What Belongs Here
The Product Brief answers five strategic questions:
- Why does this product exist? (Vision & business goals)
- Who is it for? (Target users and their context)
- What does it need to do? (Core capabilities)
- How will we know it works? (Success metrics)
- What are the constraints? (Platform requirements, tech stack)
Everything downstream — trigger maps, scenarios, page specs, design system — traces back to decisions made here. This is the North Star.
