[Code of Federal Regulations] [Title 48, Volume 4] [Revised as of October 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 48CFR307.7106] [Page 25-26] TITLE 48--FEDERAL ACQUISITION REGULATIONS SYSTEM CHAPTER 3--HEALTH AND HUMAN SERVICES PART 307_ACQUISITION PLANNING--Table of Contents Subpart 307.71_Requests for Contract Sec. 307.7106 Statement of work. (a) General. A statement of work (SOW) differs from a specification and purchase description primarily in that it describes work or services to be performed in reaching an end result rather than a detailed, well defined description or specification of the end product. The SOW may enumerate or describe the methods (statistical, clinical, laboratory, etc.) that will be used. However, it is preferable for the offeror to propose the method of performing the work. The SOW should specify the desired results, functions, or end items without telling the offeror what has to be done to accomplish those results unless the method of performance is critical or required for the successful performance of the contract. The SOW should be clear and concise and must completely define the responsibilities of the Government and the contractor. The SOW should be worded so as to make more than one interpretation virtually impossible because it has to be read and interpreted by persons of varied backgrounds, such as attorneys, contracting personnel, cost estimators, accountants, scientists, educators, functional specialists, etc. The SOW must clearly define the obligations of both the contractor and the Government so as to protect the interests of both. Ambiguous statements of work can create unsatisfactory performance, delays, and disputes, and can result in higher costs. (b) Term (level of effort) vs. completion work statement. Careful distinctions must be drawn between term (level of effort) SOWs, which essentially require the furnishing of technical effort and which may include a report thereof, and completion type work statements, which require development of tangible items designed to meet specific performance and/or design characteristics. (See FAR 16.306(d) for distinction). (1) Term (or level of effort). A term or level of effort type SOW is appropriate for research where one seeks to discover the feasibility of later development, or to gather general information. A term or level of effort type SOW may only specify that some number of labor-hours be expended on a particular course of research, or that a certain number of tests be run, without reference to any intended conclusion. (2) Completion. A completion type SOW is appropriate to development work where the feasibility of producing an end item is already known. A completion type SOW may describe what is to be achieved through the contracted effort, such as development of new methods, new end items, or other tangible results. (c) Phasing. Individual research, development, or demonstration projects frequently lie well beyond the present state of the art and entail procedures and techniques of great complexity and difficulty. Under these circumstances, a contractor, no matter how carefully selected, may be unable to deliver the desired result. Moreover, the job of evaluating the contractor's progress is often difficult. Such a contract is frequently phased and often divided into stages of accomplishment, each of which must be completed and approved before the contractor may proceed to the next. Phasing makes it necessary to develop methods and controls, including reporting requirements for each phase of the contract and criteria for evaluation of the report submitted, that will provide, at the earliest possible time, appropriate data for making decisions relative to future phases. A phased contract may include stages of accomplishment such as research, development, and demonstration. Within each phase, there may be a number of tasks which should be included in the SOW. When phases of work can be identified, the SOW will provide for phasing and the request for proposals will require the submission of proposed costs by phases. The resultant contract will reflect costs by phases, require the contractor to identify incurred costs by phases, establish delivery schedules by [[Page 26]] phase, and require the written acceptance of each phase. The provisions of the Limitation of Cost clause shall apply to the estimated cost of each phase. Contractors shall not be allowed to incur costs for phases which are dependent upon successful completion of earlier phases until written acceptance of the prior work is obtained from the contracting officer. (d) Elements of the SOW. The elements of the SOW will vary with the objective, complexity, size, and nature of the acquisition. In general, it should cover the following matters as appropriate. (1) A general description of the required objectives and desired results. Initially, a broad, nontechnical statement of the nature of the work to be performed. This should summarize the actions to be performed by the contractor and the results that the Government expects. (2) Background information helpful to a clear understanding of the requirements and how they evolved. Include a brief historical summary as appropriate and the relationship to overall program objectives. (3) A detailed description of the technical requirements. A comprehensive description of the work to be performed to provide whatever details are necessary for prospective offerors to submit meaningful proposals. (4) Subordinate tasks or types of work. A listing of the various tasks or types of work (it may be desirable in some cases to indicate that this is not all-inclusive). The degree of task breakout is directly dependent on the size and complexity of the work to be performed and the logical groupings. A single cohesive task should not be broken out merely to conform to a format. Indicate whether the tasks are sequential or concurrent for offeror planning purposes. (5) Reference material. All reference material to be used in the conduct of the project that tells how the work is to be carried out must be identified. Applicability should be explained, and a statement made as to where the material can be obtained. (6) Level of effort. When a level of effort is required, the number and type of personnel required should be stated. If known, the type and degree of expertise should be specified. (7) Special requirements. (as applicable). An unusual or special contractual requirement, which would impact on contract performance, should be included as a separate section. (8) Deliverables reporting requirements. All deliverables and/or reports must be clearly and completely described.
