Lean Six Sigma Yellow Belt (LSSYB) — Question 7

A Belt gathered the following defect data for a polyurethane production line and wanted to assemble it into a Pareto Chart. The correct order from left to right in the chart would be:

Data: Trimming 37 -

Forming 61 -

Packaging 29 -

Sealing 5 -

Answer options

• A. Trimming, Packaging, Sealing, Forming
• B. Packaging, Trimming, Sealing, Forming
• C. Sealing, Forming, Trimming, Packaging
• D. Forming, Sealing, Trimming, Packaging

Correct answer: D

Explanation

The correct answer is D, as the defects are arranged in descending order of frequency: Forming (61), Trimming (37), Packaging (29), and Sealing (5). The other options do not reflect this order, which is essential for a Pareto Chart that emphasizes the most significant issues first.
