How do you investigate and resolve a quality problem that keeps recurring in a production process?

The candidate is expected to describe how they gather data to identify the root cause, which corrective and preventive actions they propose, and how they confirm the problem does not happen again. A real example of a situation they resolved would strengthen their answer.

What experience do you have with the ISO 9001 standard, and how do you ensure compliance in day-to-day operations?
