For a dashboard that answers one question, should I build a complete plan first or test one small slice? I have limited time and I do not want throwaway work.
Gemini found the hole in my a dashboard that answers one question plan
This started as a messy question about a dashboard that answers one question. The follow-up made the answer practical.
Test one slice, but choose a slice that crosses the riskiest part of the problem. A tiny easy demo will only prove the easy part.
Use this decision rule:
- If reversing the choice is cheap, try it.
- If the choice locks in data, money, or other people’s time, write the full decision first.
- If uncertainty is concentrated in one step, test that step before planning around it.
For a dashboard that answers one question, make the first test produce evidence you can compare, not just something that looks complete.
That distinction between a small slice and an easy slice is useful.
