Yield
Yield turns up in 2 fields: statistics, forestry. Here is what it means to the people in each one.
Yield in statistics
Fraction of units that come out good at a step or across a whole process, the headline number for any production line.
Yield is good output divided by input, stated per step or end to end. Fabs track line yield (wafers surviving the process), die or sort yield (good die per wafer at probe) and final test yield, and multiply them for overall yield. Rolled throughput yield multiplies first-pass yields across every step, so ten steps at 98 percent each give only about 82 percent, which exposes rework that a final yield figure hides.
"Sort yield on the new product is stuck at 71 percent and the wafer maps all show the same edge ring."
Yield in forestry
The total volume or quantity of usable wood harvested from a forest stand.
Foresters calculate this metric to determine the harvestable timber volume produced over a specific rotation period. It is usually expressed in cubic meters, board feet, or tons per acre. Accurate projections help managers balance harvesting rates with natural growth to ensure long-term sustainability and profitability.
"The cruise indicates a projected yield of forty thousand board feet per acre for that second-growth pine stand."
