9、 of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of TechAmerica from manufacturing or selling products not conform

10、ing to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TechAmerica members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TechAmerica in

11、 accordance with the American National Standards Institute (ANSI) patent policy. By such action, TechAmerica does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This TechAmerica Standard is considered to have

12、International Standardization implications, but the ISO/IEC activity has not progressed to the point where a valid comparison between the TechAmerica Standard and the ISO/IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable

13、 regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

45、g its products on time at an affordable price orcost. The focus, therefore, is on conceptualizing, creating, and realizing a system and the products thatmake up a system.This Standard was developed as a joint project of the Electronic Industries Alliance (EIA) and theInternational Council on Systems

46、 Engineering (INCOSE). This effort was chartered by the G-47 SystemsEngineering Committee of EIA and has been designated as Project PN-3537. This Standard has beenapproved by the EIA Engineering Department Executive Committee.Intended uses of this Standard includea) benchmarking by an enterprise aga

47、inst the requirements of this Standard for engineering a system,or portion thereof;b) preparing enterprise standards , policies, and procedures for engineering a system;c) developing lower-tier industry- or domain-specific process standards;d) developing process capability and assessment models ;e)

48、establishing terminology and concepts for better communications;f) developing training and education curricula;g) preparing plans for actual development of a product.Use is not limited to specific disciplines, industry sectors, or technology domains.To provide each enterprise with the greatest degre

49、e of flexibility for adapting to changing environmentswhile maintaining the integrity of adopted processes, this Standarda) limits the set of required processes to those directly related to the technical aspects ofengineering systems;b) defines representative tasks associated with each process;c) includes the relevant information f
