Before the start of a large, cross functional change effort the team of Business analysts (BAs) assigned decided they need something to help them ensure requirements collectively support one another a

Process modeling maps how work actually flows through an organization, making it possible to see how individual requirements interact across functional boundaries and surface any contradictions or gaps. In a large cross-functional effort, these models serve as a shared reference that the team can inspect to confirm requirements align end-to-end. This technique is specifically suited for checking collective consistency, not just individual requirement correctness.

Functional decomposition breaks high-level functions into sub-functions but does not represent the interactions or dependencies between requirements needed to detect conflicts.

Template architecture provides structural scaffolding for documentation but does not analytically evaluate whether requirements support or contradict each other.

A checklist is useful for verifying known criteria against a fixed list but lacks the relational, workflow-level view needed to discover cross-requirement conflicts.
