Conditioned Based Monitoring
A benchmark study by the Aberdeen Group supports the findings of prior benchmarking indicating: “Best-In-Class Performers will have 45-55% of their total labor hours driven by Condition Based Monitoring (CBM) inspections and the elimination of defects identified through CBM activities”. Without a thorough understanding of the defects present in a facility, it is virtually impossible to effectively plan and a schedule work making a robust CBM process critical for enabling the Proactive Workflow Model. Returns on asset reliability come from 4 primary sources:
Allied Reliability has studied the practices of over 1,000 diverse worldwide locations confirming prior findings that increased CBM is linked to lower maintenance costs, while more time-based PM activity is linked to higher costs. When considering Return On Asset Reliability (ROARTM), maintenance cost savings only account for 15-30% of the total opportunity for savings. To achieve Best-In-Class results, “Failure Modes Driven” maintenance strategy is paramount because the overwhelming majority of failure modes are not linked to time. A sound “Failure Modes Driven” Maintenance Strategy will build only PM inspection tasks when a suitable CBM task is either technically unfeasible or economically impractical. The mapping of failure modes to the appropriate inspection becomes the foundation for Asset Health Management. A true understanding of the health of a facility’s mechanical, electrical, and stationary assets is only possible when all of the likely failures are anticipated on a significant percentage of those assets.

According to an independent benchmark study performed by the Aberdeen Group, Best-In Class Performers show 26% higher Return on Invested Capital, 15% higher Asset Utilization, and 40% Lower Maintenance Cost than that of Average Performers.
