Which of the following can be an effective tool during quality control to help determine the how the problem occurred?

Rework is a corrective action applied after a defect is identified, not a diagnostic tool for determining how the problem occurred.

A flowchart visually depicts the sequence of steps in a process, allowing analysts to trace the path leading to a defect and pinpoint exactly where the breakdown occurred. This makes it especially effective for understanding the root cause and mechanism of a problem, not just its frequency or outcome.

Trend analysis examines performance data over time to forecast future results, not to diagnose the cause of a specific defect.

A Pareto diagram ranks defect types by frequency to prioritize which problems to address first, but does not explain the process path that caused the issue.
