π About Fault Tree Analysis
What is FTA?
Fault Tree Analysis is a top-down approach to analyze system failures. It helps you understand:
- How component failures lead to system failures
- Critical paths and single points of failure
- Probability of system failure
- Most effective prevention strategies
FTA vs FMEA
FMEA: Bottom-up analysis - "What can go wrong?"
FTA: Top-down analysis - "How can this specific failure occur?"
Best Practices
- Start with a specific, well-defined top event
- Include relevant stakeholders in the analysis
- Link to existing FMEA data for consistency
- Use both qualitative and quantitative analysis
