How are FMEA results used in manufacturing decisions?

• A. Prioritize actions based on the most common defect.
• B. Allocate resources based on budget constraints.
• C. Prioritize risk mitigation actions by severity, occurrence, and detection to allocate resources effectively.
• D. Document supplier performance.

Answer: (C)

FMEA is a risk prioritization tool used to focus improvement efforts where they matter most. It looks at potential failure modes in a product or process and assesses three factors: how severe the impact would be if the failure occurs, how likely the failure is to happen, and how likely it is that current controls will detect it before it reaches the customer. By combining these factors, teams create a risk ranking that highlights which failures pose the greatest risk. This ranking guides where to allocate resources—into actions that reduce the likelihood of the failure, lessen its impact, or improve detection—so improvements yield the biggest reduction in overall risk. It’s not just about how often something defects; it’s about the overall risk picture and prioritizing mitigation accordingly. Other options miss this risk-focused approach: fixing the most frequent defects ignores severity and detection; budgeting constraints ignore risk priorities; and documenting supplier performance isn’t the primary use of FMEA outcomes.
