This document defines a process measurement framework that supports the assessment of process capability, in accordance with the requirements of ISO/IEC33003. The process measurement framework provides a schema that can be used to construct a process assessment model conformant with ISO/IEC33004 which can be used in the performance of assessment of process capability according to the requirements of ISO/IEC33002. In the context of this document and related standards, process capability is a process quality characteristic related to the ability of a process to consistently meet current or projected business goals.The process measurement framework defined in this document forms a structure which facilitates self-assessment, provides a basis for use in process improvement and process quality determination, is applicable across all application domains and sizes of organization, produces a set of process (capability) attribute ratings (process profile), and derives a process capability level. This document also includes as informative annexes a set of assessment indicators of process capability that can be used in the construction of a process assessment model using this process measurement framework, and guidance on the meaning of the process capability levels and the achievement of the process attributes.
