标准范围

ISO/IEC 15504-2:20 03定义了执行过程评估的要求，作为过程改进和能力确定的基础。过程评估基于包含过程维度和能力维度的二维模型。过程维度由外部过程参考模型提供，该模型定义了一组以过程目的和过程结果陈述为特征的过程。能力维度由一个测量框架组成，该框架包括六个过程能力级别及其相关的过程属性。评估输出由每个被评估过程的一组过程属性评级组成，称为过程概况，还可能包括该过程达到的能力水平。ISO/IEC 15504-2:20 03确定了过程能力的测量框架和要求:执行评估；过程参考模型；过程评估模型；验证过程评估的一致性。ISO/IEC 15504-2:20 03中定义的过程评估要求形成了一个结构:促进自我评估；提供用于过程改进和能力确定的基础；考虑实施被评估过程的背景；产生过程评级；解决流程实现其目的的能力；适用于所有应用领域和组织规模；并且可以在组织之间提供客观的基准。ISO/IEC 15504-2:20 03中定义的一组最低要求确保评估结果客观、公正、一致、可重复并代表被评估过程。当评估范围被认为相似时，可以比较符合性过程评估的结果；有关该事项的指导，请参考ISO/IEC 15504-4。

ISO/IEC 15504-2:2003 defines the requirements for performing process assessment as a basis for use in process improvement and capability determination.

Process assessment is based on a two dimensional model containing a process dimension and a capability dimension. The process dimension is provided by an external process reference model, which defines a set of processes characterized by statements of process purpose and process outcomes. The capability dimension consists of a measurement framework comprising six process capability levels and their associated process attributes.

The assessment output consists of a set of process attribute ratings for each process assessed, termed the process profile, and may also include the capability level achieved by that process.

ISO/IEC 15504-2:2003 identifies the measurement framework for process capability and the requirements for:

• performing an assessment;
• process reference models;
• process assessment models;
• verifying conformity of process assessment.
