Question 1

A team uses a Pugh Concept Selection Matrix to evaluate solutions. What is the primary purpose of this tool?

Accepted Answer

To compare multiple solution alternatives against weighted criteria

Answer

The Pugh matrix scores competing solutions against evaluation criteria, helping teams select the best option objectively.

Question 2

During a kaizen event, the team identifies a process step that adds no value. According to Lean principles, what should they do first?

Accepted Answer

Eliminate the step if possible

Answer

Question 3

A solution pilot is run on one production line before full rollout. What does the pilot primarily validate?

Accepted Answer

That the solution is feasible and achieves the desired improvement

Answer

A pilot tests solution feasibility and effectiveness at small scale before committing to full implementation.

Question 4

Which improvement tool is best suited for reducing changeover time between product runs?

Accepted Answer

SMED (Single-Minute Exchange of Die)

Answer

SMED is a Lean technique specifically designed to reduce equipment changeover and setup times.

Question 5

A process improvement reduces average cycle time from 12 minutes to 8 minutes. What is the percentage improvement?

Accepted Answer
