Question 1

A team wants to implement mistake-proofing on an assembly line. What Lean term describes this approach?

Accepted Answer

Poka-yoke

Answer

Poka-yoke refers to mistake-proofing devices or methods that prevent errors or make defects immediately detectable.

Question 2

During solution implementation, which stakeholder communication approach is most effective for reducing resistance?

Accepted Answer

Involving key stakeholders early and updating them throughout the process

Answer

Engaging stakeholders early and maintaining ongoing communication builds trust and reduces resistance to change.

Question 3

A Yellow Belt team proposes increasing inventory buffers to prevent stockouts. A lean practitioner would likely challenge this because:

Accepted Answer

Excess inventory is considered a waste that hides other process problems

Answer

Lean views excess inventory as waste (muda) because it consumes space and capital while masking underlying process instability.

Question 4

What does a 'future state' value stream map represent in the Improve phase?

Accepted Answer

The ideal process design after waste is eliminated

Answer

The future state map depicts the redesigned process with waste removed, serving as the implementation target.

Question 5

A team runs an A/B test comparing two process configurations. After the test, the new configuration shows a statistically significant improvement. What should be the next step?

Accepted Answer

Develop an implementation plan to roll out the improved configuration

Answer

Once a solution is validated with statistical significance, the team should plan and execute full-scale implementation.
