An Alternative to Root Cause Analysis
Maintenance consultants often recommend performing a root cause analysis when a failure occurs. In the real world, however, repair techs are under pressure to get failed equipment up and running quickly, and go on to the next repair. Even if they have the expertise, they simply do not have the time.
There is another way.
Most failure modes have only a few possible systemic causes. If the tech checks a box from a symptoms list on the repair form, the system can generate a work order to address those causes.
For example, during a repair, the tech checks a box for “corrosion.” This potential failure mode could have systemic causes such as:
- Condensation in the raceway. Check similar enclosures for the same issue. Action: Install condensation drains on the affected raceways.
- Pest intrusion. Check this and similar enclosures for droppings, nest material, and (faint) footprints. Action: Implement site-wide pest control measures.
- Inadequate bonding. Check every metallic object for a bond that complies with Article 250, Part V.
