ASQ Certified Six Sigma Black Belt (CSSBB) — Question 14

Calculate the Rolled Throughput Yield of this process using this data.
Data: unit input: 1215, unit output: 1180, defects repaired: 184, scrap: 42

Answer options

• A. 80.85%
• B. 81.40%
• C. 82.23%
• D. 84.96%

Correct answer: B

Explanation

The Rolled Throughput Yield (RTY) is calculated by taking the total number of good units produced (unit output + defects repaired) divided by the total units input. In this case, RTY is (1180 + 184) / 1215, which equals approximately 81.40%. The other options are incorrect as they do not reflect the accurate calculation of the yield based on the provided data.
