Question 1

Which tool is used in the Improve phase to systematically evaluate potential solutions against weighted criteria?

Accepted Answer

Pugh matrix

Answer

A Pugh matrix compares solution alternatives against weighted selection criteria to identify the best option.

Question 2

What is the primary purpose of conducting a pilot test before full-scale implementation of an improvement?

Accepted Answer

To validate the solution on a small scale and identify unforeseen issues

Answer

Pilot testing validates that a proposed solution works effectively on a limited scale before committing resources to full deployment.

Question 3

In a designed experiment (DOE), what does a main effect represent?

Accepted Answer

The change in response caused by changing the level of one factor

Answer

A main effect measures the average change in the response variable when a single factor is changed from one level to another.

Question 4

Which Improve phase technique uses structured brainstorming to generate creative solutions by challenging assumptions?

Accepted Answer

SCAMPER

Answer

SCAMPER prompts teams to Substitute, Combine, Adapt, Modify, Put to other use, Eliminate, and Reverse elements to generate innovative solutions.

Question 5

What is a key risk of implementing multiple solutions simultaneously during the Improve phase?

Accepted Answer
