This Handbook is published to provide a compilation of significant policies and procedures applicable to the source evaluation and selection process. It provides guidance to source selection officials, source evaluation boards (SEBs), and others who will participate in the preparation of requests for proposals, evaluation of proposals, preparation of SEB reports, presentations to selection officials, and selection of offerors. The SEB process is a process utilized by the DOE to evaluate proposals submitted in response to formal requests for proposals above a specified dollar amount. The objectives of the process are to: (1) assure efficient and effective expenditure of Government funds; (2) optimize the opportunity for attainment of program objectives; (3) obtain adequate and effective competition in the acquisition of goods and services; (4) assure impartial, equitable, and thorough evaluation of proposals and other informaion received; and (5) provide necessary data to the source selection official to permit the selection of the best offer. The provisions of this Handbook will be used in appropriate major procurements as provided for in DOE Directives and Procurement Regulations and for other situations as determined by the Secretary, Deputy Secretary, or Under Secretary.
