5、ognized systems engineering best practice is early development of operational concepts during system development and documentation of those operational concepts in one or more operational concept documents. Recognizing this best practice, U. S. Department of Defense (DoD) and NASA standard procedure

6、s have required that information relating to system operational concepts is prepared in support of the specification and development of systems. In the past, the DoD has published Data Item Descriptions (DIDs), and NASA has published Data Requirements Documents (DRDs), which describe the format and

7、content of the information to be provided. This AIAA Guide describes which types of information are most relevant, their purpose, and who should participate in the operational concept development effort. It also provides advice regarding effective procedures for generation of the information and how

8、 to document it. ANSI/AIAA G-043A-2012 (Revision of G-043-1992) ii Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria have been met by the standards developer. Consensus is established when, in the judgment of

9、the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted

10、effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not co

11、nforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in

12、the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the

13、American National Standards Institute require that action be taken to affirm, revise, or withdraw this standard no later than five years from the data of approval.

24、 Preparation of Operational Concept Documents (OCD) has been sponsored by the American Institute of Aeronautics and Astronautics (AIAA) as a part of its Standards Program. It is an update and extension of the original ANSI/AIAA Guide (ANSI/AIAA G-043-1992), incorporating new insights, knowledge, and

25、 experience that have been recognized since the Guides original publication. The original Guide was developed by the AIAA Software Systems Committee on Standards and formed a sound foundation for this updated version. This edition of the Guide has been prepared by the AIAA Systems Engineering Commit

26、tee on Standards, the AIAA Software Engineering Technical Committee, and the Requirements Working Group of the International Council on Systems Engineering. At the time that the original Guide was published, various government standards required the generation of operations concept information. The

27、U.S. Department of Defense (DoD) had developed Data Item Descriptions (DIDs), but little information was provided describing the manner in which an Operational Concept Document should be used in support of a system development. No guidelines were provided regarding which information was most useful,

28、 how to develop that information, which developer and customer personnel should participate, or how to document it. Subsequent to the publication of the original Guide, the DoD embarked on a substantial acquisition reform activity, which resulted in the cancellation of many standards that had guided

29、 the development of systems and software in favor of comparable commercial standards. In the same time period, guides to the preparation of Operational Concept Documents were published by the Institute of Electrical and Electronic Engineers (IEEE 1362) and by ISO (ISO 14711:2002 (E). Lastly, many ad

30、vances have been made in the last decade in methods used in systems and software development, not the least of which has been the expansion of object orientation and the development of the Unified Modeling Language (UML) and the Systems Modeling Language (SysML). The original Guide, ANSI/AIAA G-043-

31、1992, was subject to review and revision in 1997. At approximately that time, members of the International Council on Systems Engineering Requirements Working Group (INCOSE RWG) had recognized a need for such a Guide and had begun work on their own document. After discussion between both organizatio

32、ns, the INCOSE RWG and the AIAA Systems Engineering Committee on Standards (SE CoS) decided to work jointly on the revision of the ANSI Guide. In addition, the INCOSE Net-Centric Operations (NCO) Working Group has worked jointly with the AIAA SETC in reviewing the G-043 document. The NCO Working Gro

33、up has concurred with the contents. Although the review and revision process was begun in 1997, it was not completed until 2011. The current Guide for the Preparation of Operational Concept Documents, in addition to including new information, has been broadened to encompass the development of all sy

34、stem types, including software-intensive systems, and to reflect technological advances of the last decade. Development of the current Guide has benefited from the cooperative effort between the AIAA and INCOSE by providing a broad systems-level viewpoint and inclusion of international knowledge, in

35、formation, and experience. This publication is a Guide and contains no normative material. It is informative only.

The AIAA Standards Procedures provide that all approved Standards, Recommended Practices, and Guides are ad

41、visory only. Their use by anyone engaged in industry or trade is entirely voluntary. There is no agreement to adhere to any AIAA standards publication and no commitment to conform to or be guided by a standards report. In formulating, revising, and approving standards publications, the Committees on

Prospective users of the publications are responsible for protecting themselves against liability for infringement of patents or copyrights, or both. ANSI/AIAA G-043A-2012 (Revision of G-043-1992) 1 1 Introduction 1.1 Purpo

43、se The purpose of this Guide is twofold. First, the Guide describes a time-tested process for operational concept development. Second, it is intended to recommend how to compile the information developed during operational concept development into one or more Operational Concept Documents (OCDs) enc

44、ompassing the full range of the product lifecycle (Haskins, 2010): concept, development, production, utilization, support, and retirement stages. 1.2 System The Operational Concept is prepared initially to support the concept and development stages of the system life cycle. The Operational Concept i

45、s then maintained throughout the Program to support the production, utilization, support, and retirement stages of the system life cycle. As the concept of “system” is central to the Operational Concept and its preparation and maintenance, for the purposes of this Guide, a system is defined as: A co

46、mbination of interacting elements organized to achieve one or more stated purposes. A system may be considered as a product or as the services it provides. In practice, the interpretation of its meaning is frequently clarified by the use of an associative noun (e.g., aircraft system). Alternatively,

47、 the word “system” may be substituted simply by a context-dependent synonym (e.g., aircraft), though this may then obscure the system principles perspective after ISO, 2008. Early in the system development activity, a system is conceptual in nature. As the development effort continues, the system be

48、comes realized in hardware, software, materials, personnel, facilities, and processes. A system may consist of several levels where each element at each lower level may by this definition itself be considered a system (i.e., a subsystem of a large system may itself possess all of the attributes of a

49、 system). 1.3 Operational Concept Document Versus Concept of Operations Document The terms “operational concept” and “concept of operations,” and the terms “operational concept document” and “concept of operations document,” are often used interchangeably in system development. Although there are similarities between the two terms in each set, there are also significant differences. It is important to understand the term “concept of operations” and “operational concept” before trying to understand the terms describing the documents. For the purposes of this Guide
