What is meant by "root cause analysis" in QA?

Root cause analysis in Quality Assurance refers to a systematic approach aimed at identifying the fundamental cause of defects or issues in a product or process. This methodology emphasizes understanding the underlying reasons for failures, ensuring that organizations can take corrective actions to prevent recurrence. By focusing on the root cause rather than just addressing the symptoms, QA professionals can implement more effective solutions that enhance overall quality and reliability.

This analytical process often involves various techniques such as the “5 Whys” or Fishbone diagrams, which help teams delve deeper into issues to reveal their sources. Ultimately, the goal of root cause analysis is to improve processes, reduce defects, and enhance customer satisfaction by ensuring that underlying problems are resolved rather than just treated superficially.
