Planned Maintenance

All work is planned! If it is not pre-planned, then it is planned during execution. Pre-planning insures needed parts, materials and skills are available. Multiple trips to the tool room or store room are eliminated. Crafts are coordinated, avoiding wasted manpower caused by people standing around waiting. Work planned during execution suffers from false starts, missing parts or information and results in wasted manpower. Work that is not pre-planned can cost you as much as 25 times more to accomplish.

A good planned maintenance system is designed with an optimal mix of preventive (PM) and predictive (PdM) maintenance tasks. As much corrective maintenance as possible is planned to make best use of manpower and spares. The number of unplanned repairs is minimized. A good planned maintenance system will reduce the number of emergency repairs to a minimum because many of the failures that would be emergencies are found early while doing PM or PdM tasks. Because they are found before the failure occurs, they can be repaired with the least impact on production.
