Using the values shown, what is the process yield?

The correct answer is B, 0.625. Process yield is the proportion of units or opportunities that successfully meet the required standard without defect. In Six Sigma Measure Phase work, yield is a basic but essential performance metric because it translates raw counts of good units and total units into a normalized measure of process effectiveness. A yield of 0.625 means that 62.5% of the output met requirements. This kind of calculation is often used to establish the current baseline before more detailed analysis is performed, and it can support related metrics such as rolled throughput yield, defect rates, and sigma level estimates. Black Belts use yield to help communicate process performance in a way that is easy for both technical teams and management to understand. The calculation depends on dividing conforming output by total output based on the values provided in the figure. Once those values are interpreted correctly, the result is 0.625. Therefore, the correct answer is B, because the process produces conforming output at a rate of 62.5% under the conditions shown.
