CRL CRL - Certified Reliability Leader Risk Management and Criticality Analysis Questions and Answers 1 — Questions and Answers
Question 1: What is the primary purpose of a criticality analysis in reliability management?
- To prioritize assets based on their impact on safety, production, and cost (Correct answer)
- To calculate the MTBF of all equipment
- To identify spare parts requirements
- To schedule preventive maintenance tasks
Correct answer: To prioritize assets based on their impact on safety, production, and cost
Criticality analysis ranks assets by their potential impact so that maintenance and reliability resources are focused where failures matter most.
Question 2: In a risk matrix, risk is typically calculated as:
- Probability × Consequence (Correct answer)
- Frequency × MTBF
- Severity ÷ Likelihood
- Cost × Downtime
Correct answer: Probability × Consequence
Risk = Probability (likelihood of failure) × Consequence (severity of impact), which allows risks to be ranked and prioritized.
Question 3: What does FMEA stand for?
- Failure Modes and Effects Analysis (Correct answer)
- Facility Maintenance Equipment Assessment
- Functional Measurement and Evaluation Analysis
- Failure Management and Error Assessment
Correct answer: Failure Modes and Effects Analysis
FMEA (Failure Modes and Effects Analysis) is a structured method for identifying potential failure modes and their effects on system performance.
Question 4: In an FMEA, the Risk Priority Number (RPN) is calculated as:
- Severity × Occurrence × Detectability (Correct answer)
- Probability × Consequence × Cost
- Frequency × Duration × Impact
- MTBF × MTTR × Safety Factor
Correct answer: Severity × Occurrence × Detectability
RPN = Severity × Occurrence × Detectability, providing a numerical score to prioritize failure modes for corrective action.
Question 5: Which asset criticality tier should receive the most rigorous maintenance strategy?
- Critical (Tier 1) assets with high safety and production impact (Correct answer)
- General (Tier 3) assets with low replacement cost
- Non-critical (Tier 4) run-to-failure candidates
- Redundant (Tier 2) assets with backup systems
Correct answer: Critical (Tier 1) assets with high safety and production impact
Tier 1 critical assets that most affect safety and production warrant the most rigorous and proactive maintenance strategies.
Question 6: What is the purpose of a Failure Mode, Effects, and Criticality Analysis (FMECA)?
- To extend FMEA by quantifying the criticality of each failure mode (Correct answer)
- To replace root cause analysis after a failure
- To calculate OEE for critical assets
- To schedule corrective maintenance work orders
Correct answer: To extend FMEA by quantifying the criticality of each failure mode
FMECA adds a criticality ranking step to FMEA, allowing teams to numerically prioritize failure modes based on severity and occurrence probability.
