信息技术.过程评定.第4部分:用于过程改进和过程容量测定的指南

[中文适用范围]： ISO/IEC 15504 的这一部分提供了有关如何在过程改进计划或过程能力确定中使用一致性过程评估的指南。 ISO/IEC 15504 的这一部分仅供参考。 尽管文本中的一些示例和表格基于 ISO/IEC 12207 的流程，但所提供的指南并未假定特定的组织结构、管理理念、生命周期模型或开发方法。 在流程改进的情况下，概念和原则适用于各种不同的业务目标、应用领域和组织规模，因此所有类型的组织都可以使用它们。 在过程能力确定的情况下，本指南适用于任何客户-供应商关系，以及任何希望确定其自身过程的过程能力的组织。 [外文原描述]： ISO/IEC 15504 provides a framework for the assessment of processes. This framework can be used by organizations involved in planning, managing, monitoring, controlling, and improving the acquisition, supply, development, operation, evolution and support of products and services. ISO/IEC 15504-4:2004 provides guidance on how to utilize a conformant process assessment within a process improvement programme or for process capability determination. Within a process improvement (PI) context, process assessment provides a means of characterizing an organizational unit in terms of the capability of selected processes. Analysis of the output of a conformant process assessment against an organizational unit's business goals identifies strengths, weaknesses and risks related to the processes. This, in turn, can help determine whether the processes are effective in achieving business goals, and provide the drivers for making improvements. Process capability determination (PCD) is concerned with analysing the output of one or more conformant process assessments to identify the strengths, weaknesses and risks involved in undertaking a specific project using the selected processes within a given organizational unit. A process capability determination can provide a fundamental input to supplier selection, in which case it is often termed a "supplier capability determination". ISO/IEC 15504-4:2004 describes the PI and PCD processes and how to deploy them, and provides guidance on utilizing process assessment,selecting Process Reference Model(s),setting target capability,defining the assessment input,inferring process-related risk from assessment output,steps of process improvement,steps of process capability determination,comparability of assessment output analysis.
