Preventive Maintenance

Prevent unplanned downtime by standardizing the planning and execution of recurring maintenance tasks. The Preventive Maintenance module in OpexMx delivers an end-to-end workflow—from policy design and work order scheduling to technician execution and digital records.

What it solves

  • Keeps critical assets within OEM tolerances and regulatory requirements.
  • Reduces firefighting by surfacing maintenance work before breakdowns occur.
  • Gives planners a single view of what is due, overdue, or completed across plants.

Core capabilities

  • Maintenance plan library with frequencies based on runtime, calendar, or custom triggers.
  • Automatic work order generation directly into the Ticketing System.
  • Technician-ready checklists, technical documents, and safety notes.
  • Completion tracking with electronic signatures, photos, and time spent.
  • Smart escalations when tasks slip or require follow-up work.

Implementation playbook

  1. Baseline your assets. Import critical machines, spare part hierarchies, and OEM manuals into OpexMx Master Data.
  2. Author the plan. Create task lists with step-by-step instructions, required tools, and quality checks.
  3. Set smart triggers. Use runtime counters, production batches, or simple calendar intervals to generate work orders.
  4. Assign ownership. Map tasks to trade skills, crews, or vendors so scheduling stays realistic.
  5. Monitor execution. Use the calendar and dashboard to watch upcoming workload, completion rates, and overdue tasks.

Data captured

  • Asset, task list, and BOM references.
  • Planned vs. actual labor hours and cost.
  • Findings, condition readings, and follow-up actions.
  • Attachments such as inspection photos or calibration certificates.

Best practices

  • Start with the top 20% of assets that drive 80% of downtime risk.
  • Keep checklists short and actionable; reference full SOPs via the Docs & Knowledge Center.
  • Combine with Predictive Maintenance alerts to adjust frequencies dynamically.
  • Review performance monthly to retire obsolete tasks or rebalance workload.

KPIs to watch

  • Preventive maintenance compliance (% tasks completed on time).
  • Ratio of preventive vs. corrective work orders.
  • Mean time between failures (MTBF) on covered assets.
  • Labor utilization by trade during planned maintenance windows.
