Fault Tree Analysis (FTA) - Mr. Simplifiers Tutorials

Introduction

• Focus: Fault Tree Analysis (FTA)
• Comparison: Similar to Fishbone Analysis
• Purpose: Conducting Root Cause Analysis (RCA)

Root Cause Analysis (RCA)

• Diagnoses a problem to identify root causes
• Corrective actions prevent reoccurrence

Fault Tree Analysis (FTA)

• Diagrammatic representation of failure path
• Top-down approach
• Identifies single or multiple root causes

Components of FTA

• Events: Specific occurrences or actions
• Logic Gates: Define relationships between events
  • AND Gate: Both inputs need to be positive for the output
  • OR Gate: Any one positive input can produce an output

Simple FTA Example

• Top-level event: Problem at hand
• Intermediate events: Breaking down into components
• Basic event: Root cause
• Undeveloped event: Needs further examination

Detailed FTA Example

• Problem: Car not starting in winter
• Categories: Fuel issues, Electrical issues

Fuel Issues

• No gas in tank
• No spare can of gas
• AND Gate: Combination of both leads to fuel problem

Electrical Issues

• Dead battery
• Alternator issues (undeveloped event)
• Starter issues (undeveloped event)
• OR Gate: Any one issue can lead to car not starting

Analysis Types

• Qualitative Analysis: Identifying events logically
• Quantitative Analysis: Probabilities of events and dependencies (not covered)

Applications of FTA

• Business processes
• Complex projects
• Everyday life problems (e.g., car starter problem)

Conclusion

• FTA is a useful tool for RCA
• Encourage further research on quantitative analysis
• Recommended to use FTA in both business and everyday life
