How do you reduce reactive maintenance?

A high reactive maintenance share is the single most expensive pattern in most plants. The good news is that it is structural, not personal: it responds to the same sequence of fixes almost everywhere. The aim is not to work harder, but to shift the balance of work from reactive to planned.

Step by step

1. Measure the reactive share honestlyPull reactive versus planned hours from the CMMS for a representative period. You cannot manage what you have not measured, and the true figure is usually higher than people expect.
2. Ring-fence protected time for planned workReserve a protected block of crew time for planned and preventive work, and defend it from everything except genuine emergencies. Without protected time, planned work is always the first casualty.
3. Eliminate the top repeat failuresRank repeat failures by cost, run root-cause analysis on the worst offenders, and verify the fix held. A short list of failures usually drives most of the reactive work.
4. Focus on critical assetsRank assets by failure consequence and concentrate preventive and predictive effort on the critical few rather than spreading it evenly.
5. Review on a short cadenceTrack the reactive percentage weekly, not monthly, so the trend is visible while you can still act on it.

Common pitfalls

• Trying to fix everything at once instead of attacking the top failures by cost.
• Letting emergencies erode the protected planned-work time until it disappears.
• Measuring work-order counts instead of hours, which understates the big jobs.
