Freedom from Government Competition Act of 2017 This bill requires each executive or military department or independent establishment to obtain all goods and services necessary for or beneficial to the accomplishment of its authorized functions by procurement from private sources, except if: (1) such goods or services are required by law to be produced or performed by such agency; or (2) the agency determines and certifies that federal production, manufacture, or provision of a good or service is necessary for the national defense or homeland security, that a good or service is so critical to the agency's mission or so inherently governmental in nature that it is in the public interest to require production or performance by government employees, or that there is no private source capable of providing the good or service. This bill requires such private sector provision of goods and services to be performed through: (1) the divestiture of federal involvement, (2) the award of a contract using competitive procedures, or (3) conducting a public-private competitive sourcing analysis in accordance with Office of Management and Budget (OMB) procedures and determining that using the private sector is in the best interest of the United States and provides the best value to the taxpayer. The bill authorizes an agency to utilize federal employees to provide goods or services previously provided by a private sector entity upon completion of a public-private competitive sourcing analysis and after determining that provision by federal employees provides the best value. The OMB must carry out a study to evaluate the activities carried out in each agency.
