I am a CO managing a large dollar Contract (CPAF, term level of effort, services). Is it proper to direct the contractor to move scope back and forth, or in and out of the Contract’s underlying performance measurement baseline, on the basis of Federal program manager priorities associated with the ever changing budget? Usually this practice will result in some changed work for which I issue change orders. Second question, given the above culture of Federal managers moving scope around, if the contractor agrees to no change in cost or fee for the changed work portion, is it allowable to not go through the change order administration process of certified cost proposal, review, definitization? I am new to award fee contracting, but previously managed a CPIF completion contract, and there was no “scope swapping” activity, but there were plenty of directed change orders to administer. Thanks
