Getting Good Eqipment History Feedback from Tradesmen
In order to facilitate your equipment reliability program, have your Planners include in the job steps to record “as-found” conditions upon disassembly of equipment.
Also, the Planner should take note of any ‘environmental’ conditions that may be a contributor to equipment degradation.
The Planner should consider including in the work order a component specific checklist of potential failure mode contributors. However, it should be stressed to Technicians to look with a critical eye and include all information.
When it comes to work order feedback; there is no such thing as too much.

One of the most effective tools for improving equipment reliability is equipment repair history analysis. Without meaningful work order completion comments and failure codes it is difficult to analyze equipment failure trends or common component failures. Make sure you have a work order for all maintenance and thoroughly document actual repair information.

• Collect meaningful equipment history files in order to establish time-failure profiles and as-found equipment conditions. Then adjust the intervals assigned to PM tasks, and initiate root-cause failure studies as may seem appropriate
• Perform automated trend analyses from Condition-Directed PM tasks, including automatic preset alarms to warn of an impending approach of critical equipment failure modes. Determine PF intervals from the warning time given.
• Track the actual trends of maintenance costs and system availability factors in order to measure the overall impact of the maintenance optimization programs – and adjust as required
• Use these measurements to continually adjust and improve the maintenance program.
