procurement improprieties were made, if the offeror does not suffer competitive prejudice, the protest won't be sustained in their favor. As a KO, you recently terminated a contract for default, but the funds have expired. Are you able to use those de-obligated funds? - Answers :If the government has terminated the contract for default (or cause in the case of a commercial contract), the government can use the original funds for a replacement contract, even if the funds have expired, as long as these conditions apply: The contract was made in good faith A continuing bona fide need exists The replacement contract is of the same size and scope as the original contract The replacement contract is awarded without undue delay after the original contract is terminated for default The replacement contract is awarded to a different contractor The COR has noticed that the contractor may be acquiring "Contractor Acquired Property" (CAP) that was authorized for purchase in the contract. The contractor reportedly told the COR that they were not tracking the purchase or the location, etc., of the property because they (contractor) purchased it, not the Government. What would you do in this instance? - Answers :Would have to review the contract to determine what type of contract it is, ie: FFP or cost. In accordance with the FAR, typically the Government has title to the contractor acquired property, but it depends on contract type and what is in the contract. See below for the different scenarios based on contract type. Government-furnished property also includes contractor-acquired property if the contractor-acquired property is a deliverable under a cost contract when accepted by the Government for continued use under the contract. Under fixed - price type contracts, in the absence of financing provisions or other specific requirements for passage of title in the contract, the contractor retains title to all property acquired by the contractor for use on the contract, except for property identified as a deliverable end item. If a deliverable item is to be retained by the contractor for use after inspection and acceptance by the Government, it shall be made accountable to the contract through a contract modification listing the item as Government-furnished property. Under cost type and time-and-material contracts, the Government acquires title to all property to which the contractor is entitled to reimbursement. If it is FFP and there was no deliverable, it may not matter that they are not tracking it for our purposes because we don't have title to it, however we paid for it, so there should be some record of it for invoicing purposes. Otherwise, if it is cost, we should have the rights. Would probably also set up a telecom with the customer, COR, legal, and the contracts to discuss and would follow up with a PCO letter to advise them that it is their responsibility to track the equipment, etc. Describe the difference between an OTA vs. a FAR based contract. - Answers :Other Transaction Authority (OTA) Contract is used for DoD or military services that need access to research and development projects or prototypes from commercial sources but require more flexibility than the traditional government acquisition process allows. OTAs can take many forms, most are used to build systems prototypes outside the

Federal Acquistion Regulations. They are especially ideal for creating and promoting new technologies from nontraditional sources. FAR based contracts are using Federal Acquisition Regulations and DFAR supplements as a procurement mechanism to purchase property of services for its use. These are governed by strict terms and conditions. Explain what strategic sourcing is. Are you aware of any strategic sources? How is this related to recent policy to conduct and submit a Business Case Analysis (BCA) for review and approval? What dollar thresholds apply to this requirement? - Answers :The collaborative and structured process of critically analyzing an organization's spending and using this information to make business decisions about acquiring commodities and services more effectively and efficiently. In order to develop strategic sourcing, there has to be a Business Case Analysis to see what the benefit of strategic sourcing is. Example of strategic sources are GSA, CHESS, OASIS. You receive a pricing report (inclusive of the technical evaluation) for a government recommended position on direct labor costs which reflects an amount that is significantly lower than the proposed amount. What might you rely upon in the development of your objective position and/or what you might seek during negotiations to support a movement towards an objective position? - Answers :Wage Determination, industry standards in the area, union agreement, and experience level available in the area What is the role the contracting officer in a formal source selection environment as it relates to the SSEB, Source Selection Advisory Council (SSAC), and Source Selection Authority (SSA)? Include a discussion of the primary activities and acquisition documents that the contracting officer is responsible for. - Answers :1.

The contracting officer will advise and assist the SSA and SSAC Chair in the execution of their responsibilities. (DoD SSG)

You receive a letter from a contractor requesting a no cost time extension. The contractor states that he is behind schedule due to his subcontractor's slow progress. The requiring activity concurs with the request for the extension and recommends that it be processed as an "Excusable Delay". He says it is an "Excusable Delay" because the delay is not the fault of the prime contractor.
