W. Edwards Deming is associated with what Lean tool or technique?

• A. 5S
• B. VSM
• C. SPC
• D. PDCA

Answer: (D)

At the heart of this question is understanding how Deming approached continuous improvement. He is best known for the PDCA cycle—Plan, Do, Check, Act—a simple, repeatable loop used to test ideas, learn from the results, and spread successful changes. This cycle embodies a disciplined way to implement small experiments, study their impact, and refine processes based on what’s learned, driving ongoing quality growth. Other Lean tools have important roles too, but they’re not as directly tied to Deming’s name. 5S focuses on organizing the workspace, VSM (value-stream mapping) visualizes the flow of a product or service, and SPC (statistical process control) monitors process variation. While related to Lean and quality, PDCA is the mechanism most closely associated with Deming’s approach to continuous improvement.
