Your question is Root Cause Analysis for Discrepancies. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What is your approach to conducting a root cause analysis when a process discrepancy occurs?
Describe how you would contain the immediate impact, gather and validate evidence, involve relevant stakeholders, distinguish symptoms from the underlying cause, and define corrective and preventive actions. Explain how you would document findings, track implementation, and confirm that the discrepancy does not recur.
