Lean Six Sigma Green Belt Certification Improve Phase and Solutions 5

Question 1

A Lean Six Sigma team is implementing a solution that changes a critical parameter setting. Which document should be updated FIRST to reflect the new standard?

Accepted Answer

Standard operating procedure (SOP)

Answer

The standard operating procedure must be updated first so that all operators follow the new, improved process consistently.

Question 2

What is the primary purpose of a 'confirmation run' after completing a DOE optimization?

Accepted Answer

To verify that the predicted optimal settings actually achieve the expected response in practice

Answer

A confirmation run tests the recommended optimal factor settings in real conditions to validate that the model predictions hold.

Question 3

Which Lean waste category includes unnecessary movement of people during their work?

Accepted Answer

Motion

Answer

Motion waste refers to unnecessary movement of people (e.g., walking, bending, reaching), while transport refers to the unnecessary movement of materials.

Question 4

In the context of solution implementation, 'force field analysis' is used to:

Accepted Answer

Identify driving forces that support change and restraining forces that oppose it

Answer

Force field analysis identifies the forces driving a change and those restraining it, helping teams strengthen drivers and reduce barriers.

Question 5

A team wants to reduce changeover time using SMED. After converting internal to external tasks, what is the next SMED step?

Accepted Answer

Streamline all remaining internal and external setup activities

Answer

After separating and converting setup activities, SMED's next step is to streamline (simplify and standardize) both internal and external tasks to further reduce time.
