According to lean Production Simplified, what should we do instead of blaming people for failures?

• A. Develop a fishbone diagram to find the root cause
• B. Retrain the person we are blaming
• C. Ask why 5 times to get to the root cause and then develop a plan to grow our people
• D. None of the above

Answer: (C)

In lean thinking, failures are signals to improve the process, not reasons to blame people. The practice of asking why five times is a simple, practical way to drill down to the true root cause, rather than stopping at a surface issue or attributing it to an individual. Once the underlying cause is found, the next step is to fix the system and support the people involved, turning the experience into a chance to grow their capability. This pairing of root-cause investigation with a plan to develop the team embodies the lean emphasis on continuous improvement and learning. While tools like a fishbone diagram can help map potential causes, they don’t, by themselves, ensure we address root causes and build people up. Blaming someone or simply retraining the blamed person misses the Lean path of systemic improvement and growth.
