Imagine that you are working on a two-million-dollar procurement for the purchase of vehicles for the fleet of trucks and cars to be used by the U.S. Department of Homeland Security, Customs and Border Protection. These vehicles will be used for off-road driving on dirt roads in Arizona. Your manager has asked you to select the type of contract to be used for the vehicle purchase.Choose to respond to this scenario from a government or a contractor perspective. If you select government, then you will complete the assignment as if you are a government employee (or military personnel) receiving the proposal from the contractor. If you select contractor, then you will complete the assignment as if you are a contractor employee submitting a proposal to the government.
