downtime only when it is finished where the line can actually stop.

• Schedule PM into changeovers, sanitation, and planned pauses
• Convert due PM into owned work orders — not binder checkmarks
• Keep checklists short enough to fit the window
• Skip “calendar theater” that everyone knows will be deferred

Skipped PM does not protect the line. For plant PM practice, see [preventive maintenance for plants](/guides/preventive-maintenance-for-plants).

Parts and kits that shorten MTTR

Many “long repairs” are short wrench jobs with long waits.

• Link critical spares to the assets that consume them
• Kit parts for your top failure modes before the next stop
• Review stockouts that extended restore time last week
• Track parts on the work order so purchasing sees patterns

Faster restores show up in [MTTR](/guides/how-to-calculate-mttr). Parts readiness is often the cheapest lever.

Cadence: weekly downtime review

Treat downtime like production treats scrap — with a short, repeating review:

1. Unplanned minutes by asset / failure mode
2. Repeat stops since last week
3. Overdue PM on critical assets
4. Long restores (parts wait vs diagnosis)
5. One or two owned countermeasures for the next week — not ten

Same rhythm every week beats quarterly reliability theater. Keep the meeting short and evidence-based.

Where a CMMS fits in the loop

A CMMS does not magically reduce downtime. It makes the loop visible and owned:

• Capture stops as work on the asset
• Convert PM into jobs inside real windows
• Tie parts to the machines that need them
• Give managers a history-based weekly review instead of anecdotes

Corivo is built for that manufacturing loop: facility-based unlimited users so the full crew can participate, and guided setup so you can pilot the noisiest line without a multi-month project. Start where downtime hurts most, prove a week of durable history, then expand.
