If you’re performing a PM:
- Assemble everything needed to perform the PM, rather than making trips to and from the shop as needs arise.
- Look, smell, and listen for the unusual. This often leads to spotting problems the PM doesn’t identify.
- Note discrepancies in the procedure(s). Procedures often contain wasted steps and sometimes omit steps that should be included. Suggest revisions that improve the PM efficiency and/or effectiveness.
- Note defects in the process. For example, why must you remove a cover to make voltage measurements when measuring ports save time and reduce danger?
If you’re responding to a trouble call:
- Ask the operator(s) for a precise description of what is wrong (not what they think the cause is).
- Ask the operators to describe how the equipment should normally operate.
- Take as found data, including photographs.
- After assessing the problem, provide operations with a “best case” and “most likely” time estimate. Update this as you learn more.
