Lean Six Sigma Green Belt (LSSGB) — Question 12

For a Cpk value of 1.67 and Cp value of 1, what can be concluded?

Answer options

• A. This process is centered but contains variation
• B. Process is well centered and variation is also low
• C. Process is not centered and has wide variation
• D. There is a calculation error

Correct answer: B

Explanation

The Cpk value of 1.67 indicates that the process is capable and well-centered, while the Cp value of 1 shows that the variation is low. Options A and C misinterpret the Cpk and Cp values, and option D suggests a mistake in calculations, which is not the case.
