Root Cause Analysis Professional (5-Why, Fishbone, FTA)

A practical, workshop-driven curriculum covering three core RCA techniques and when to use them:

1. RCA Foundations

• Problem vs. symptom vs. root cause
  
  
• Evidence standards and cause validation
  
  
• Choosing the right RCA method for the problem
  
  

2. 5-Why Analysis

• Asking effective “why” questions
  
  
• Avoiding blame and linear traps
  
  
• Validating causes with facts and data
  
  
• Converting causes into robust actions
  
  

3. Fishbone (Ishikawa) Analysis

• Structuring causes by categories (6M/8P)
  
  
• Facilitating cross-functional brainstorming
  
  
• Narrowing to validated root causes
  
  
• Linking Fishbone outputs to actions
  
  

4. Fault Tree Analysis (FTA)

• Top events, logic gates, and pathways
  
  
• Deductive analysis for complex/system failures
  
  
• Quantitative vs. qualitative FTA (overview)
  
  
• When FTA outperforms simpler tools
  
  

5. Cause Validation & Evidence

• Cause-effect verification techniques
  
  
• Data checks, observation, and testing
  
  
• Avoiding common RCA pitfalls
