The average total MC/ ERV is about 4.5 %. Many corporations use
this number as part of their maintenance performance evaluation.
The question is if the number itself tells you anything about your
plants maintenance performance? The assumption would be that a lower
MC/ ERV number represents maintenance efficiency.
IDCON has seen low MC/ERV represent both efficient maintenance
organizations and poor maintenance performance. Our recommendations
if you use the number:
- Track the number over time, any manager can make short term
maintenance cost cuts. This doesn't mean long term performance
improves.
- Track the number together with other numbers. If you have a
higher MC/ERV, but a low production cost, you may just have different
accounting rules than your competitor, or you spend more on maintenance
to make gains in overall production reliability.
