Process Assessment

Process assessment software engineering standards are published by ISO/IEC. They include the ISO/IEC 33000 series, which covers concepts and terminology, requirements for performing process assessment, requirements for process measurement frameworks, requirements for process reference, assessment, and maturity models, and framework for assessment of process capability.


ISO/IEC 33001:2015

Information technology - Process assessment - Concepts and terminology

ISO/IEC 33001:2015 provides a repository for key terminology relating to process assessment. It gives overall information on the concepts of process assessment, the application of process assessment for evaluating the achievement of process quality characteristics, and the application of the results of process assessment to the conduct of process management. ISO/IEC 33001:2015 provides an introduction to the ISO/IEC 330xx family of standards for process assessment; it describes how the parts of the family of standards for process assessment fit together and provides guidance for their selection and use. It explains the requirements contained within the suite and their applicability to performing assessments.


ISO/IEC 33002:2015

Information technology - Process assessment - Requirements for performing process assessment

ISO/IEC 33002:2015 defines the minimum set of requirements for performing an assessment that will ensure assessment results are objective, consistent, repeatable, and representative of the assessed processes. The requirements defined in ISO/IEC 33002:2015 can be used by or on behalf of an organization to a) facilitate self-assessment, b) provide a basis for improving process performance and mitigating process-related risk, c) produce a rating of the achievement of the relevant process quality characteristic, and d) provide an objective benchmark between organizations. ISO/IEC 33002:2015 is applicable across all application domains and sizes of organization.


ISO/IEC 33003:2015

Information technology - Process assessment - Requirements for process measurement frameworks

ISO/IEC 33003:2015 sets out the requirements for process measurement frameworks for use in process assessment. The requirements defined in ISO/IEC 33003:2015 form a structure which a) establish the requirements for process measurement frameworks in the context of process assessment, b) establish the requirements for the validation of process measurement frameworks for use in process assessment, and c) establish requirements that are applicable to any process measurement frameworks to develop composite measures across domains. ISO/IEC 33003:2015 is applicable to the development of process measurement frameworks for any process quality characteristic across all application domains.


ISO/IEC 33004:2015

Information technology - Process assessment - Requirements for process reference, process assessment and maturity models

ISO/IEC 33004:2015 sets out the requirements for process reference models, process assessment models, and maturity models. The requirements defined in this International Standard form a structure which specifies a) the relationship between the classes of process model associated with the performance of process assessment, b) the relationship between process reference models and prescriptive/normative models of process performance, as constituted by, for example, the activities and tasks defined in ISO/IEC 12207 and ISO/IEC 15288, c) the integration of process reference models and process measurement frameworks to establish process assessment models, d) the use of common sets of assessment indicators of process performance and process quality in process assessment models, and e) the relationship between maturity models and process assessment models and the extent to which a maturity model can be constructed using elements from different process assessment models.


ISO/IEC 33020:2019

Information technology - Process assessment - Process measurement framework for assessment of process capability

This document defines a process measurement framework that supports the assessment of process capability, in accordance with the requirements of ISO/IEC 33003. The process measurement framework provides a schema that can be used to construct a process assessment model conformant with ISO/IEC 33004 which can be used in the performance of assessment of process capability according to the requirements of ISO/IEC 33002. 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 a) facilitates self-assessment, b) provides a basis for use in process improvement and process quality determination, c) is applicable across all application domains and sizes of organization, d) produces a set of process (capability) attribute ratings (process profile), and e) 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.
