软件工程.过程评估.第2部分:执行评估

[中文适用范围]： ISO/IEC 15504 的这一部分涉及过程评估以及过程评估在改进和能力确定中的应用。 它定义了执行评估的最低要求，以确保评估结果客观、公正、一致、可重复并代表评估过程。 当评估范围相似时，可以比较一致过程评估的结果。 有关此问题的指导，请参阅 ISO/IEC 15504-4。 ISO/IEC 15504 本部分定义的过程评估要求形成了一个结构： a) 促进自我评估； b) 为过程改进和能力确定提供基础； c) 考虑实施评估过程的背景； d) 产生过程评级； e) 强调过程实现其目的的能力； f) 适用于所有应用领域和组织规模； g) 可以提供组织之间的客观基准。 注：版权发布：ISO/IEC 15504 这部分的用户可以自由复制相关材料，作为任何过程评估模型的一部分，或作为任何符合本国际标准的证明的一部分，以便将其用于其预期目的。 [外文原描述]： 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. The requirements for process assessment defined in ISO/IEC 15504-2:2003 form a structure which: facilitates self-assessment;provides a basis for use in process improvement and capability determination;takes into account the context in which the assessed process is implemented;produces a process rating;addresses the ability of the process to achieve its purpose;is applicable across all application domains and sizes of organization; andmay provide an objective benchmark between organizations. The minimum set of requirements defined in ISO/IEC 15504-2:2003 ensures that assessment results are objective, impartial, consistent, repeatable and representative of the assessed processes. Results of conformant process assessments may be compared when the scopes of the assessments are considered to be similar; for guidance on this matter, refer to ISO/IEC 15504-4.
