CDRL1

CDRL1 is a designation used in contract data management to identify the first item in a Contract Data Requirements List (CDRL) within government or defense procurement. The CDRL is a contractual mechanism that specifies data deliverables the contractor must provide to the contracting activity. While CDRL1 refers specifically to the initial data item, its exact nature depends on the contract and can include technical reports, design documents, test results, software codes, or other contractor data.

A CDRL item, including CDRL1, is defined by its data item description (DID) reference, which provides the formal specification for the deliverable. The item will describe the required content, formatting, and any mandatory standards or templates, as well as delivery timing, media, and submission method. It also sets acceptance criteria and the authority responsible for review and approval. Security classifications, distribution restrictions, and rights to use or reproduce the data may be specified as part of the item.

In practice, CDRL1 serves as a binding obligation within the broader contract, aligning data production with program milestones and review points. The contractor is expected to prepare the data in accordance with the referenced DID, deliver it on schedule, and obtain formal acceptance if required. If data are late, incomplete, or nonconforming, remedies or contract adjustments may apply as defined in the agreement.

CDRL1 is one example within a broader set of data deliverables used to ensure traceability, compliance, and support for program decision-making and validation activities.
