Use & Relationship
Using system models, the Reliability and Maintainability (R&M) Allocation Report documents the methods and results of the allocation of the reliability, maintainability and Built-In Test (BIT) requirements. End item quantitative requirements must be broken down to appropriate system/subsystem/unit levels necessary to establish requirements for designers and subcontractors.
This Data Item Description (DID) contains the format, intended use information, and content preparation instructions for the data product generated by the specific and discrete task described in the solicitation or contract.
This DID should be tailored appropriately to each program.
