IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 70

A(n) ________________ has occurred when two inputs have a greater impact on a change in the output than either of the inputs has by itself.

Answer options

• A. Dependency
• B. Bimodal reaction
• C. Interaction
• D. Amplified effect

Correct answer: C

Explanation

The correct answer is 'Interaction' because it describes the phenomenon where combined inputs produce a greater effect than they would alone. The other options do not accurately represent this concept; 'Dependency' refers to reliance, 'Bimodal reaction' indicates two separate responses, and 'Amplified effect' suggests an increase but not necessarily a combined influence.
