FMEA (Failure Mode and Effects Analysis)
Overview
FMEA is a systematic, proactive method for identifying and evaluating potential failure modes in a system, design, process, or service. It helps to assess the risk associated with each failure mode and prioritize actions to prevent or mitigate failures.
Key Components
- Failure Modes
- Effects
- Causes
- Controls
- Risk Priority Number (RPN)
Applications
- Design Analysis
- Process Improvement
- Risk Management
- Quality Control
- Preventive Maintenance
Benefits
- Proactive Problem Prevention
- Risk Reduction
- Improved Reliability
- Enhanced Safety
- Cost Savings

Risk Assessment Criteria
Severity
- Impact of failure
- Scale from 1 to 10
- Higher = more severe
- Criticality assessment
Occurrence
- Likelihood of failure
- Scale from 1 to 10
- Higher = more likely
- Frequency estimation
Detection
- Ability to detect failure
- Scale from 1 to 10
- Higher = less likely to detect
- Control effectiveness
