Introduction
Digital data delivers value by enhancing all aspects of organizational performance, including:
— operational effectiveness and efficiency;
— safety;
— reputation with customers and the wider public;
— compliance with statutory regulations;
— consumer costs, revenues and stock prices.
The influence on performance originates from data being the formalized representation of information.
This information enables organizations to make reliable decisions. This decision making can be
performed by human beings directly and also by automated data processing including artificial
intelligence systems.
Through widespread adoption of digital computing and associated communication technologies,
organizations become dependent on digital data. This dependency amplifies the negative consequences
of the lack of quality in this data. These consequences are the decrease of organizational performance.
The biggest impact of digital data comes from two key factors:
— the data having a structure that reflects the nature of the subject matter;
— the data also being computer processable (machine readable) rather than just being for a person to
read and understand.
ISO 9000 explains that quality is not an abstract concept of absolute perfection. Quality is actually the
conformance of characteristics to requirements and, thus, any item of data can be of high quality for
one use but not for another use that has differing requirements.
EXAMPLE 1 When storing start times for meetings, a calendar application requires less precision than a
control system would for storing the times at which to activate a propulsion unit during a spaceflight.
The nature of digital data is fundamental to establishing requirements that are relevant to the specific
decisions that are made by each organization.
EXAMPLE 2 ISO/TS 8000-1 identifies that data has syntactic (format), semantic (meaning) and pragmatic
(usefulness) characteristics.
To support the delivery of high-quality data, the ISO 8000 series addresses:
— data governance, data quality management and maturity assessment;
EXAMPLE 3 ISO 8000-61 specifies a process reference model for data quality management.
— creating and applying requirements for data and information;
EXAMPLE 4 ISO 8000-110 specifies how to exchange characteristic data that is master data.
— monitoring and measuring data and information quality;
EXAMPLE 5 ISO 8000-8 specifies approaches to measuring data and information quality.
— improving data and, consequently, information quality;
EXAMPLE 6 ISO/TS 8000-81 specifies an approach to data profiling, which identifies opportunities to
improve data quality.
— issues that are specific to the type of content in a data set.

ISO 8000-66:2021(E)

EXAMPLE 7 ISO/TS 8000-311 specifies how to address quality considerations for product shape data.
Data quality management covers all aspects of data processing, including creating, collecting, storing,
maintaining, transferring, exploiting and presenting data to deliver information.
Effective data quality management is systemic and systematic, requiring an understanding of the
root causes of data quality issues. This understanding is the basis for not just correcting existing
nonconformities but also implementing solutions that prevent future reoccurrence of those
nonconformities.
EXAMPLE 8 If a data set includes dates in multiple formats including “yyyy-mm-dd”, “mm-dd-yy” and “dd-mm-
yy”, then data cleansing can correct the consistency of the values. Such cleansing requires additional information,
however, to resolve ambiguous entries (such as, “04-05-20”) and cannot address any process issues and people
issues, including training, that have caused the inconsistency.
As a contribution to this overall capability of the ISO 8000 series, this document supports the application
of ISO 8000-62 to determine the process maturity of data quality management in manufacturing
organizations. This support is provided by specifying assessment indicators for data processing in
manufacturing operations management specified by IEC 62264-1.
Organizations can use this document on its own or in conjunction with other parts of the ISO 8000
series.
This document supports activities that affect:
— one or more information systems;
— data flows within the organization and with external organizations;
— any phase of the data life cycle.
By implementing parts of the ISO 8000 series, an organization achieves the following benefits:
— establishing reliable foundations for digital transformation;
— recognizing how data in digital form has become a fundamental asset class that organizations rely
on to deliver value;
— securing evidence-based trustworthiness of data and information for all stakeholders;
— creating portable data that protects against the loss of intellectual property and that is reusable
across the organization and applications;
— achieving traceability of data back to original sources;
— ensuring all stakeholders work with common understanding of explicit data requirements.
ISO/TS 8000-1 provides a detailed explanation of the structure and scope of the whole ISO 8000 series.
Annex A contains an identifier that unambiguously identifies this document in an open information
system.

Part 66:
Data quality management: Assessment indicators for data
processing in manufacturing operations
1 Scope
This document specifies assessment indicators to support the assessment of organizational process
maturity for data quality management in the context of manufacturing operations management as
specified by IEC 62264-1.
The following are within scope of this document:
— assessment indicators that are work products generated by data processing (as specified by
ISO 8000-61) and, thus, enable rating of process performance, a process attribute specified by
ISO/IEC 33020;
— the role played by each work product in the processes of manufacturing operations management;
— the connection of each work product to the outcomes of the processes of manufacturing operations
management.
The following are outside the scope of this document:
— assessment indicators for any of the other process attributes specified by ISO/IEC 33020;
— methods or procedures to measure process capability.

NOTE The term "product" appears in both ISO 8000-2 and IEC 62264-1 but with different definitions. Both
definitions provide, however, a useful and relevant explanation of the meaning of the term.
4 Process maturity assessment
Given the fundamental role of data in decision making, any type of organization can deliver significant
benefits through data quality management. This delivery is sustainable, however, only when the
organization understands and continually improves existing capability to perform data quality
management. This understanding is the primary outcome of process maturity assessment.
This document applies to process maturity assessment in the specific context of (see Figure 1):
— implementations of the data processing as specified by the process reference model for data quality
management in ISO 8000-61;
— implementations of the data processing as part of manufacturing operations management as
specified by the functional model in IEC 62264-1 and as identified by this document (see Clause 5).
In this context, the process maturity assessment shall:
— conform to ISO 8000-62;
— assess implementations of data processing that conforms to ISO 8000-61;
— perform process attribute rating of process performance using the work products specified by
Clause 7.
NOTE 1 Process performance is a process attribute specified by ISO/IEC 33020 (see Clause 6).
NOTE 2 These work products are assessment indicators that conform to the requirements of ISO/IEC 33004.
NOTE 3 The work products are information inputs to and outputs from individual processes of manufacturing
operations management.
This document harmonizes the different ways of describing processes in IEC 62264-1, ISO 8000-61 and
ISO/IEC 33063 (see Annex B).
5 Manufacturing operations management
5.1 Scope of manufacturing operations management
IEC 62264-1 specifies manufacturing operations management to cover the categories of:
— production operations management;
