Which maintenance KPI measures the average time between consecutive equipment failures?
Answer: Mean Time Between Failures (MTBF)
MTBF calculates the average operational time between failures, indicating equipment reliability.
A Failure Mode and Effects Analysis (FMEA) is used in maintenance planning to:
Answer: Identify potential failure modes and their impact before they occur
FMEA proactively identifies how components might fail and assesses the severity and likelihood of each failure mode to prioritize prevention efforts.
Deferred maintenance is BEST described as:
Answer: Necessary maintenance that has been postponed to a future date
Deferred maintenance refers to maintenance tasks that were due but delayed, often increasing the risk of equipment failure and higher future repair costs.
In a maintenance cost analysis, which category includes parts, labor, and contracted repair services?
Answer: Direct maintenance costs
Direct maintenance costs encompass all expenditures directly tied to maintaining equipment, including parts, technician labor, and outside repair services.
What is the purpose of a root cause analysis (RCA) following a major equipment failure?
Answer: Identify and eliminate the underlying cause to prevent recurrence
RCA investigates the fundamental reason a failure occurred so corrective actions can be implemented to prevent the same failure from happening again.
Vibration analysis is a condition-monitoring technique MOST useful for detecting early signs of:
Answer: Bearing wear, imbalance, or misalignment in rotating machinery
Vibration analysis detects subtle changes in rotating component behavior, allowing early identification of bearing defects, imbalance, and shaft misalignment.
When a CEM implements a parts standardization program across a mixed fleet, the PRIMARY benefit is:
Answer: Reduced parts inventory complexity and lower procurement costs
Parts standardization reduces the number of unique SKUs a fleet must stock, lowering inventory investment and simplifying procurement and technician training.
