Product Design Scope Checklist

Founders, product teams, and operators turning an idea or messy interface into a build-ready product direction. Use this checklist before design or development starts. It clarifies which user flows, decisions, screens, states, and handoff details need design attention before engineering cost locks in.

Checklist

  • Define the users, jobs, moments of friction, and decisions the product supports.
  • Choose whether the work needs wireframes, prototype, visual UI, or design system.
  • Map primary flows, empty states, errors, permissions, and edge cases.
  • Identify conversion, activation, or workflow moments that need extra clarity.
  • Document component, responsive, accessibility, and handoff requirements.
  • Decide what must be validated before build starts.
How to use this

Use the checklist to improve decisions before build

Design should reduce build risk, not decorate unclear scope.

Edge cases are often where engineering surprises hide.

A prototype is useful only when it answers a decision the team needs to make.
