What procedure is used to determine the cause of a defective product or a nonconforming process?

Root Cause Failure Analysis is the procedure specifically designed to identify the underlying reasons or causes for a defective product or a nonconforming process. This approach systematically investigates failure points in order to understand what went wrong, focusing on identifying not just the symptoms but the fundamental issues that can lead to these failures. By digging into the root causes, organizations can implement effective corrective actions that prevent future occurrences of similar problems.

The goal of this analysis is to develop a deeper understanding of the processes involved and to ensure that effective measures are put in place to address the core issues, rather than simply treating the symptoms of the defects. This thorough investigation helps improve overall quality and reliability in manufacturing processes, leading to fewer defects in the long run.

Other options, while related to quality and defect management, do not specifically focus on determining the root cause in the same comprehensive manner as Root Cause Failure Analysis.
