本标准的目的是支持系统工程能力的发展和改进。本标准的范围包括所有与系统工程相关的活动。系统工程是一种跨学科的方法和手段，能够实现成功的系统。在这种情况下，系统工程并不局限于eigher系统工程组织或系统工程师所做的工作。相反，它是许多人、过程和组织的互动，从而完成所需的活动。 本标准旨在全面涵盖EIA-632系统工程过程，并与IEEE 1220-1994系统工程过程应用和管理的IEEE试用标准保持一致。原EIA/IS 731.1

The purpose of the Standard is to support the development and improvement of systems engineering capability.The scope of this Standard includes all activities that associate with or enable systems engineering. Systems engineering is an inter-disciplinary approach and means to enable the realization of successful systems. In this context, systems engineering is not limited to what eigher Systems Engineering organization or Systems Engineers do. Rather it is the interaction of many people, processes, and organizations resulting in the accomplishment of the required activities.This Standard is intended to provide complete coverage of EIA-632, Processes Engineering a System, and be consistent with both it and IEEE 1220-1994, IEEE Trial-Use Standard for Application and Management of the Systems Engineering Process.Formerly EIA/IS 731.1
