RAS

A Requirements Allocation Sheet is a document that maps system or contract requirements to specific components, work packages, or responsible parties. RAS documents ensure traceability between high-level requirements and implementation elements, supporting verification that all requirements are addressed.

In systems engineering contexts, RAS tracks how parent requirements flow down to subsystem and component specifications. For service contracts, RAS may allocate performance requirements to specific labor categories or functional areas. Maintaining accurate requirements allocation supports configuration management, change control, and compliance verification throughout contract performance.
