A customer has provided a business analyst (BA) with many business requirements and some have inter-dependencies with other requirements. To ensure the requirements are delivered according to customer

A unique identifier helps track and reference individual requirements in a traceability matrix but does not define what conditions constitute successful delivery per customer expectations.

Priority indicates the relative order or importance of requirements for scheduling purposes but does not specify the conditions under which a requirement is considered successfully fulfilled.

Constraints define limitations imposed on the solution space but do not establish the verifiable conditions that must be met to satisfy the customer's specific expectations for each requirement.

Acceptance criteria establish agreed-upon, testable conditions that must be met before a requirement is accepted by the customer, directly addressing the risk of misaligned delivery. When requirements have interdependencies, documenting acceptance criteria for each one ensures that success is clearly defined across all related requirements, preventing ambiguity about what constitutes a fulfilled expectation.
