Product Specification
- Start from the management or user outcome.
- Define scope, non-goals, users, roles and terminology.
- Describe current and target behaviour.
- Define workflows, statuses, business rules, permissions, data, integrations,
reporting and complete failure states.
- Write acceptance criteria that are observable and testable.
- Trace every feature to a decision or requirement.
- Separate launch requirements from later options.
- Record assumptions and unresolved decisions.
Required outputs may include:
PRD | BRD | FRS | User stories | Acceptance criteria
Information architecture | Role model | Status model | KPI catalogue | Tickets
A specification is complete when implementation and verification can proceed
without inventing material behaviour.
