What would you do

A customer or third-party auditor is coming in three weeks. How do you get the plant ready?

About the work

What root cause tools do you use most, and give me an example where one of them changed what you thought the cause was.

What they are checking: Whether they use tools like five whys or fishbone thoughtfully rather than as a formality.

How do you know a measurement system is good enough to trust before using it to accept or reject product?

What they are checking: Whether they understand gauge capability and calibration, which underpin customer certifications and testing.
