Lean Six Sigma Yellow Belt Certification Control and Sustainment Methods 5

Question 1

What is the main purpose of a 'transition plan' at the end of a Lean Six Sigma project?

Accepted Answer

To hand off ownership of the improved process and controls to the process owner

Answer

A transition plan formally transfers responsibility for sustaining the gains from the project team to the day-to-day process owner.

Question 2

Why is it important to establish a 'benefit realization review' several months after project closure?

Accepted Answer

To verify that the expected financial and quality improvements are being sustained over time

Answer

A post-project review confirms that gains held after the project team disengaged and helps identify if corrective action is needed.

Question 3

Which of the following best describes 'management review' as a sustainment tool?

Accepted Answer

Periodic structured reviews of key metrics to confirm the process remains in control

Answer

Management reviews provide oversight by regularly examining KPIs and control chart data to ensure improvements are maintained.

Question 4

A process that was improved 6 months ago is showing gradual performance degradation. This most likely indicates:

Accepted Answer

Controls were not adequately maintained or sustained after project closure

Answer

Gradual regression typically results from insufficient sustainment — controls not being enforced, SOPs not followed, or no ongoing monitoring.

Question 5

Which of the following actions best reinforces a culture of sustainment within a team?

Accepted Answer

Recognizing and rewarding adherence to new standards and continuous compliance

Answer

Positive reinforcement of compliant behaviors embeds the new standard into team culture, making sustainment self-reinforcing.
