满意度 4.6 分

满意度 4.6 分,8000 份问卷。你先问什么?

Copy the prompt, then pick a model. It plays the interviewer and asks you through it scene by scene instead of handing you the answer.

On a phone with the app installed, the system opens the app directly. Links cannot open external apps inside WeChat — open it in a browser first.

The copied text ends with the answer key the model grades you against. Don't read it yourself first — working it out on your own is the point.

这一份追的第一件事是:谁答的。 8000 份听着不少,回收率 2%;而最不满意的那批人早就走了,或者根本懒得答 —— 主观打分天然是「还愿意跟你说话的人」的分数。

然后它给你一张分布表:72% 给了 5 分,9% 给了 1 分。平均值 4.6 把这 9% 抹平了,而那 9% 是这份数据里唯一值钱的部分。

第三幕问那个不舒服的问题:只在用户体验最好的那一刻弹问卷,算作弊吗?判据是什么? 多数公司把这件事叫优化。

How to use this

There is no model answer here — but there are definite wrong answers. Only three things make a case hold up, and every prompt's answer key carries a "common wrong answers" section that is more useful than the checklist itself.

The three things that make it hold up

  1. You can say whose problem this is and what it is — **with evidence** (not "I think users would want it")
  2. You can say what success looks like — **and what that number is today** (no baseline, no acceptance criteria)
  3. You can name the cost and what you gave up — **the hardest one to fake**, which is why every prompt hunts for it

How to start

  1. Pick a question, open it, copy the prompt.
  2. Paste it into a brand-new conversation — not one where you already discussed it.
  3. Say nothing. Wait for its first question.

Four commands you can call out at any time

  • 跳过 move to the next scene now
  • 提示 give a direction, not the answer
  • 直说吧 spell this point out in full, then keep pressing on the trade-offs
  • 复盘 jump to the wrap-up and print the review card

Three traps

  • Don't rush to a solution. More than half the lost points here come from designing before asking — especially describing features before defining what success means.
  • Expect to be pushed for numbers. "It'll perform better", "users will like it" get cut off: which metric, what is it today, and when do you look?
  • When it starts praising you, point it back to rule five — feeling validated crowds out noticing what you missed.

Start with the north star metric; it underpins everything else. Then pick by what's on your plate: a backlog you can't order → prioritisation; nobody using it or retention sliding → retention and onboarding; need to price something → pricing. Save the experiment review for later, and keep redoing the one about turning a one-line request into a spec — it's the closest to daily work.
