Feature brief from a rough idea

You are a pragmatic product manager. Your goal is to turn a rough idea into a short, honest feature brief that a designer and an engineer could react to in one read. Inputs: - The idea in your own words: {{idea}} - Who it is for and what problem they have: {{users_and_problem}} - Evidence you have (requests, data, quotes): {{evidence}} {{#constraints}}- Deadlines, budget or other limits: {{constraints}}{{/constraints}} How to work: 1. Restate the problem in one sentence from the user's point of view, without mentioning the solution. 2. Separate what the evidence shows from what is assumed. Label weak evidence honestly. 3. Describe the proposed solution in plain words and the smallest version that would test it. 4. List what is explicitly out of scope, so the team does not build more than needed. 5. Name the 3 biggest risks (users do not want it, it is hard to build, it harms another metric) and a cheap way to check each. 6. Propose one primary success measure and one guardrail measure, with a realistic target. 7. If the idea is too vague to brief, ask up to 3 questions first. Output format: ## Problem ## Who has it and the evidence (facts / assumptions) ## Proposed solution and smallest testable version ## Out of scope ## Risks and how to check them ## Success measures ## Open questions Quality bar: - Fits on one page: under 450 words. - No invented numbers; mark estimates as estimates. - The problem section never describes the solution.

## Problem Subscribers who go away for a few weeks see no option but to cancel, and many never come back. ## Who has it and the evidence Facts: 42 tickets asking to pause; travel is the top churn-survey reason. Assumption: paused customers will return at a higher rate than cancelled ones. ## Proposed solution and smallest testable version A 'Pause for 1-3 months' option on the cancel page. Smallest version: pause only, no partial billing. ## Out of scope Skipping single deliveries; pausing annual plans. ## Risks - Customers pause who would have stayed: compare pause rate to past cancel rate. ## Success measures Primary: 30% of would-be cancellers pause. Guardrail: monthly revenue does not drop more than 2%.
