5 concepts5.1General
The ISO/IEC 330xx family of International Standards establishes a framework for performing andapplying process assessment.The framework can be applied to address the assessment of many processquality characteristics.
The family of Standards presents a process viewpoint of process assessment, providing a clear set ofrequirements for the process assessment process,and the resources required to implement it effectively.The ISO/IEC 330xx family of standards provides a structured approach for the assessment of processesfor the following purposes:
by or on behalf of an organization with the objective of understanding the state of its own processesfor process improvement;
by or on behalf of an organization with the objective of determining the suitability of its ownprocesses for a particular requirement or category of requirements;
by or on behalf of one organization with the objective of determining the suitability of anotherorganization’s processes for a particular contract or category of contracts.
The framework for process assessment:
一 facilitates self-assessment;
-provides a basis for improving process performance and mitigating risk;
produces a rating of the achievement of the relevant process quality characteristic; provides an objective benchmark between organizations;
is applicable across all application domains and sizes of organization.5.2 Concepts of “process”
A process is a set of elements (tasks, activities, etc) that operate together in a coordinated manner toachieve a purpose. In general, there are multiple ways of identifying and organising the “elements ofa process; there is no “one way” to achieve the purpose.In order to achieve an objective evaluation ofthe extent to which a process achieves a specified process quality characteristic, it is first necessary toestablish a generic definition of the process,as an entity that can be implemented in different contexts.Such a generic definition can be achieved by focussing on the Purpose of the process.The achievement ofthe purpose is demonstrated through the establishment of observable results or OutcomesL16].
This approach enables the achievement of a specific process quality characteristic to be evaluated byfocussing on the achievement of the process outcomes, and exploring (through review of objectiveevidence) the extent to which the specified process quality characteristic is achieved.

5.3.1Measuring process quality characteristics
ISO/IEC 33003 provides the requirements for defining process measurement frameworks of processattributes for process quality characteristics such as process capability, efficiency， effectiveness,security, integrity and sustainability.
In general, a process measurement framework describes process attributes related to processes thatprovide a coherent and consistent framework for evaluating the extent of achievement of the processquality characteristic that is the subject of the framework. The process measurement frameworkmay define a series of process quality levels,establishing an ordinal scale for expressing the extent ofachievement of the process quality characteristic.
5.3.2 Process reference models
An assessment addresses a selected scope of processes implemented in a specific domain.The resultsof assessment will be affected by the domain of implementation, as processes with similar purpose indifferent domains may have different results. A set of processes can be defined that address functionsin a domain of interest; the set of processes may address not only the core functions of organizationsoperating in the domain, but also processes concerned with management or support functions, or withthe provision of organizational or enterprise infrastructure[2.9.10].
A coherent set of processes for a specified domain can be assembled to provide a process referencemodel.A process reference model contains:
a) a declaration of the domain of the process reference model;
b) a description of the processes within the scope of the process reference model;
c)a description of the relationship between the process reference model and its intended context of
use; and
d) a description of the relationship between the processes defined within the process reference model.The requirements for a process reference model are contained in ISO/IEC 33004.BS ISO-IEC 33001 pdf download.
