ISO/IEC/IEEE 14764:2022本文件根据ISO/IEC/IEEE 12207:2017，6.4.13中定义的维护过程及其活动和任务，提供软件维护指南。此外，本文件更详细地描述了维护过程，并确定了各种维护类型的定义。这包括使用相同维护资源对多个软件产品进行维护。除非另有说明，本文件中的“维护”指软件维护
本文件未涉及软件的操作以及通常由软件操作人员执行的操作功能，例如备份、恢复、系统管理。 然而，它确实包括ISO/IEC/IEEE 12207:2017，6.4.14中定义的相关处理过程
本文件主要针对包含软件的系统的经理、维护组织、质量经理、用户和收单机构
本文档中讨论的许多活动和任务同样适用于维护服务以及维护软件产品。例如，在COTS密集型系统中，执行维护服务以维持产品的运行
虽然本文档的范围是软件维护，但硬件和硬件成本是维护的重要考虑因素。

ISO/IEC/IEEE 14764:2022 This document provides guidance for the maintenance of software, based on the maintenance process and its activities and tasks defined in ISO/IEC/IEEE 12207:2017, 6.4.13. Moreover, this document describes the maintenance process in greater detail and establishes definitions for the various types of maintenance. This includes maintenance for multiple software products with the same maintenance resources. “Maintenance” in this document means software maintenance unless otherwise stated.
The document does not address the operation of software and the operational functions, e.g. backup, recovery, system administration, which are normally performed by those who operate the software. However, it does include the related disposal process defined in ISO/IEC/IEEE 12207:2017, 6.4.14.
This document is written primarily for managers, maintenance organizations, quality managers, users and acquirers of systems containing software.
Many of the activities and tasks discussed in this document apply equally to maintenance services, as well as to maintained software products. For example, in a COTS intensive system, maintenance services are performed to sustain the product in operations.
While the scope of this document is software maintenance, hardware and hardware costs are important considerations for maintenance.
