本文件建立了系统和软件测量的通用流程和框架。它从工程角度定义了一个过程和相关术语。该过程可以应用于整个生命周期的项目和产品。度量过程可以在整个生命周期中应用，以帮助在系统或软件生命周期的所有阶段进行规划、管理、评估和决策。本文件还提供了支持定义、控制和改进组织或项目中使用的测量过程的活动。本文件不假设或规定测量的组织模型。例如，本文件的使用者根据当前的组织结构、文化和普遍的约束条件，决定组织内是否需要单独的衡量职能，以及衡量职能是否应整合到单个项目中或跨项目中。 本文件未规定一套具体的措施、方法、模型或技术。本文件的用户负责为项目选择一套措施，并定义这些措施在整个过程、产品和生命周期的其他要素中的应用。双方还负责选择和应用适用于本项目的适当方法、模型、工具和技术。本文件无意规定要制作的信息项的名称、格式、明确内容或记录媒体。本文件并不意味着文件应以某种方式打包或组合。这些决定由本文档的用户决定。ISO/IEC/IEEE 15289规定了生命周期过程信息项（文件）的内容。测量过程应与组织质量体系适当整合。 本文件并未明确涵盖内部审计和不合规报告的所有方面，因为它们被认为属于质量体系的范畴。本文件不与任何已制定的组织政策、标准或程序相冲突。但是，任何冲突都应得到解决，任何压倒一切的条件和情况都需要以书面形式引用，作为本文件适用的例外情况。

This document establishes a common process and framework for measurement of systems and software. It defines a process and associated terminology from an engineering viewpoint. The process can be applied to the project and products across the life cycle. The measurement process can be applied throughout the life cycle to aid the planning, managing, assessing, and decision-making in all stages of a system or software life cycle. This document also provides activities that support the definition, control and improvement of the measurement process used within an organization or a project.This document does not assume or prescribe an organizational model for measurement. The user of this document decides, for example, whether a separate measurement function is necessary within the organization and whether the measurement function should be integrated within individual projects or across projects, based on the current organizational structure, culture and prevailing constraints.This document does not prescribe a specific set of measures, method, model or technique. The users of this document are responsible for selecting a set of measures for the project and defining the application of those measures across the process, products, and other elements of the life cycle. The parties are also responsible for selecting and applying appropriate methods, models, tools and techniques suitable for the project.This document is not intended to prescribe the name, format, explicit content, or recording media of the information items to be produced. This document does not imply that documents be packaged or combined in some fashion. These decisions are left to the user of this document. ISO/IEC/IEEE 15289 addresses the content for life cycle process information items (documentation).The measurement process is supposed to be appropriately integrated with the organizational quality system. Not all aspects of internal audits and non-compliance reporting are covered explicitly in this document as they are assumed to be in the domain of the quality system.This document is not intended to conflict with any organizational policies, standards or procedures that are already in place. However, any conflict should be resolved and any overriding conditions and situations need to be cited in writing as exceptions to the application of this document.
