Understanding Asset Related Criticality: Managing asset by criticality (Part 3)

Darrin Wikoff shares the final installment in his three part series on Asset Criticality.


Once we understand the meaning behind the number, the criticality analysis model becomes a tool used to develop the asset management plans. For those assets that are within the top 20%, reliability specialists will typically proceed with a Failure Modes Effects Analysis (FMEA) to assess the risk priority associated with each type of failure, and to determine the appropriate corrective actions. But we again must consider the critical characteristics that are common throughout the organization, across all assets, critical or not. In doing so, asset management becomes a plant wide process. If “Mission Impact” is commonly critical, than Engineering may need to considered equipment redundancy plans. For those organizations that find “Spares Lead Time” particularly critical, a Materials Management improvement program should be initiated. Those organizations that struggle to manage the cost of “Corrective Maintenance History”, Maintenance should evaluate existing preventive maintenance effectiveness or examine the methods by which work is executed.
When managing asset-related risks, we only have a few fundamental decisions we can make, control it, eliminate it, or accept the risk. Understanding how non-conformances impact your organization’s ability to meet strategic objectives is the first step towards establishing an economical asset management system.
