INVEST Criteria

When writing a User Story, keep the INVEST criteria in mind:

Independent: The story can be developed and delivered on its own, without dependencies.

Negotiable: The story is open to discussion and refinement, not a rigid contract.

Valuable: The story provides clear value to the user or customer.

Estimable: The story is defined enough to estimate the effort required.

Small: The story is manageable and can be completed within an iteration.

Testable: The story has clear acceptance criteria, making it easy to verify completion.
