IASSC Certified Lean Six Sigma Yellow Belt (ICYB) — Question 2

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:Trimming37 -

Forming61 -

Packaging29 -

Sealing5 -

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 because the defects should be arranged in descending order based on their frequency. Forming has the highest count at 61, followed by Trimming at 37, Packaging at 29, and Sealing at 5, which aligns with the order specified in option D. The other options do not reflect the correct descending order of defects.
