Question 4

Which of the following describes the primary purpose of a Poka-Yoke (mistake-proofing) solution in the Improve Phase?

Accepted Answer

To eliminate the possibility of human error by design.

Answer

To visually display process performance over time.

Answer

To gather customer feedback on new process designs.

Answer

To quantify the relationship between input and output variables.

Question 5

A Green Belt team has implemented a new training program to reduce errors in a data entry process. Before fully rolling out the solution across the entire department, they decide to run the new process in a small, controlled environment to test its effectiveness and identify any unforeseen issues. This approach is best known as:

Accepted Answer

Pilot implementation

Answer

Full-scale deployment

Answer

Process mapping

Answer

Measurement System Analysis

Accepted Answer

Developing a detailed implementation plan, including resources, timeline, and responsibilities

Answer

Creating a SIPOC Diagram

Answer

Conducting a Measurement System Analysis (MSA)

Answer

Brainstorming more root causes
