IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 2

Calculate the Rolled Throughput Yield of this process using this data.
DatA. unit input: 1450, unit output: 1390, defects repaireD. 320, scrap: 60

Answer options

• A. 71.33%
• B. 72.66%
• C. 73.79%
• D. 77.93%

Correct answer: B

Explanation

The Rolled Throughput Yield (RTY) is calculated by taking the output units, subtracting the defects repaired and scrap, and dividing by the unit input. In this case, the calculation yields an RTY of 72.66%, making option B the correct answer. The other options do not accurately represent this calculation.
