Root cause analysis is a methodology that needs to know the first action that leads to a sequence which in turn leads to a problem and finds a way to solve the problem.So, unless the bones are mended, the pain will not be cured. □ Solution: In this example, the problem is a broken wrist, the symptom is pain in the wrist and the root cause is broken bones. □ Problem: A broken wrist hurts a lot but the painkillers will only take away the pain not cure the wrist you will need a different treatment to help the bones to heal properly. □ Solution: The solution will be using refrigerator to store this drug even while shipping it. □ Problem: A drug has been doing badly in the last few weeks, the root cause analysis revealed that the cause is related to non-optimum storage temperature which happened due to starting of the summer. Carry any identified actions over to the counter-measure activity of the RCA.List any additional actions that could be implemented to prevent this problem from occurring again and assign an owner and a due date for each recommended action.Document any controls in place designed to prevent or detect the problem.Next identify the Escape Point, which is the closest point in the process where the root cause could have been detected but was not.When reviewing a process FMEA, review the process flow or process diagram to help locate the root cause.List all probable causes and how many times they occur.Identify the impact of the failure by defining the severity of the problem or effect of failure.List the current problem as a failure mode of the design or process.If the problem is not included in the FMEA, the team should add any known information and then complete the following steps: The team should determine if the problem or effect of the failure was identified in the FMEA and if it was, how accurately the team evaluated the risk.In many companies, if a major problem is detected in the process or product, the team is required to review any existing FMEAs in relation to the problem. FMEA is a well-defined tool that can identify various modes of failure within a system or process. Failure Modes and Effects Analysis (FMEA) Of course, it may take asking why more than five times to solve the problem the point is to peel away surface-level issues to get to the root cause.ħ. Pareto charts are based on Pareto’s law, also called the 80/20 rule, which says that 20% of inputs drive 80% of results.
