系统和软件工程.软件生命周期过程

[中文适用范围]： 该国际标准为软件生命周期过程建立了一个通用框架，具有明确定义的术语，可供软件行业参考。 它包含在获取软件产品或服务期间以及在软件产品的供应、开发、操作、维护和处置期间应用的流程、活动和任务。 软件包括固件的软件部分。 本国际标准适用于系统和软件产品及服务的采购，软件产品和系统软件部分的供应、开发、操作、维护和处置，无论是在组织内部还是外部执行。 包括为软件产品和服务提供上下文所需的系统定义的那些方面。 该国际标准还提供了可用于定义、控制和改进软件生命周期过程的过程。 本国际标准的流程、活动和任务（无论是单独使用还是与 ISO/IEC 15288m 结合使用）也可以在包含软件的系统的采购过程中应用。 [外文原描述]： ISO/IEC 12207:2008 establishes a common framework for software life cycle processes, with well-defined terminology, that can be referenced by the software industry. It contains processes, activities, and tasks that are to be applied during the acquisition of a software product or service and during the supply, development, operation, maintenance and disposal of software products. Software includes the software portion of firmware. ISO/IEC 12207:2008 applies to the acquisition of systems and software products and services, to the supply, development, operation, maintenance, and disposal of software products and the software portion of a system, whether performed internally or externally to an organization. Those aspects of system definition needed to provide the context for software products and services are included. ISO/IEC 12207:2008 also provides a process that can be employed for defining, controlling, and improving software life cycle processes. The processes, activities and tasks of ISO/IEC 12207:2008 - either alone or in conjunction with ISO/IEC 15288 - may also be applied during the acquisition of a system that contains software.
