Defense Acquisition Challenge Program

(a)

Program Required .—

(1)
The Secretary of Defense, acting through the Under Secretary of Defense for Research and Engineering, shall carry out a program to provide opportunities for the increased introduction of innovative and cost-saving technology in acquisition programs of the Department of Defense.
(2)
The program, to be known as the Defense Acquisition Challenge Program (hereinafter in this section referred to as the “Challenge Program”), shall provide any person or activity within or outside the Department of Defense with the opportunity to propose alternatives, to be known as challenge proposals, at the component, subsystem, system, or system-of-systems level of an existing Department of Defense acquisition program, or to address any broader functional challenge to Department of Defense missions that may not fall within an acquisition program, that would result in improvements in performance, affordability, manufacturability, or operational capability of that acquisition program or function.
(b)

Panels .—

The Under Secretary shall establish one or more panels of highly qualified scientists and engineers (hereinafter in this section referred to as “Panels”) to provide preliminary evaluations of challenge proposals under subsection (c).
(c)

Preliminary Evaluation by Panels .—

(1)
Under procedures prescribed by the Under Secretary, a person or activity within or outside the Department of Defense may submit challenge proposals to a Panel, through the unsolicited proposal process or in response to a broad agency announcement.
(2)
The Under Secretary shall establish procedures pursuant to which appropriate officials of the Department of Defense may identify proposals submitted through the unsolicited proposal process as challenge proposals. The procedures shall provide for the expeditious referral of such proposals to a Panel for preliminary evaluation under this subsection.
(3)
The Under Secretary shall issue on an annual basis not less than one such broad agency announcement inviting interested parties to submit challenge proposals. Such announcements may also identify particular technology areas and acquisition programs or functions that will be given priority in the evaluation of challenge proposals.
(4)
(A)
The Under Secretary shall establish procedures for the prompt issuance of a solicitation for challenge proposals addressing—
(i)
section 4374 of this title any acquisition program for which, since the last such announcement, the Secretary concerned has determined under that the program’s acquisition unit cost or procurement unit cost has increased by a percentage equal to or greater than the critical cost growth threshold for the program (in this section referred to as a “critical cost growth threshold breach”);
(ii)
section 4375(b) of this title any design, engineering, manufacturing, or technology integration issues, in accordance with the assessment required by , that have contributed significantly to the cost growth of such program; and
(iii)
any functional challenges of importance to Department of Defense missions.
(B)
A solicitation under this paragraph may be included in a broad agency announcement issued pursuant to paragraph (3) as long as the broad agency announcement is released in an expeditious manner following the determination of the Secretary concerned that a critical cost growth threshold breach has occurred with respect to a major defense acquisition program.
(5)
Under procedures established by the Under Secretary, a Panel shall carry out a preliminary evaluation of each challenge proposal submitted in response to a broad agency announcement, or submitted through the unsolicited proposal process and identified as a challenge proposal in accordance with paragraph (2), to determine each of the following:
(A)
Whether the challenge proposal has merit.
(B)
Whether the challenge proposal is likely to result in improvements in performance, affordability, manufacturability, or operational capability at the component, subsystem, system, or system-of-systems level of an acquisition program.
(C)
Whether the challenge proposal could be implemented in the acquisition program rapidly, at an acceptable cost, and without unacceptable disruption to the acquisition program.
(D)
Whether the challenge proposal is likely to result in improvements to any functional challenges of importance to Department of Defense missions, and whether the proposal could be implemented rapidly, at an acceptable cost, and without unacceptable disruption to such missions.
(6)
The Under Secretary—
(A)
may establish procedures to ensure that the Challenge Program does not become an avenue for the repetitive submission of proposals that have been previously reviewed and found not to have merit; and
(B)
may establish procedures to ensure that the Challenge Program establishes appropriate priorities for proposals from businesses that are not major contractors with the Department of Defense.
(7)
If a Panel determines that a challenge proposal satisfies each of the criteria specified in paragraph (5), the person or activity submitting that challenge proposal shall be provided an opportunity to submit such challenge proposal for a full review and evaluation under subsection (d).
(d)

Full Review and Evaluation .—

(1)
Under procedures prescribed by the Under Secretary, for each challenge proposal submitted for a full review and evaluation as provided in subsection (c)(7), the office carrying out the acquisition program to which the proposal relates shall, in consultation with the prime system contractor carrying out such program, conduct a full review and evaluation of the proposal.
(2)
The full review and evaluation shall, independent of the determination of a Panel under subsection (c)(5), determine each of the matters specified in subparagraphs (A), (B), and (C) of such subsection. The full review and evaluation shall also include—
(A)
an assessment of the cost of adopting the challenge proposal and implementing it in the acquisition program; and
(B)
consideration of any intellectual property issues associated with the challenge proposal.
(e)

Action Upon Favorable Full Review and Evaluation .—

(1)
Under procedures prescribed by the Under Secretary, each challenge proposal determined under a full review and evaluation to satisfy each of the criteria specified in subsection (c)(5) with respect to an acquisition program shall be considered by the office carrying out the applicable acquisition program and the prime system contractor for incorporation into the acquisition program as a new technology insertion at the component, subsystem, system, or system-of-systems level.
(2)
The Under Secretary shall encourage the adoption of each challenge proposal referred to in paragraph (1) by providing suitable incentives to the office carrying out the acquisition program and the prime system contractor carrying out such program.
(3)
In the case of a challenge proposal submitted in response to a solicitation issued as a result of a critical cost growth threshold breach that is determined under full review and evaluation to satisfy each of the criteria specified in subsection (c)(5), the Under Secretary shall establish guidelines for covering the costs of the challenge proposal. If appropriate, such guidelines shall not be restricted to funding provided by the Defense Acquisition Challenge Program, but shall also consider alternative funding sources, such as the acquisition program with respect to which the breach occurred.
(f)

Action Upon Unfavorable Full Review and Evaluation .—

Under procedures prescribed by the Under Secretary, if a challenge proposal is determined by a Panel to satisfy each of the criteria specified in subsection (c)(5), but is not determined under a full review and evaluation to satisfy such criteria, the following provisions apply:
(1)
The office carrying out the full review and evaluation shall provide to the Panel that conducted the preliminary evaluation a statement containing a summary of the rationale for the unfavorable evaluation.
(2)
If the Panel disagrees with the rationale provided under paragraph (1), the Panel may return the challenge proposal to the office for further consideration.
(g)

Access to Technical Resources .—

(1)
Under procedures established by the Under Secretary, the technical resources of the laboratories, research, development, and engineering centers, test and evaluation activities, and other elements of the Department may be called upon to support the activities of the Challenge Program.
