To write a PRD from a vague idea without assumptions, you need structured requirements discovery. Conducting a thorough pre-planning interview clarifies goals, users, scope, and business rules before drafting begins.

The best way to define product scope and functional requirements is through exhaustive discovery rounds. This process collects goals, scope boundaries, constraints, edge cases, and acceptance criteria to ensure complete coverage.

Yes, you can generate acceptance criteria and test strategy during requirements discovery. When the project produces code, code-aware coverage adds test strategy to ensure the resulting spec is actionable for engineering.

Structure a requirements interview in dedicated rounds covering goals, users, scope boundaries, functional requirements, business rules, constraints, and edge cases. A readiness gate prevents premature drafting until the idea is specific enough.

Requirements discovery works for aligning stakeholders by uncovering missing requirements early. It transforms an unclear idea into an assumption-light product spec that is fully ready for planning and implementation.

You should not use a pre-planning interview if your idea is already highly specific. The readiness gate prevents drafting until critical requirements are clear, making it unnecessary for fully defined product specs.
