When predictive maintenance practices indicate an upcoming problem, preventive maintenance can be:A. Put off until two or more additional factors consistent with an impending failure are seen
B. Budgeted for the next fiscal quarter as to not disrupt cash flow
C. Considered as one of many possible remediation measures
D. Scheduled to avoid system/component failure
The answer is D, “Scheduled to avoid system/component failure.” Predictive maintenance is aimed at preventing unplanned downtime. When the predictive maintenance process identifies a problem, maintenance on the item should be scheduled at the earliest possible time to prevent the small problem from becoming a much larger issue.
Predictive maintenance techniques are designed to help determine the condition of in-service equipment to estimate when maintenance should be performed.
