Steps
- Write a problem statement from your findings: who has the problem, what it is and the evidence. One short paragraph.
- List five to eight ideas that could address it, including at least one small idea and one that is not software.
- Score each idea with a simple method such as RICE: reach, impact, confidence and effort. Use your interviews for reach and impact, and be honest about confidence.
- Sort by score, then sense-check. Change the order only for a reason you can write down.
- Write a one-page brief: the problem, the users, the idea you would test first, what is out of scope, how you would measure success and your open questions.
- Write three user stories for the first idea, each with a reason ('so that') and acceptance criteria.
- Put the top ideas on a Now / Next / Later roadmap, with no dates beyond the next few weeks.
Tool examples
- Google Docs
- Use a shared spreadsheet with one row per idea and RICE columns.
