Attachment G: Desired Capabilities Questionnaire

Instructions

The following questionnaire is designed to assist the Government in understanding how an Offerors proposed approach will incorporate the list of currently desired capabilities. Offerors are encouraged to evaluate their proposals accurately, however the Government reserves the right to make final determination of their assessment of the Offeror’s proposed system against the criteria based on the information provided, or not provided, in their proposal. For each capability, the Offeror is requested to also provide either a justification, to allow the Government a better understating of what capability the Offeror is proposing rather than just a simple response to the desired capabilities. Justifications may reference other portions of the proposal to allow for overall brevity.

For each desired capability, the Offeror is asked to provide one of the following responses:

• ‘Meet Threshold’ – Means that the proposed system will provide capability either meeting, or exceeding, the capability requested by the Government at the threshold level. Specify if this will be demonstrated by PDR or CDR.

• ‘Meet Objective’ – Means that the proposed system will provide capability either meeting, or exceeding, the capability requested by the Government at the Objective level. If a system will meet both the threshold and objective this should be stated by ‘Meet Objective’ designation. Specify if this will be demonstrated by PDR or CDR.

• ‘Partially Meet’ – Means that the proposed system will provide the desired capability in a partial manner, such that it meets most of the threshold level capability but not all the requested attributes. Provide an explanation of what part is met and if it will be met by PDR or CDR.

• ‘Future Capability/Does Not Meet’ – Means that the proposed system will not provide the capability during PDR or CDR as currently requested. A description of any capability in that capacity, or the limitation of providing that capability, should be provided in the justification section.

• ‘Alternative Capability’ – Means that the Offeror believes that they have a design which will provide service equal, or better, then the desired capability requested by the Government. Note that this statement will need strong justification within the proposal.

• ‘Not Applicable’ – Means that the Offerors proposal will not have the specified component or other item per the capability such that the requested capability is not applicable to their system. Provide an explanation on why the capability is not applicable.
