Overview
ISO/IEC TR 33023:2024 - Information technology - Process assessment - Application of ISO/IEC TS 33073 processes to the ISO/IEC 33020 process capability measurement scale - is a Technical Report that specifies how processes defined in ISO/IEC TS 33073 can be associated with the process attribute outcomes used by ISO/IEC 33020. Its intent is to demonstrate support for process capability levels 1 to 3 of the ISO/IEC 33020 measurement framework. Published as the first edition in 2024, this TR targets developers of assessment models, lead assessors and stakeholders who need traceable evidence that ISO/IEC 33020 requirements are met.
Key topics and requirements
- Mapping of model elements: Provides a formal mapping between ISO/IEC TS 33073 processes and ISO/IEC 33020 process attribute outcomes to validate capability levels 1–3.
- Information items as links: Uses defined information items and their characteristics to connect process outcomes to process attribute outcomes (Annex C lists these items).
- Generic and base practices alignment: Describes relationships between ISO/IEC 33020 generic practices and ISO/IEC TS 33073 base practices (Annex B).
- Detailed associations and validation: Annex A supplies extended, inspectable associations (process outcomes ↔ process attribute outcomes) to support assessment evidence and validation.
- Traceability considerations: Annex D discusses model traceability and mapping concerns, referencing ISO/IEC/IEEE 24774 guidance.
- Notable editorial points: Includes a renamed ORG-01 to “customer property management” and the addition of COM-12 (Knowledge Management) split into establish/maintain to support ISO/IEC 33020 PA 3.1/3.2 intent.
Practical applications and users
- Assessment model developers: Use the mappings to design process assessment models consistent with ISO/IEC 33020 capability levels 1–3.
- Lead assessors and audit teams: Use associations and information items to gather and validate objective evidence during process capability assessments.
- Quality, process and compliance managers: Plan improvements, prioritize process strengthening actions, and demonstrate conformance to a recognized process capability scale.
- Tool vendors & trainers: Implement assessment tooling and training materials aligned with the ISO/IEC 33020 measurement framework and TS 33073 processes.
