Abstract

Carl and Fred discussing a listener question on maintenance strategies, and a company mandate metric comparing preventive and corrective maintenance tasks.

Key Points

Join Carl and Fred as they discuss how metrics can become a numbers game if they are used incorrectly.

Topics include:

• Sometimes a metric can alter behavior in the wrong way if people learn to “game” the system.
• How metrics can become a numbers game, especially if too much force is used to meet a threshold.
• Using RPN thresholds, as an example
• Ratio of corrective to preventive tasks is vulnerable to numbers game.
• Ask: what you are really looking for? How do we achieve that?
• The *quality* of corrective and preventive tasks is essential.
• RCM can be used to get the right tasks; needs the right inputs and criticalities.
• How do you encourage more preventive maintenance in a meaningful way.
• What are quality objectives for an RCM project? How can these be used?
• What are quality objectives in an FMEA project and how are they used?
• Trusting the team vs monitoring data
• What is role of Root Cause Analysis in this discussion?
• What can you do to improve maintenance procedures when in middle of production?
• Effectiveness of corrective actions
• How to implement future preventative actions
• Use of 80/20 rule in prioritizing tasks
