ISO/IEC 5259-3:2024

Overview

ISO/IEC 5259-3:2024 defines requirements and provides guidance for establishing, implementing, maintaining and continually improving the quality of data used for analytics and machine learning (ML). It sets out a generic, organization‑agnostic framework for a data quality management process, including a reference life cycle and methods that organizations can tailor. The standard specifically does not prescribe detailed processes, methods or numeric metrics - instead it requires and guides the design of a quality management approach suitable to each organization’s context.

Key topics and requirements

• Data quality management objectives: establish a process to ensure data is fit for analytics and ML use and continually improved.
• Organizational aspects: foster a data quality culture; define roles, responsibilities and competence management.
• Management system integration: align data quality activities with existing management systems and resources.
• Documentation & auditing: require documentation, audits, assessments, confirmation reviews and measurable work products.
• Life‑cycle coverage: specify requirements across data life‑cycle stages including:
  • Data motivation and conceptualization
  • Data specification
  • Data planning
  • Data acquisition
  • Data preprocessing
  • Data augmentation
  • Data provisioning
  • Data decommissioning
• Horizontal processes: verification & validation, configuration management, change management, and risk management for data quality.
• Supply chain & tooling: guidance for managing data quality across supplier relationships and for the management of data processing tools and dependencies.
• Project‑specific management: tailoring, planning, coordination, data quality justification, decommissioning and project work products.

Practical applications

• Build or improve an organizational data quality management program for ML and analytics projects.
• Design data governance controls that ensure data fitness for model training, evaluation and deployment.
• Integrate data quality requirements into project plans, supplier contracts and tooling procurement.
• Structure audits, verification/validation activities and documentation to support reproducibility, compliance and risk mitigation.
• Tailor the reference life cycle to specific projects (e.g., model development, data pipelines, labeling efforts) without inventing fixed metrics.

Who should use this standard

• Data governance leaders, Chief Data Officers (CDOs) and CIOs
• Data engineers, ML engineers and data scientists
• Quality assurance, compliance and risk management teams
• Procurement and supply‑chain managers working with data suppliers
• Tooling and platform architects responsible for data pipelines and processing tools

Related standards

• Other parts of the ISO/IEC 5259 series and complementary ISO/IEC AI and data management standards (consult the ISO catalogue for specific titles). These provide complementary guidance on AI systems, ethics and technical controls.
