Which term refers to the process of measuring production efficiency by comparing the final output to the initial input as a ratio?

• A. Warehousing
• B. Wave picking
• C. Yield
• D. What-if analysis

Answer: (C)

The concept here is yield, which measures production efficiency as a ratio of good output to input. In manufacturing, you compare what you start with (input) to what you end up with as usable product (output). Yield is calculated as good units produced divided by units started. For example, starting with 100 raw units and ending with 95 acceptable units gives a yield of 95/100 = 95%. This concept captures both how efficiently the process converts inputs into usable products and how much is lost to scrap or defects. The other terms don’t fit this idea: warehousing is about storage, wave picking is an order-picking method, and what-if analysis is scenario planning.
