7 Common Mistakes When Planning Preventive Maintenance

Short Answer

A preventive maintenance proposal should define covered assets, task lists, frequencies, competence, evidence, exclusions, escalation and measurable outcomes. Compare the operating system, not the number of visits.

Mistake 1: Buying a vague promise

List each covered machine, configuration and critical subsystem. Separate operator checks, planned service, condition-based work, corrective repairs and parts so quotations cover the same responsibility.

Mistake 2: No evidence standard

Require task sheets derived from the manufacturer manual, named technicians, instruments where needed, readings or photographs, findings, work-order escalation and a traceable service record.

Mistake 3: Activity without acceptance

Acceptance should confirm work completed, unsafe or out-of-limit findings isolated, recommendations prioritized, production handover recorded and the next due work agreed.

Mistake 4: Comparing only the headline fee

Compare planned labor and travel, shutdown time, consumables, condition-monitoring work, parts, emergency response and exclusions. A low visit fee can hide a narrow scope or costly corrective work.

Mistake 5: Ignoring technical and access risk

Do not let a contractor change intervals, lubricants, settings or safety procedures without the machine manual and technical approval. Preserve the machine history and approve access to controls.

Mistake 6: No named owner

Assign one accountable owner, one escalation route and dated actions. Shared responsibility without ownership allows gaps to remain open.

Mistake 7: No outcome review

Review results against the approved objective and baseline. Completion of visits, tickets, training hours or calculations is not proof of operational improvement.

Frequently Asked Questions

What should be fixed before proposals are compared?

The required scope, evidence, acceptance result, exclusions, owner and review date.

Is the lowest price automatically the best option?

No. Compare total cost, operational risk and the ability to prove the required outcome.

What is the next practical step?

Share the machine list, operating hours and failure history for a scoped preventive maintenance review.
