Root Cause Analysis (RCA)



Root Cause Analysis (RCA) is a problem-solving technique that seeks to identify the primary cause of a problem. By focusing on the root cause, organizations can prevent the problem from recurring and develop long-term solutions that improve efficiency, reduce costs, and increase customer satisfaction.

RCA uses tools such as the 5 Whys and Cause & Effect Diagram to identify the underlying causes of a problem. The 5 Whys technique involves asking "why" multiple times to dig deeper into the root cause. The Cause & Effect Diagram categorizes potential causes, such as people, process, and equipment, to identify root causes quickly.

This RCA presentation is designed to provide participants with a comprehensive understanding of Root Cause Analysis (RCA) as a problem-solving technique. The presentation highlights the importance of identifying the root cause of a problem and how RCA can be used to achieve this. Participants will learn how to apply common RCA tools such as the 5 Whys and Cause & Effect Diagram to identify the root cause of a problem. They will also gain knowledge on how to prioritize root causes using a Pareto Chart to focus on the most significant causes first. The presentation will also cover the pitfalls in root cause analysis, highlighting the importance of avoiding making assumptions, involving stakeholders, and making RCA an ongoing process. By the end of the presentation, participants will have a deep understanding of RCA and be equipped with the skills needed to identify and solve problems effectively.
