Accepted Answer

Control

Answer

The Control phase in DMAIC ensures that improvements are sustained through monitoring plans, control charts, and updated standard work.

Question 2

Which waste category in the 8 wastes of lean describes producing more than the next downstream process or customer immediately needs?

Accepted Answer

Overproduction

Answer

Overproduction is often called the 'mother of all wastes' because it creates or hides other wastes like excess inventory, waiting, and transportation.

Question 3

A team uses error-proofing devices to make defects physically impossible or immediately detectable. The lean term for this approach is:

Accepted Answer

Poka-yoke

Answer

Poka-yoke refers to mistake-proofing mechanisms that prevent errors from occurring or that detect them instantly at the source.

Question 4

During value stream mapping, a 'push' arrow between two process boxes indicates:

Accepted Answer

Material is pushed forward based on a schedule or batch completion

Answer

A push arrow shows that material is produced and forwarded to the next step regardless of downstream demand, a common source of overproduction.

Question 5

A lean practitioner wants to reduce changeover time from 3 hours to under 10 minutes. The BEST framework to apply is:

Answer

SMED systematically converts internal setup steps to external ones and streamlines remaining internal steps to dramatically cut changeover time.
