step icon Step 31 | Block 16 Entries (cont’d) Tailoring the DID


Tailoring the DID often causes confusion.

Tailoring is the process of reducing the scope (“tailoring down”) of a DID and obtaining only minimum essential technical data & computer software. This will reduce cost. Tailoring is indicated in Block 4 of the DD Form 1423 with a “/T” and described in Block 16.

The scope of the DID shall not be increased (tailored “up”). If necessary, use another DID.

Sometimes, DIDs with very little content information may be tailored in order to give the contractor specific instructions/clarification. This is not necessarily adding scope.

The key points are:

  1. The contractor shall not be required to submit data outside the scope of the DID.
  2. The contractor must understand what to deliver.
