Can you tell me about your process of identifying and correcting flaws in production?

"Initially I observe the current process and interview stakeholders to identify the problem using the 5 Whys. Then I identify the root cause using a Fishbone Diagram. Next, it's on to Corrective Action Plan time, where I perform 'Plan - Do - Check - Act - otherwise known as the PDCA Cycle. Follow up is oftentimes an issue so I follow up later at a predetermined time to verify and validate that the production flaws are corrected."
