Root Cause Analysisīefore taking any example, we are going to know the tools used in RCA, for the problem statement i.e. You can follow the below 8 steps to do the proper RCA. Proper RCA will help you to address the root cause for formulating the action plan to resolve the problem. ![]() There are many improvement projects being implemented in manufacturing industries such as the six sigma project, Quality Circle project, Kaizen, and small group activity project, where RCA is a vital milestone to successfully achieve the project goal. RCA or root cause analysis is a very important methodology to identify the root cause of any problem, issues, defects, non-conformities, customer complaints, warranty analysis, variation, deviation, abnormal activities, etc. If the Action Plan will fully effective then the control mechanism and action plan need to the incorporated in relevant documents (e.g. Step Eight:Įffectiveness of CAPA: – After implementation of CAPA, Trend Analysis needs to be plotted to figure out the effectiveness of CAPA or Action Plan. Step Seven:Ĭlick here to know more about the CAPA Process.ĭownload. Thereafter we have to do the Why-Why Analysis of all individual significant causes until to get the Root Causes. ![]() All Significant causes need to be listed up. WeĪfter doing the hypothesis testing as per the above pattern, one or number of causes will come to the point as significant Causes.īefore you execute the root cause identification. To find out the significant causes among the three problems. Let Shrinkage has the three potential causesĪs High Pouring Temperature, Wrong Gating System Design, High CarbonĮquivalent. Will come from Pareto chart considering with its Principle rules). Shrinkage as the problem, which is coming under the 80% contribution (Decision ![]() Hypothesis test needs to be executed here to find out the significant reasons. Next, to apply the Pareto principle to identify the Problems among the set, those are coming under the 80% contribution.Īll Problems these are coming under the 80% contribution need to be plot the Fishbone Diagram individually to represent the Potential Causes.ĭownload. Represent The Potential Cause: – Now you have to plot the Pareto chart with the Present collecting data.
