There are many myths about reliability, the most common one being that if we do excellent maintenance, we will have excellent reliability. We often make assumptions, for example, if I complete the following tasks (and you should):

• A CMMS, work management, planning and scheduling, linked to stores
• Maintenance plans for each equipment
• Specific PMs based on failure modes and consequences (each eqpt)
• Condition monitoring program – all PdM, Operator Inspections
• Precision work tools and practices
• Comprehensive RCA process
• Use of RCM in developing and updating maintenance plans.

Then operational reliability will improve, efficiency will improve, costs will come down, and profit willimprove. This discussion will provide a cautionary tale, and suggest some additional work that must be done to assure a reliable operation.
