![]() ![]() ![]() Eventually, reduce the number of defects reported over time.Prevent the reoccurrence of the same problem in the future.Advantages Of Root Cause AnalysisĮnlisted below are some of the benefits, you will get: Hence, the process of digging to the bottom of the issue is called Root Cause Analysis. Leaves and trunk which are above the ground are visible, but roots which are under the ground aren’t visible and roots grow deeper and can spread further more than we expect. Leaves, trunk, and roots are the most important parts of a tree. It is different from defect analysis, troubleshooting, and other problem-solving methods as these methods try to find the solution for the specific issue, but RCA tries to find the underlying cause. So, RCA is aimed at finding the root cause and not treating the symptom, by following a specific set of steps and associated tools. The same logic applies to Root Cause Analysis performed in any industry. He will continue the diagnosis and study until he narrows down to the root cause of the patient’s sickness. If the root cause of the disease is still unknown, the doctor will refer for scan tests to understand further. Then he will refer to laboratory tests to analyze the root cause of the disease. The doctor will first understand the symptoms. Hence it is used in multiple industries like Software Sector, Manufacturing, Health, Banking Sector, etc.Ĭonducting Root Cause Analysis is similar to the work of the doctor who treats a patient. RCA is not only used for defects reported from a customer site, but also for UAT defects, Unit Testing defects, Business, and Operational process-level problems, day-to-day life problems, etc. This will ensure that the defect or similar kinds of defects are not repeated. Based on the decision of RCA, we can enhance our Test Bed and include those production tickets as Regression Test cases. We can do RCA on production defects as well. RCA should not be limited only to testing the defects. Similarly, if we find that a defect was due to testing miss, we can review our test cases or metrics, and update it accordingly. If we find, that a defect was due to design miss, we can review the design documents and can take appropriate measures. When RCA is done accurately, it helps to prevent defects in the later releases or phases. We brainstorm, read and dig the defect to identify whether the defect was due to “ testing miss”, “ development miss” or was a “ requirement or designs miss”. RCA (Root Cause Analysis) is a mechanism of analyzing the Defects, to identify its cause. #5) Implement Root Cause Preventive Action (RCPA).#4) Implement Root Cause Corrective Action (RCCA).
