不良品が増えて歩留りが下がったので、製造ラインを見直した。

USAGE:
A technical term used in manufacturing and food processing. In cooking, it refers to the usable portion after trimming (e.g., the edible percentage of a fish after removing bones and skin). In semiconductor manufacturing, it measures the percentage of chips that pass quality testing.
COMMON COLLOCATIONS:
- 歩留りが高い/低い (yield is high/low)
- 歩留りを上げる (to increase yield)
- 歩留りを改善する (to improve yield)
- 歩留り率 (yield rate — explicit percentage form)
ETYMOLOGY:
Originally from rice milling — 歩 (rate, percentage) + 留り (remaining), describing how much usable white rice remains after husking.
