What is the purpose of a 'handoff' or transition plan at the end of a DMAIC project?
Answer: To ensure the process owner and operators can sustain the improvements without the project team
A handoff plan ensures the process owner has the knowledge, tools, and authority to maintain improvements after the project team disbands.
Which type of control is generally considered the most robust for preventing defects?
Answer: Engineering or physical controls (mistake-proofing)
Engineering controls are the most robust because they prevent errors automatically without relying on human memory or compliance.
In the Control phase, a 'replication plan' refers to:
Answer: Applying successful improvements to similar processes or locations across the organization
A replication plan identifies other areas of the business where the same improvements can be implemented to multiply the benefit.
What does 'Sustain' (the 5th S in 5S) require from leadership?
Answer: Ongoing reinforcement, audits, and accountability to maintain standards
Sustain requires consistent leadership reinforcement through regular audits, recognition, and accountability to prevent backsliding.
When should control chart control limits be recalculated?
Answer: After a confirmed process change has been implemented and stabilized
Control limits should be recalculated only after a deliberate, confirmed process change so the chart reflects the new baseline performance.
A Yellow Belt project team has completed improvements and verified results. Which document most directly supports ongoing process stability monitoring?
Answer: Control chart with response plan
A control chart paired with a response plan provides real-time monitoring and pre-defined actions to maintain process stability.
What is a 'lessons learned' document in the context of the Control phase?
Answer: A record capturing what worked, what didn't, and recommendations for future projects
A lessons learned document captures insights from the project so future teams can benefit from the experience and avoid repeating mistakes.
