Next Big Idea — start with the Why
Next Big Idea is where a project begins. It lives in the Look & Listen phase and exists to do one thing well: get you to start with the Why before you start building. Name what you want to try, and be honest about why it matters — to you and to the customer.
What it captures
| Field | What goes here |
|---|---|
| Start with the Why (required) | Why this matters at all — the problem worth solving. |
| Why is this important to you? | Your own motivation. The fuel that keeps you going when it's hard. |
| Who is your customer? | The person you're solving it for. |
| Why is this important for them? | The pull on their side — the reason they'd care. |
| What do you want to try? | The idea itself, in plain words. |
Only the Why is required. Everything else is there to sharpen your thinking, not to slow you down — fill what's clear and come back for the rest.
Challenge my idea
The tool ships with one Sandai action: Challenge my idea. It plays devil's advocate — naming the single riskiest assumption behind your idea and one cheap way to test it this week. It's read-only feedback; it doesn't change your words.
Use it the moment your idea feels exciting. The goal isn't to talk you out of it — it's to surface the leap of faith you'd otherwise discover the expensive way. If the call-out is worth keeping, hit Add as Note to save it as its own artefact right next to your Next Big Idea, instead of just copying it out.
Where it fits
- It's the first stop in the LEARN loop: frame the why before you model the what in Elaborate & Evaluate.
- Starting a project through Quick start with Sandai seeds your Why straight into a Next Big Idea artefact, so you're never staring at a blank page.
- Pair it with the Idea Pitch to turn that Why into a sharp, shareable one-liner.
A common flow: capture the Why here, run Challenge my idea to find the riskiest assumption, then design a small experiment to test it.
