IASSC Certified Lean Six Sigma Green Belt (ICGB) — Question 24

A Belt concludes a Lean Six Sigma project with the creation of a Control Plan. At what point can the Control Plan be closed?

Answer options

• A. Never, a Control Plan is a living document
• B. As soon as the Champion signs off
• C. Within 30 days of the LSS project review team meeting
• D. After the project has been presented at the recognition event

Correct answer: A

Explanation

The correct answer is A because a Control Plan is designed to be an ongoing, adaptable document that evolves as processes improve or change. The other options suggest closure points that do not align with the purpose of a Control Plan, which is to continuously monitor and control processes.
