ISO/IEC 33063:2015 -定义符合ISO/IEC 33004要求的过程评估模型，并支持使用ISO/IEC 33020中定义的过程测量框架进行过程能力评估。过程评估模型为解释ISO/IEC/IEEE 29119-2中定义的过程目的和结果以及ISO/IEC 33020中定义的过程属性提供了指导指标，以及 -举例说明评估指标的定义、选择和使用。 过程评估模型包括一组过程性能和过程能力的指标。这些指标用作收集客观证据的基础，使评估员能够根据ISO/IEC 33002的要求分配评级。本国际标准中包含的一组指标并非全部指标- 包含性条款也不打算全部适用。应选择适合评估背景和范围的子集。 本国际标准中的过程评估模型针对希望选择模型和相关文件化过程方法进行评估（用于能力确定或过程改进）的评估发起人和合格评估人。 任何满足ISO/IEC 33004中有关过程评估模型的要求的软件测试过程评估模型均可用于评估。可能需要不同的模型和方法来满足不同的业务和测试需求。本评估模型作为满足ISO/IEC 33004中所有要求的模型的范例提供。

ISO/IEC 33063:2015 - defines a process assessment model that meets the requirements of ISO/IEC 33004 and that supports the performance of an assessment of process capability using the process measurement framework defined in ISO/IEC 33020. The process assessment model provides indicators for guidance on the interpretation of the process purposes and outcomes as defined in ISO/IEC/IEEE 29119 2 and the process attributes as defined in ISO/IEC 33020, and - provides guidance, by example, on the definition, selection, and use of assessment indicators. A process assessment model comprises a set of indicators of process performance and process capability. The indicators are used as a basis for collecting the objective evidence that enables an assessor to assign ratings, following the requirements of ISO/IEC 33002. The set of indicators included in this International Standard is not intended to be an all-inclusive set nor is it intended to be applicable in its entirety. Subsets that are appropriate to the context and scope of the assessment should be selected. The process assessment model in this International Standard is directed at assessment sponsors and competent assessors who wish to select a model and associated documented process method for assessment (for either capability determination or process improvement). Any process assessment model for software testing meeting the requirements defined in ISO/IEC 33004 concerning models for process assessment may be used for assessment. Different models and methods might be needed to address differing business and testing needs. This assessment model is provided as an exemplar of a model meeting all the requirements expressed in ISO/IEC 33004.
