Pick one answer per question. Explanations appear after you submit.

1. 1. A Pugh matrix should treat a legal safety requirement as:

   • Weighted score
   • A pass/fail gate before scoring
   • Bonus point
   • Optional

2. 2. Levels in DOE are:

   • Factor importance
   • Setting values tested for a factor
   • The response
   • The block

3. 3. Fractional factorial trades:

   • Nothing
   • Interaction resolution for fewer runs
   • Sample size for cost
   • Precision for time

4. 4. A pilot succeeded on one shift and one style. Rollout should:

   • Proceed
   • Extend the pilot to representative shifts/styles first
   • Skip control plan
   • Automate

5. 5. Solution FMEA is used to:

   • Reject solutions
   • Identify how the chosen solution can fail and add controls
   • Score creativity
   • Replace RCA

6. 6. Randomisation in an experiment:

   • Wastes time
   • Guards against unknown lurking variables and time trends
   • Only helps large samples
   • Is optional in DOE

7. 7. AHP is worth its complexity when:

   • Any decision
   • Criteria weights themselves are disputed and pairwise judgements clarify
   • Never
   • Only for cost decisions

8. 8. A pilot must define, before it starts:

   • The winner
   • Success, stop and rollback criteria with guardrails
   • The final cost saving
   • The vendor

9. 9. Practical significance in a pilot means:

   • p < 0.05
   • The effect is large enough to matter to the customer/process
   • R² > 0.9
   • Large n

10. 10. Cost-benefit that omits training and risk mitigation is:

    • Complete
    • Incomplete and misleading — include lifecycle costs
    • Standard
    • Approved by finance
