DID (Data Item Description)

What is DID (Data Item Description)?

In government contracting, a Data Item Description (DID) is a critical document that outlines the specific requirements for deliverables a contractor must provide. It's a standardized format used by the government to clearly define what information or data is needed, how it should be presented, and the intended purpose of the deliverable. Without a proper DID, contractors risk delivering non-compliant work.

Definition

A DID is essentially a detailed instruction manual for a specific deliverable. It dictates the content, format, and any special instructions related to a specific data item required under a government contract. These data items can range from technical manuals and reports to software code and training materials. DIDs are most commonly used in contracts involving technical or complex deliverables, ensuring consistency and clarity. DIDs are documented in a Contract Data Requirements List (CDRL), also known as a DD Form 1423. If there's a dispute about a deliverable, the DID is the first document referenced to determine compliance.

Key Points

• Standardized Format: DIDs follow a standardized format to ensure consistency across different contracts and agencies. This format includes sections for scope, applicable documents, requirements, and preparation instructions.
• Deliverable Definition: The core function of a DID is to precisely define the deliverable. This definition encompasses all aspects, including content, format, and quality standards.
• Reference in Contract: The DID is referenced in the contract's CDRL, indicating which specific DID applies to each deliverable.
• Compliance Standard: DIDs serve as the standard against which the government evaluates the contractor's deliverables. Failure to meet the requirements outlined in the DID can lead to rejection of the deliverable.

Practical Examples

1. Technical Manual: A contract requires the delivery of a technical manual for a piece of equipment. The DID specifies the required sections, level of detail, diagrams, and safety information that must be included in the manual.
2. Software Code: A software development contract requires the delivery of source code. The DID specifies the coding standards, commenting requirements, and testing procedures that must be followed.
3. Training Materials: A training contract requires the development of training materials. The DID specifies the learning objectives, target audience, instructional methods, and assessment criteria for the training program.
