A product specification template teams can build from

Start with the user or business outcome, not the interface. State the current problem, who experiences it, what should become possible, and how the team will know the change helped. Add non-goals so adjacent ideas do not quietly enter the commitment.

Name every actor that can initiate, approve, observe, or be affected by the behavior. Distinguish a role from a persona: roles define capabilities and responsibility. For sensitive actions, state both who can act and who must not be able to act.

Write the smallest successful sequence from trigger to outcome. Then add branches at the point where a condition changes the behavior. Give each branch a condition and a destination; avoid burying alternatives in notes at the end.

List the entities the feature reads or changes. For new fields, record the type, required status, allowed values, default, and relationships. State important lifecycle transitions, retention expectations, and whether an action is reversible.

Do not copy an entire database schema. Include the product-level data contract that reviewers need to validate behavior and that implementers need to avoid incompatible assumptions.

Acceptance cases should prove the contract rather than repeat the happy path in different words. Include permissions, invalid input, duplicate requests, timeouts, and state conflicts where they are plausible. Give cases stable names so tickets and automated tests can refer back to them.

Record unresolved questions with an owner and the decision needed. Capture risks that could change scope or architecture, but keep general project management outside the product contract. When the revision is ready, name the approver and publish the accepted version before implementation treats it as authoritative.
