What it does
Many product plans fail in two ways. The team builds something nobody wanted, or it keeps a roadmap that is just a list of features with dates. Nobody can say what each feature should change, so nobody can say when it worked. This workflow starts with the idea and rates the four risks: value, usability, feasibility and viability. It names an owner for each and picks the cheapest test for the riskiest one. Then it takes your feature list and turns each item into a problem for a named customer with one result you can measure. The order comes from Marty Cagan's article "The Four Big Risks" and his writing on teams that solve problems instead of shipping features.
You give it
- The idea, the problem it solves and who it is for
- What you already know, such as customer words, tests, costs and limits
- Customer reviews or messages (optional)
- Your brand file, for rules on claims and fit (optional)
- Your list of features, tasks or requests, with any dates
- Who asked for each item (optional)
- Brand brain (optional)
- Customer words (optional)
You get
- Each of the four risks with the evidence behind it, or marked unknown
- An evidence score out of 100, with the working shown
- An owner for each risk, the cheapest test for the riskiest one and the result that would change your plan
- Your list sorted into features, problems and results
- Three to five problems for named customers, each with one result to measure and a review point in place of a date
Use it when
- You have a product idea and want to know which risk to test first, before you spend on building.
- Your roadmap is a list of features and nobody can say what each one should change.
- A leader keeps asking for features, and you want to turn the requests into problems you can measure.
Steps
- Product idea risk checker: Paste your product idea and what you know. Get the four risks scored out of 100 and the cheapest first test.
- Product outcome roadmap planner: Paste your list of features and dates. Get a short list of problems to solve, each with a result to measure.
How to use it
- Download the handoff pack. It's a zip with HANDOFF.md and every skill file this workflow uses.
- Give the folder to Claude (in Claude Code, or as files in a Claude Project) and say "Follow HANDOFF.md".
- Paste your idea and your feature list. It works step by step and saves each result.
- Run the cheapest test on the riskiest risk, then bring back what you learn.
