IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 23

When a Belt implements an improvement that is automated thus requiring no particular understanding for use he has applied which Lean tool?

Answer options

• A. Mistake Proofing
• B. Kaizen Event
• C. 5S
• D. None

Correct answer: D

Explanation

The correct answer is D, as the question describes an improvement that is automated and does not necessitate understanding, which does not align with the other options. Mistake Proofing focuses on preventing errors, Kaizen Events are structured improvement sessions, and 5S is about workplace organization, none of which are solely about automation without user understanding.
