Overview
ISO/IEC TS 33062:2025 is a Technical Specification from ISO/IEC that defines a process assessment model for quantitative processes. It is intended to be used when performing process assessments in accordance with ISO/IEC 33002 and to support higher levels of process capability defined in ISO/IEC 33020. The document provides a two‑dimensional model combining a process dimension (defined processes, purposes, outcomes, base practices and information items) and a quality dimension (process attributes and process quality indicators within a process measurement framework).
Key topics and requirements
- Two‑dimensional assessment model:
- Process dimension: lists quantitative processes (e.g., QNT.1 Quantitative performance management), their purpose statements, expected outcomes, base practices (BPs), and key information items (process inputs/outputs).
- Quality dimension: describes the process measurement framework (process attributes) used to judge quality and capability.
- Assessment indicators:
- Process performance indicators: base practice (BP), process input (PI), process output (PO).
- Process quality indicators: evidence types mapped to process attributes (including the mandatory process performance attribute).
- Conformance: the model is developed to meet the requirements of ISO/IEC 33004 (requirements for process reference, assessment and maturity models) and to be used with ISO/IEC 33002 assessment processes.
- Practical guidance: identifies that subsets of indicators should be selected according to assessment context and that assessor judgment and a documented assessment process are required.
- Supporting material: Annex A lists process outputs and information item descriptions for use as objective evidence.
Applications and users
Who will use ISO/IEC TS 33062:2025:
- Process assessors and lead assessors performing ISO/IEC 33002 assessments.
- Quality assurance, process improvement and measurement teams establishing quantitative process controls.
- Software and systems engineering organizations seeking to raise process capability using quantitative performance management and other quantitative processes.
- Consultants and tool vendors implementing assessment tooling or templates that use the model’s indicators and outputs.
Practical uses:
- Designing measurement programs and KPIs that align with process capability goals.
- Structuring evidence collection for capability assessments (selecting relevant BPs, PI/PO).
- Integrating with improvement programs to move organizations to higher ISO/IEC 33020 capability levels.
