This updated classic offers clear and concise explanations of the basic legal concepts of government contract law for professionals at any stage of their career. Written in straightforward language for contracting officers, contract administrators, contractors, subcontractors, and others in the procurement field, this new edition has been updated with new cases and regulations. The book breaks down the complex arena of government contract law into its three most basic parts: the contracting parties, the contract itself, and legal challenges. It begins by examining key aspects of the contracting officer's job and provides guidance for navigating its different and often conflicting demands. The government contractor's responsibilities and challenges are also outlined. Government contracts come in a lot more varieties than the typical commercial contract, and they also tend to be long and confusing. The second part of the book introduces the different types of legal agreements the government uses to buy the goods and services it needs—and addresses the challenges of writing a perfectly clear contract and guidelines for interpreting an ambiguous one. The book concludes with an overview of the government contract litigation process. This is an essential text for students preparing to do the work of government contracts, an indispensable guide for those new to the work, and a valuable reference for contracting personnel who seek solutions to specific issues they face in their day-to-day work.
