Full title and description

Information technology — Process assessment — Process measurement framework for assessment of process capability (ISO/IEC 33020:2019). This International Standard defines a process measurement framework (a schema and measurement constructs) that supports assessment of process capability and the construction of process assessment models used to derive process capability levels and process attribute ratings.

Abstract

ISO/IEC 33020:2019 specifies a process measurement framework that supports the assessment of process capability in accordance with ISO/IEC 33003. The framework is intended to be used when constructing process assessment models conformant with ISO/IEC 33004 and applied in assessments performed under ISO/IEC 33002. The document includes informative annexes with example assessment indicators and guidance on interpreting capability levels and process attributes. The framework is applicable across application domains and organization sizes and is intended to support self-assessment, process improvement and process quality determination.

Scope

Defines a process measurement framework for assessing process capability that: provides a schema to build process assessment models (to be used with ISO/IEC 33004), supports deriving capability attribute ratings and capability levels, facilitates self-assessment, underpins process improvement and quality determination, and is applicable across domains and organization sizes. The framework is intended for use when performing assessments according to ISO/IEC 33002 and when meeting requirements of ISO/IEC 33003. Informative annexes provide example assessment indicators and explanatory guidance.

Key topics and requirements

• Definition of a process measurement framework to evaluate process capability.
• Schema and measurement constructs to produce process attribute ratings (process profile).
• Rules for deriving process capability levels from attribute ratings.
• Conformance with ISO/IEC 33003 (requirements for measurement frameworks) and alignment with ISO/IEC 33004 (process assessment models) and ISO/IEC 33002 (assessment performance requirements).
• Applicability across application domains and organization sizes; supports self-assessment and external assessment.
• Informative annexes offering candidate assessment indicators and guidance on interpreting capability levels and attributes.

Typical use and users

Used by process assessors, quality managers, internal/external auditors, process improvement consultants, and organizations seeking consistent, repeatable measurement of process capability. Commonly applied in software and systems engineering, IT service management, and other domains where process performance and capability need to be measured, benchmarked or improved.

Related standards

FAQ

Q: What is this standard?

A: ISO/IEC 33020:2019 is an international standard that defines a measurement framework used to assess the capability of processes — providing the schema and constructs for creating assessment models and deriving capability levels.

Q: What does it cover?

A: It covers the structure and measurement constructs needed to evaluate process capability, how to generate process attribute ratings (a process profile), and how to derive process capability levels; it also includes informative annexes with example assessment indicators and guidance on interpretation.

Q: Who typically uses it?

A: Process assessors, quality and process improvement professionals, auditors, consultants, and organizations in software/system engineering and IT service domains who need standardized, repeatable capability assessments.

Q: Is it current or superseded?

A: Edition 2 (2019) is the current published version; it superseded the 2015 edition. As an ISO standard it is subject to periodic review (typically every five years) and its status is maintained by ISO/IEC JTC 1/SC 7.

Q: Is it part of a series?

A: Yes — ISO/IEC 33020 is part of the ISO/IEC 33000 family (process assessment), which includes standards for concepts/terminology, assessment processes, measurement frameworks, assessment models and guidance documents.
