48 CFR § 217.7403
Policy
November 17, 2020
DoD policy is that undefinitized contract actions shall—
(a) Be used only when—
(1) The negotiation of a definitive contract action is not possible in sufficient time to meet the Government's requirements; and
(2) The Government's interest demands that the contractor be given a binding commitment so that contract performance can begin immediately.
(b) Be as complete and definite as practicable under the particular circumstances.
