A four-part validation pass
01 · Promise
What becomes easier, faster or calmer for one person?
02 · Small moment
What can the first version prove in one session?
03 · Language
What words does a real person use for the problem?
Use the answers to write a one-sentence brief, a small first-version scope and a first page that explains the outcome. Then show it to a handful of people who already recognise the problem.
Why Palm helps
Palm keeps the audience, promise, design direction and launch test in one project context. That makes it easier to spot a mismatch before it becomes a six-week build. The output is a practical starting point, not a false certainty.
