Sec.  15.001  Definitions.

    As used in this part--
    Deficiency is a material failure of a proposal to meet a Government 
requirement or a combination of significant weaknesses in a proposal 
that increases the risk of unsuccessful contract performance to an 
unacceptable level.
    Proposal modification is a change made to a proposal before the 
solicitation closing date and time, or made in response to an amendment, 
or made to correct a mistake at any time before award.
    Proposal revision is a change to a proposal made after the 
solicitation closing date, at the request of or as allowed by a 
contracting officer, as the result of negotiations.
    Weakness means a flaw in the proposal that increases the risk of 
unsuccessful contract performance. A ``significant weakness'' in the 
proposal is a flaw that appreciably increases the risk of unsuccessful 
contract performance.
