省料后次品增加，怎样解释选择
What should we change after this trial? Explain your plan.
试做发现新排布省了布，但部分布袋提手太窄，五个袋子未通过检查。采购建议买更薄的布继续省钱，你要解释为什么先修正排布。
1 · 先听见真实对话
Colleague: What should we change after this trial?
You: We should fix the handle design first.
Colleague: Why do rejected bags matter?
You: Rejected bags create waste because we cannot sell them.
Colleague: How should we compare unit cost?
You: We should compare unit cost for good bags only.
2 · 理解表达在这里做了什么
material waste
materials we throw away
We need to reduce material waste.
这里指材料损耗；时间浪费可以用 wasted time，不能直接套 material。bottleneck
the slow step that holds up the rest
Packing is the production bottleneck.
不是所有慢任务都是瓶颈；它必须限制整体流程的产出。unit cost
the cost of making one item
Our unit cost is six pounds.
单位成本与总支出不同；比较时要一致地计算成本和产量。3 · 跟读后，换成自己的信息
We should fix the handle design first.
选择：先解决已经发现的质量问题。
Rejected bags create waste because we cannot sell them.
理由：次品不能销售，也是浪费。
We should compare unit cost for good bags only.
比较：只比较合格袋子的单位成本。
Once quality is stable, we can check the packing bottleneck again.
顺序：质量稳定之后再处理产出限制。
保留沟通意图，换掉人物、文件或时间。简单而准确的句子同样有效。
