To carry out a 5 whys analysis, you need to gather a team of people who are affected by the problem.Īs the name suggests, in the 5 whys analysis the question ‘why?’ is asked five times in the course of finding the root cause of a problem. Following we have listed some that are widely used and more effective in problem-solving. Many root cause analysis tools are out there. Review and evaluate the impact of the corrective actions. Make sure that you clearly communicate them to the people who will be involved. Keep at it until finally you have discovered the fundamental cause for the problem at hand.ĭecide the corrective actions you need to take to eliminate the problem and prevent it from recurring. You can use a 5 whys diagram or a fishbone diagram here.ĭig deeper by continuing to ask why after the first layer of causal factors. Together with the team, brainstorm the possible factors for the problem by asking ‘why?’. Gather a team of people directly involved in the execution of the process and corrective actions, and experts whose input can help find solutions faster. Step 2: Determine the factors that caused the problem. It would be easier for you if you involve a team of relevant people for example, if you are investigating bottlenecks in a process, it would help to have the process owner and other experts for the analysis.įollow the steps below to conduct a successful root cause analysis.ĭefine the problem your organization is facing and gather data and evidence relevant to it and necessary to understand the current situation.Ĭreate a problem statement which should include information about the problem like the actual impact, potential impact, the focal point, etc. Root Cause Analysis StepsĪ root cause analysis may take several hours of your time. But before we get to that, let’s understand how to conduct a root cause analysis first. There are several root cause analysis tools and techniques that can be used in the investigation of a problem. It helps you to dig into the underlying causes of the situation, thus allowing you to find appropriate solutions for it. Root cause analysis is a method that helps understand the primary cause of a problem or why a problem occurred in the first place. In this post, we will look at what is root cause analysis, the root cause analysis steps, and root cause analysis tools. It helps dig deeper and find effective solutions. Many organizations use the root cause analysis when a problem or something unplanned happens that will interrupt their business processes. To understand what happened, you need to get to the bottom of things. Well-planned projects fail, processes break down and employees lose their productivity.
