Which of the following is NOT considered a process tool?

The correct answer, which identifies patient interviews as not being considered a process tool, is accurate because patient interviews are primarily methods of data gathering or qualitative assessment rather than a structured process tool. Process tools are generally aimed at helping to visualize, analyze, or improve processes, and they often provide frameworks or systems for continuous improvement.

Graphs and charts are visual representation tools commonly used to display data and trends, helping teams to interpret information at a glance and make informed decisions. PDCA, or Plan-Do-Check-Act, is a well-established process improvement methodology that provides a structured approach to problem-solving and quality improvement initiatives.

In contrast, patient interviews, while valuable for gathering insights and understanding patient experiences or needs, do not directly provide a processing framework or methodological structure to analyze and enhance workflows systematically.
