MODEL, AND RISK MITIGATION EFFORTS

Pursuant to 52.215-210 Mission Suitability Volume Instructions section L.13, paragraph A.7, any Engineering Development Unit, Prototyping, Engineering Development Model, and associated Risk Mitigation Efforts proposed under Statement of Work Section 4 shall be documented in Attachment G of the model contract. These efforts are intended to mitigate schedule risk associated with High Risk engineering activities.

Stand-alone Engineering Development Units, Stand-alone Prototoype Units, and Prototyping within the EDM are not necessarily required under the contract and will not be construed as a weakness if not proposed. However, the Offeror may only receive credit in the mission suitability evaluation for the proposed efforts to the extent of its description in Attachment G and the associated benefits explained in its Mission Suitability Volume.

The Contractor shall clearly define what engineering development activities are to be accomplished as well as any products, analyses, tests, or reports that will be produced. Activities include but are not limited to:

• Efforts needed to help advance the engineering maturity of the concept employed in the design.

• Any component build to address a challenging engineering problem or to ensure confidence that the design can be qualified

• Development of a new engineering approach that supports assessing or reducing a risk posture.

• Engineering development effort intended to mitigate schedule risk associated with low Technology Readiness Level (TRL) items in order to achieve TRL 6 by PDR.

• Risk mitigation effort to demonstrate a new design concept or integration & test technique.

While the integrated Instrument EDM will not be subject to environmental qualification testing, the EDM may see specialized environments (e.g vibe, TVAC, EMI, thermal cycles) to enable demonstration of instrument functionality and performance.

The Contractor shall outline in Attachment G, an Engineering Development-and-Test Plan, identifying all items below:

a) the objectives of the stand-alone units and the EDM,

b) the functional and performance requirements from the contractual documents that the stand-alone units and any EDM will address,

c) the fidelity of the stand-alone units, including planned performance, environmental, and/or other testing for the stand-alone units,

d) any proposed combined stand-alone unit to stand-alone unit assembly and test plans

e) the proposed plan and level of fidelity of the EDM, including the plans for any additional stand-alone units that are needed to build a full EDM, if so proposed

f) any planned tests of the EDM, including the EDM CPT and EDM benchmark, along with any specialized environmental test conditions,

g) the risks planned to be mitigated/retired,

h) the schedule of stand-alone unit development and test, including linkages to

Engineering Peer Reviews, Milestone Reviews, Flight Unit subsystem fabrication and assembly, and the FM System integration schedules, and

i) the schedule of any EDM and its constituent components development and test, including linkages to Engineering Peer Reviews, Milestone Reviews, Flight Unit subsystem fabrication and assembly, and the FM System integration schedules.

Definitions

Brassboard: A medium-fidelity functional unit that typically tries to make use of as much of the final product as possible and begins to address scaling issues associated with the operational system. It does not have the engineering pedigree in all aspects but is structured to be able to operate in simulated operational environments in order to assess performance of critical functions.

Breadboard: A low-fidelity unit that demonstrates function only, without respect to form or fit.

It often uses commercial and/or ad hoc components and is not intended to provide definitive information regarding operational performance.

Engineering Development Unit (EDU): A high-fidelity unit that demonstrates critical aspects of the engineering processes involved in the development of the operational unit. EDUs are intended to closely resemble the final product (hardware and software) to the maximum extent possible and are built and tested to establish confidence and to validate that the design will function and perform as expected. Dependent upon its design and fabrication, the EDU may be subject to flight-like environments or environmental testing. EDUs cannot serve for environmental qualification, provide requirements verification, or be flown.

Engineering Development Model (EDM): At a minimum, an early build of the full instrument, providing full instrument functionality. The EDM may be comprised of some combination of Breadboard Unit, Brassboard Unit, Engineering Development Unit, and Prototype Unit hardware and software. The units of the EDM must be integrated electrically but need not be representative in form or fit to the flight model, e.g. structure. At a minimum, the ‘sensor unit’ portion of the EDM must be vacuum compatible. Dependent upon its design, fabrication, and intended purpose, the EDM may be subject to flight-like environments or environmental testing.

However, the EDM cannot serve for environmental qualification, provide requirements verification, or be flown.

Flight Model (FM): The complete, fully-assembled, instrument comprised of constituent Flight Units and inter-unit harnessing.

Flight Unit: The unit that will be flown. For GeoXO, the first Flight Units will be Protoflight Units with follow-on Flight Units subject to an Acceptance test program.

Protoflight Model (PFM): The complete, fully-assembled, first flight instrument comprised of constituent Protoflight Units and inter-unit harnessing.

Protoflight Unit: Flight hardware of a new design. It is subject to a Qualification test program that combines elements of Prototype and flight acceptance validation; that is, the application of design Qualification test levels and flight Acceptance test durations. First flight units of GeoXO hardware and software are subject to a Protoflight test program.

Prototype Unit: Flight hardware of a new design. The Prototype unit fully reflects the flight design to the maximum extent possible. It is fabricated with full reliability and quality-control measures, flight EEE parts, and may have full redundancy. The Prototype unit will be environmentally tested to full Qualification levels and durations and will be acceptance tested and fully calibrated in accordance with flight test procedures. Prototype units cannot be flown due to the over-stressing seen during environmental Qualification.

Qualification Unit: The Qualification Unit serves to qualify the design. Qualification is achieved through either a Protoflight or Prototype test program. For GeoXO, the Qualification Unit is the Protoflight Unit.
