What does a low OEE score primarily indicate about a manufacturing process?
Answer: Significant losses in availability, performance, or quality
A low OEE score signals that the process is experiencing significant losses in at least one of the three OEE components: availability, performance, or quality.
Which reliability metric measures the percentage of time equipment is operational when needed?
Answer: Availability
Availability measures the proportion of time a system is in a functioning condition and ready for use when required.
What is the failure rate (λ) if MTBF = 500 hours?
Answer: 0.002 failures/hour
Failure rate λ = 1 ÷ MTBF = 1 ÷ 500 = 0.002 failures per hour.
A world-class OEE benchmark in manufacturing is typically:
Answer: 85% or higher
World-class OEE is generally considered to be 85% or higher in manufacturing environments.
Which of the following is a leading indicator in reliability performance management?
Answer: Percentage of PM tasks completed on schedule
PM completion rate is a leading indicator because it measures proactive actions taken before failures occur, not results after the fact.
In reliability-centered maintenance, what does a 'bad actor' asset typically refer to?
Answer: Equipment with the highest frequency of failures or maintenance costs
A 'bad actor' is an asset that disproportionately contributes to downtime, failures, or maintenance costs and warrants prioritized attention.
