ISO/IEC/IEEE 15288:2023本文件建立了一个通用的过程描述框架，用于描述人类创建的系统的生命周期，从工程角度定义了一组过程和相关术语。这些过程可以应用于感兴趣的系统、它们的系统元件以及系统的系统。这些过程的选定集合可以应用于系统生命周期的各个阶段。这是通过利益相关者的参与来实现的，最终目标是实现客户满意度。 本文件定义了一套流程，以促进系统开发和系统生命周期中的收购方、供应商和其他利益相关者之间的信息交换。 本文档指定了支持组织或项目中使用的系统生命周期过程的定义、控制和改进的过程。组织和项目在获取和供应系统时可以使用这些流程。 本文件适用于同时担任收购方和供应商角色的组织。 本文件适用于系统的整个生命周期，包括系统的构思、开发、生产、使用、支持和退役，以及系统的采购和供应，无论是在组织内部还是外部进行。本文档的生命周期过程可以迭代和并发地应用于系统，也可以递归地应用于系统元素。 本文件适用于独一无二的系统、大规模生产的系统和定制的适应性系统。它也适用于完整的独立系统以及嵌入和集成到更大、更复杂和完整系统中的系统。本文档没有规定特定的系统生命周期模型、开发方法、方法、建模方法或技术。 本文档没有详细说明信息项的名称、格式、明确内容和记录介质。ISO/IEC/IEEE 15289规定了生命周期过程信息项（文档）的内容。

ISO/IEC/IEEE 15288:2023 This document establishes a common framework of process descriptions for describing the life cycle of systems created by humans, defining a set of processes and associated terminology from an engineering viewpoint. These processes can be applied to systems of interest, their system elements, and to systems of systems. Selected sets of these processes can be applied throughout the stages of a system's life cycle. This is accomplished through the involvement of stakeholders, with the ultimate goal of achieving customer satisfaction.
This document defines a set of processes to facilitate system development and information exchange among acquirers, suppliers, and other stakeholders in the life cycle of a system.
This document specifies processes that support the definition, control, and improvement of the system life cycle processes used within an organization or a project. Organizations and projects can use these processes when acquiring and supplying systems.
This document applies to organizations in their roles as both acquirers and suppliers.
This document applies to the full life cycle of systems, including conception, development, production, utilization, support and retirement of systems, and to the acquisition and supply of systems, whether performed internally or externally to an organization. The life cycle processes of this document can be applied iteratively and concurrently to a system and recursively to the system elements.
This document applies to one-of-a-kind systems, mass-produced systems, and customised, adaptable systems. It also applies to a complete stand-alone system and to systems that are embedded and integrated into larger more complex and complete systems.
This document does not prescribe a specific system life cycle model, development methodology, method, modelling approach or technique.
This document does not detail information items in terms of name, format, explicit content, and recording media. ISO/IEC/IEEE 15289 addresses the content for life cycle process information items (documentation).
