In our last iLearnReliability Tip #2: Clean & Prioritize Your CMMS, we discussed that in order to effectively get your reliability program going, you first need to have a clear understanding of your physical assets and identify how critical each asset is to the plant's operation.

Now, with your most critical assets defined, it is time to study the CMMS to determine for each asset:

• Mean Time Between Failure (MTBF)
• Mean Time to Repair (MTTR)
• Cost of repair
• Bill of Material (BOM) accuracy
• Spare parts availability, and
• A reasonably accurate Failure Mode Effects Analysis (FMEA) based on the asset's history as documented by the CMMS or derived from tribal knowledge.

This assessment will provide a reasonable picture of the current reliability of your assets and provides you a good starting point from which to set goals and to identify important elements of your new program. This may seem to be a daunting task at first, so only include the MOST critical assets (such as the top 20%). You can decide where your cut-off is, though it is best to add less critical assets only after the most critical have been done.
