Congress has broad authority to impose requirements upon the federal procurement process, or the process whereby agencies obtain goods and services from the private sector. One of the many ways in which Congress has exercised this authority is by enacting measures intended to promote contracting and subcontracting with \"small businesses\" by federal agencies. This book describes and analyses measures that Members of the 112th Congress have enacted or proposed in response to particular issues pertaining to small business contracting and subcontracting with a focus on legal authorities; contract \"bundling\"; small business set-aside programs; and \"preference contracts\".
