5 Whys
The 5 Whys is a simple but powerful problem-solving method where you ask "why" five times to find the root cause of a problem. It's like peeling back layers of an onion until you find the core issue. Created by Toyota, it's now used in many companies to improve processes and fix problems. Instead of just fixing surface-level issues, this method helps teams discover and address the deeper causes. It's similar to Root Cause Analysis or Ishikawa (Fishbone) Diagrams, but much simpler to use and understand.

Example Interview Questions
Senior Level Questions
Q: Can you describe a situation where the 5 Whys method didn't provide a clear solution and how you handled it?
Expected Answer: A strong answer should explain how they combined 5 Whys with other problem-solving tools, recognized when to broaden the investigation, and successfully resolved complex problems using multiple approaches.
Q: How would you implement a 5 Whys program across multiple departments?
Expected Answer: Should discuss training strategies, creating standard templates, facilitating cross-department collaboration, and measuring the program's success through specific metrics and results.
Mid Level Questions
Q: What's the difference between using 5 Whys and a Fishbone diagram?
Expected Answer: Should explain that 5 Whys is more straightforward and focuses on one cause-and-effect chain, while Fishbone diagrams explore multiple potential causes. Both tools can be complementary.
Q: How do you know when you've reached the true root cause using 5 Whys?
Expected Answer: Should explain that the root cause is reached when the answer points to a process or system that can be changed, and further 'whys' don't yield useful information.
Junior Level Questions
Q: Can you walk me through the basic steps of conducting a 5 Whys analysis?
Expected Answer: Should explain the process of starting with a problem statement, asking why it occurred, and continuing to ask why for each answer until reaching the root cause, usually around 5 levels deep.
Q: What are the benefits of using the 5 Whys method?
Expected Answer: Should mention its simplicity, effectiveness in finding root causes, ability to prevent problem recurrence, and how it helps avoid jumping to conclusions.
