一个季度的需求,怎么排

「因为它重要」——所有人都这么说,那怎么排?

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.

按「重要性」排序永远排不出来,因为所有人都觉得自己那件事重要。这一份要逼出来的是四条真的能用的判据,其中第一条最反直觉:做完哪一件,你会知道一件现在不知道的事。

它会先让你排一遍,然后一条一条给判据、每给一条重排一次,最后拿你的两次排序对照 —— 看哪一件动得最多、为什么。

还有几件不好处理的会被单独拎出来问:老板提的、大客户要的、竞品刚上的、技术债和埋点。以及最后那一问:这个季度明确不做什么,说三件。

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.
