ISO 8000-66:2021

Overview

ISO 8000-66:2021 - "Data quality - Part 66: Data quality management: Assessment indicators for data processing in manufacturing operations" specifies assessment indicators to support organizational process maturity evaluation for data quality management in manufacturing. It focuses on assessment indicators that are work products produced by data processing (as defined in ISO 8000‑61), the role each work product plays in manufacturing operations management (per IEC 62264‑1), and how those work products connect to process outcomes. The standard does not define measurement methods for process capability or address other process attributes beyond process performance.

Key technical topics and requirements

• Assessment indicators as work products: Indicators are defined as the outputs of data processing that enable rating of process performance (aligned with ISO/IEC 33020 process attributes).
• Mapping to manufacturing processes: Links work products to specific manufacturing operations activities (e.g., production scheduling, production control, material and energy control, inventory control, quality assurance, maintenance management - see Clause 5).
• Process maturity assessment context: Intended for implementations that conform to the ISO 8000‑61 data quality process reference model and assessed according to ISO 8000‑62.
• Scope limitations: Excludes indicators for process attributes other than performance and excludes procedures for measuring process capability.

Practical applications

• Improve data governance and operational decision‑making by identifying which data products indicate process performance in manufacturing.
• Support digital transformation and integration projects by clarifying the role of data outputs (work products) in MES, ERP and control systems.
• Provide a structured basis for internal or external process maturity assessments focused on data quality management in manufacturing environments.
• Help prioritize data quality improvements that directly affect manufacturing outcomes such as throughput, quality assurance, maintenance effectiveness and inventory accuracy.

Who should use this standard

• Data quality managers and data governance teams in manufacturing organizations
• Manufacturing operations managers, production planners and process engineers
• IT/OT architects, MES/ERP integrators and system implementers
• Auditors and consultants conducting maturity assessments or advising on data quality management

Related standards

• ISO 8000‑2 (Vocabulary)
• ISO 8000‑61 (Data quality management: Process reference model)
• ISO 8000‑62 (Organizational process maturity assessment)
• IEC 62264‑1 (Enterprise‑control system integration - Models and terminology)
• ISO/IEC 33020 (Process assessment attributes)

By using ISO 8000‑66:2021 together with the referenced ISO 8000 and IEC standards, organizations can more precisely assess and improve the quality of manufacturing data that drives operational performance.
