Which step involves finding the root of the problem using charts, graphs, and trend studies?

• A. Explore
• B. Plan
• C. Diagnose
• D. Act

Answer: (C)

Diagnose is the step focused on pinpointing the root cause by analyzing data and trends. When you use charts, graphs, and trend studies, you’re moving beyond symptoms to understand what underlying factor or combination of factors is driving the problem. This data-driven analysis helps reveal patterns, variability, and correlations that indicate the real source, guiding you to an effective remedy rather than just a temporary fix. Tools like Pareto charts, control charts, run charts, histograms, and trend analyses are all aimed at uncovering that root cause, which is why this step is the best fit. Exploring gathers information to understand the issue, planning designs the solution, and acting implements changes, but none of those centers on identifying the true cause through data visualization in the same way.
