本文件解释了定义流程时需要考虑的事项。本文件通过确定制定过程的要素和规则，给出了描述过程的要求和建议
本文档还介绍了流程视图的使用
本文件解释了当按照本文件描述过程时，如何定义过程的一致性
本文档不描述如何将流程组合或聚合为更大的框架或生命周期模型。该文件也不包括如何评估或评估过程的性能，或过程的输出（产品）。
注:软件和系统工程过程描述中的两个著名国际标准是ISO/IEC/IEEE 12207和ISO/IEC/IEEE 15288。这两个标准有非常相似的过程模型。ISO/IEC/IEEE 15289中给出了与其过程定义相关的信息项。其他国际标准通过详细阐述过程要素并对过程的执行提出具体要求，进一步描述了单一生命周期过程
本文件适用于与系统和软件工程过程相关的任何一方、组织或标准中描述各种过程定义的过程。

This document provides an explanation of considerations involved in defining a process. This document gives requirements and recommendations for the description of processes by identifying elements and rules for their formulation.
This document also describes the use of process views.
This document explains how conformance to a process can be defined, when the process is described in accordance with this document.
This document does not describe how processes are composed or otherwise aggregated into larger frameworks or life cycle models. Nor does the document cover how to assess or evaluate the performance of a process, or the output (products) of a process.
NOTE Two prominent International Standards in process description for software and system engineering are ISO/IEC/IEEE 12207 and ISO/IEC/IEEE 15288. These two standards have very similar process models. The information items associated with their process definitions are given in ISO/IEC/IEEE 15289. Other International Standards provide further characterization of a single life cycle process by elaborating the process elements and levying specific requirements on the execution of the process.
This document is applicable when processes are described for various process definitions in any party, organization or standard relating to systems and software engineering processes.
