Which of the following tools is most appropriate for understanding why products fail?
Correct Answer: D
Understanding why products fail requires identifying the root causes of the failure. The most appropriate tool for this is Root Cause Analysis (RCA):
* Root Cause Analysis (RCA): RCA is a systematic process for identifying the fundamental causes of problems or failures. It helps to determine what happened, why it happened, and how to prevent it from happening again.
* Run Chart and Control Chart: These are used for monitoring process performance over time but do not specifically identify causes of failure.
* Pareto Analysis: This helps prioritize issues based on their frequency or impact but does not identify the underlying causes.
