Root Cause Analysis (RCA)

Root Cause Analysis (RCA) is a systematic process for identifying the underlying reasons for a problem or defect to prevent its recurrence. The process begins with clearly defining the issue, including when, where, and how it occurs. Relevant data, such as logs and user reports, are then gathered to understand the problem's context. Techniques like the "5 Whys" or Fishbone Diagram are used to drill down to potential root causes, which are then analyzed to determine the most likely root cause by verifying the cause-effect relationship.

Once the root cause is identified, corrective actions are developed to address it, which might include process changes or code fixes. These solutions are implemented and monitored to ensure the problem is resolved. Finally, findings, solutions, and lessons learned are documented and communicated to stakeholders to prevent similar issues in the future.

RCA is crucial for continuous improvement, helping organizations enhance processes, reduce future problems, and achieve more sustainable solutions by systematically addressing the root causes of issues.
