CAN CSA ISO/IEC TS 33072-18: Process Capability Assessment Model for Quality Management
A Comprehensive Guide to the Canadian Adoption of the ISO/IEC Technical Specification for Quality Process Assessment
CAN CSA ISO/IEC TS 33072-18 is the Canadian adoption of ISO/IEC TS 33072:2018, a Technical Specification that provides a process capability assessment model specifically tailored for quality management processes. It is part of the ISO/IEC 33000 family of standards for process assessment. This document defines a comprehensive framework for evaluating the capability of processes used to manage quality within an organization, enabling consistent, objective, and repeatable assessments aligned with quality management principles.
Scope and Purpose
The scope of CAN CSA ISO/IEC TS 33072-18 covers the definition of a process capability assessment model (PAM) for quality management. It is intended to be used in conjunction with ISO/IEC 33004 (which describes process assessment models) and ISO/IEC 33003 (which describes the requirements for process measurement). The standard includes a set of indicators that can be used to assess the capability of processes drawn from quality management systems, such as those based on ISO 9001, as well as other process-oriented quality frameworks.
The primary purpose of this Technical Specification is to provide a process measurement framework that can be used to evaluate how well an organization’s quality management processes achieve their intended outcomes. It helps identify strengths and weaknesses, supports process improvement, and can serve as a basis for process capability determination in supplier evaluations, audits, or internal assessments.
Tip: CAN CSA ISO/IEC TS 33072-18 is not a management system standard like ISO 9001. Instead, it provides a structured model to assess the capability of processes within any quality management system, making it a powerful tool for process improvement and benchmarking.
Technical Requirements and Assessment Framework
Process Reference Model (PRM)
The standard defines a Process Reference Model (PRM) that includes a set of quality management processes. These processes are derived from the quality management process categories found in ISO/IEC TS 33072 and are aligned with the process architecture of ISO 9001:2015. Each process has a defined purpose and outcomes that form the basis for assessment.
Capability Levels and Attributes
The assessment model uses the capability levels defined in ISO/IEC 33020, ranging from Level 0 (Incomplete) to Level 5 (Innovating). Each level from Level 1 to Level 5 includes one or more process attributes that measure specific aspects of process capability. The following table summarises the capability levels and their associated process attributes relevant to quality management.
| Capability Level | Process Attribute(s) | Description |
|---|---|---|
| Level 1: Performed | PA 1.1 Process Performance | The process achieves its defined outcomes. |
| Level 2: Managed | PA 2.1 Performance Management PA 2.2 Work Product Management | The process is planned, monitored, and adjusted; work products are appropriately managed. |
| Level 3: Established | PA 3.1 Process Definition PA 3.2 Process Deployment | A defined standard process is deployed, using appropriate resources. |
| Level 4: Predictable | PA 4.1 Process Measurement PA 4.2 Process Control | The process operates within defined limits using quantitative techniques. |
| Level 5: Innovating | PA 5.1 Process Innovation PA 5.2 Process Optimization | Continuous improvement and innovation are achieved through quantitative feedback and optimisation. |
Assessment Indicators
For each process attribute, the standard provides a set of assessment indicators: process outcomes, base practices, and work products. These indicators guide the assessor in evaluating the extent to which a process attribute has been achieved. The indicators are generic enough to apply across various quality management contexts, yet specific enough to yield consistent results between assessments.
Important Note: The indicators in CAN CSA ISO/IEC TS 33072-18 are examples and not exhaustive. Users may tailor them to their specific context as long as the underlying capability level definitions remain compliant with ISO/IEC 33020.
Implementation Highlights
Implementing an assessment using CAN CSA ISO/IEC TS 33072-18 requires careful preparation and an understanding of the quality management processes being assessed. The following recommendations can help ensure a successful implementation.
- Define the scope of assessment: Select the quality management processes that will be assessed, considering the organization’s objectives, customer requirements, and applicable standards.
- Train assessors: Assessors must be competent in the ISO/IEC 33000 series, the quality management domain, and the specific assessment model. Certification to ISO/IEC 15534 (now replaced by ISO/IEC 33000) or similar is recommended.
- Use documented evidence: Base the assessment on objective evidence from process documentation, records, interviews, and observations. Avoid relying solely on self-assessments without verification.
- Leverage the model for improvement: The process capability profiles generated by the assessment should be used to prioritise improvement activities, not just to obtain a maturity rating.
Success Story: Organizations that have adopted ISO/IEC TS 33072 for their quality management assessments have reported better alignment between process improvement efforts and business goals, as well as more credible results in supplier process capability evaluations.
Common Pitfall: Avoid treating the assessment model as a checklist. The real value comes from understanding the intent of each process attribute and interpreting the indicators in the context of the organization’s processes.
Compliance and Certification Considerations
CAN CSA ISO/IEC TS 33072-18 is a Technical Specification and does not itself offer certification. However, it can be used within a conformity assessment scheme for process capability determination. For example, a third-party certification body might use this model to evaluate the capability of a supplier’s quality management processes as part of a supplier qualification program.
Compliance with the standard means performing assessments that conform to the model’s requirements and using the defined indicators. While there is no formal certification to CAN CSA ISO/IEC TS 33072-18, organizations can claim conformity if their assessment process meets the requirements of ISO/IEC 33001 (the framework for process assessment) and uses the model defined in this Technical Specification.
When implementing assessments for compliance purposes, it is essential to keep the assessment scope, process definitions, and evidence records consistent with the standard’s provisions. The Canadian adoption (CAN CSA) implies that the standard is identical to the international original, so compliance with the Canadian version ensures compliance with the international ISO/IEC TS 33072:2018.
FAQs
Q: What is the difference between CAN CSA ISO/IEC TS 33072-18 and ISO 9001?
A: ISO 9001 specifies requirements for a quality management system, while CAN CSA ISO/IEC TS 33072-18 provides a model to assess the capability of processes within such a system. They are complementary: ISO 9001 defines “what” to do, and the technical specification provides “how” to measure process capability.

Q: How does this standard relate to process maturity models like CMMI?
A: While both address process capability, the ISO/IEC 33000 series (including TS 33072) is an international standard framework that is vendor-neutral and can be applied to any domain. CMMI is a specific model that covers broader organizational maturity. TS 33072 focuses specifically on quality management processes and uses the capability level scheme from ISO/IEC 33020.
