Data Item Description(DID)
A document defining the content, format, and delivery requirements for a specific data deliverable referenced in CDRLs.
Overview
A Data Item Description (DID) is a standardized document that specifies the content, format, structure, and preparation instructions for a data deliverable required under a DoD contract. DIDs are referenced by CDRL line items (DD Form 1423) and provide the detailed guidance contractors need to produce compliant deliverables such as test plans, technical manuals, status reports, and engineering drawings.
Why It Matters in GovCon
DIDs define exactly what the government expects in each deliverable. Contractors who carefully review applicable DIDs during proposal preparation can more accurately estimate the effort required and avoid costly rework from non-compliant submissions. Tailoring DIDs — negotiating which sections are required — is a common practice that can reduce documentation burden.
Key Details
- ASSIST Database: DIDs are maintained in the Acquisition Streamlining and Standardization Information System (ASSIST) and identified by DI- prefix numbers.
- Tailoring: Government and contractors can negotiate which DID sections apply, with tailoring documented on the CDRL form.
- Content: Each DID specifies document title, content outline, format requirements, and any referenced standards.
- Contractor Format: When no DID exists, the CDRL may specify "contractor format," giving the contractor flexibility in document structure.
- Updates: DIDs are periodically updated; the contract references a specific version that remains in effect for the life of the contract.
