The BA Is finalizing the definition of the requirements architecture by understanding how requirements relate to each other. A key component that must be apparent in all three diagrams is that none of

Unambiguous is the quality criterion requiring that a requirement have only one possible interpretation and that its meaning and relationships to other requirements are clear and non-conflicting. When a BA verifies that no requirement is linked in different or conflicting ways across multiple diagrams, they are confirming that each requirement carries a single, consistent meaning - the defining characteristic of an unambiguous requirement.

Correct refers to the quality criterion that a requirement accurately represents a stakeholder's actual need, not whether requirement relationships are internally consistent across diagrams.

Necessary refers to the criterion that each requirement represents something genuinely required to achieve a business objective, not the consistency of how requirements are linked.

Defined is not a recognized standard requirement quality criterion in the BABOK framework - the established criteria include unambiguous, complete, consistent, correct, feasible, and necessary.
