前言:信息技术部门的标准制定与国际标准制定相协调。通过CSA信息技术技术委员会（TCIT），加拿大人担任加拿大标准委员会（SCC）ISO/IEC信息技术联合技术委员会（ISO/IEC JTC1）的SCC镜像委员会（SMC），该委员会是加拿大的ISO成员机构，也是IEC加拿大国家委员会的发起人。此外，作为国际电信联盟（ITU）的成员，加拿大还参加了国际电报和电话咨询委员会（ITU-T）。为简洁起见，本标准通篇称为“CSA ISO/IEC/IEEE 42020”。出版时，ISO/IEC/IEEE 42020: 2019版仅适用于ISO和IEC的英文版本。CSA集团将在ISO和IEC发布法文版。本标准已由技术委员会正式批准，无需修改，并根据加拿大标准委员会对加拿大国家标准的要求制定。CSA集团已将其作为加拿大国家标准发布。范围:本文档为架构集合的治理和管理以及实体架构建立了一套流程描述。本文档还建立了一个支持过程描述，为这些其他架构过程提供支持。本文件中定义的过程适用于单个项目，也适用于执行多个项目的组织。 这些过程适用于架构或架构集合的整个生命周期。这些过程适用于管理和执行架构（architecture）实体生命周期中任何阶段的活动。附录D描述了本文件与其他标准之间的关系。

Preface:Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).For brevity, this Standard will be referred to as "CSA ISO/IEC/IEEE 42020" throughout.At the time of publication, ISO/IEC/IEEE 42020:2019 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:This document establishes a set of process descriptions for the governance and management of a collection of architectures and the architecting of entities. This document also establishes an enablement process description that provides support to these other architecture processes.The processes defined in this document are applicable for a single project, as well as for an organization performing multiple projects. These processes are applicable throughout the life of an architecture or a collection of architectures. These processes are applicable for managing and performing the activities within any stage in the life cycle of the architecture entities.Annex D describes the relationships between this document and other standards.
