Introduction
Digital data deliver 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;
— innovation;
— consumer costs, revenues and stock prices.
In addition, many organizations are now addressing these considerations with reference to the United
1)
Nations Sustainable Development Goals .
The influence on performance originates from data being the formalized representation of
2)
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 lack of quality in these 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;
EXAMPLE 1 A research scientist writes a report using a software application for word processing. This report
includes a table that uses a clear, logical layout to show results from an experiment. These results indicate how
material properties vary with temperature. The report is read by a designer, who uses the results to create a
product that works in a range of different operating temperatures.
— the data being computer processable (machine readable) rather than just being for a person to read
and understand.
EXAMPLE 2 A research scientist uses a database system to store the results of experiments on a material.
This system controls the format of different values in the data set. The system generates an output file of digital
data. This file is processed by a software application for engineering analysis. The application determines the
optimum geometry when using the material to make a product.
ISO 9000 explains that quality is not an abstract concept of absolute perfection. Quality is actually
the conformance of characteristics to requirements. This actuality means that any item of data can
be of high quality for one purpose but not for a different purpose. The quality is different because the
requirements are different between the two purposes.
EXAMPLE 3 Time data are processed by calendar applications and also by control systems for propulsion
units on spacecraft. These data include start times for meetings in a calendar application and activation times in
a control system. These start times require less precision than the activation times.
The nature of digital data is fundamental to establishing requirements that are relevant to the specific
decisions that are made by each organization.
EXAMPLE 4 ISO 8000-1 identifies that data have syntactic (format), semantic (meaning) and pragmatic
(usefulness) characteristics.
1) https://sdgs.un.org/goals
2) ISO 8000-2 defines information as “knowledge concerning objects, such as facts, events, things, processes, or
ideas, including concepts, that within a certain context has a particular meaning”.

To support the delivery of high-quality data, the ISO 8000 series addresses:
— data governance, data quality management and maturity assessment;
EXAMPLE 5 ISO 8000-61 specifies a process reference model for data quality management.
— creating and applying requirements for data and information;
EXAMPLE 6 ISO 8000-110 specifies how to exchange characteristic data that are master data.
— monitoring and measuring information and data quality;
EXAMPLE 7 ISO 8000-8 specifies approaches to measuring information and data quality.
— improving data and, consequently, information quality;
EXAMPLE 8 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.
EXAMPLE 9 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 for also implementing solutions that prevent future reoccurrence of those
nonconformities.
EXAMPLE 10 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”). The cleansing also 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 specifies a procedure
by which any organization can assess process maturity according to the specific priorities of the
organization. This procedure provides a capability to assess and improve data quality management
[11][12]3)
processes. The procedure makes use of the Test Process Improvement method .
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 to improve organizational performance, an organization
achieves the following benefits:
— objective validation of the foundations for digital transformation of the organization;
— a sustainable basis for data in digital form becoming a fundamental asset class the organization
relies on to deliver value;
— securing evidence-based trust from other parties (including supply chain partners and regulators)
about the repeatability and reliability of data and information processing in the organization;
3) Numbers in square brackets refer to entries in the Bibliography.

— portability of data with resulting protection against loss of intellectual property and reusability
across the organization and applications;
— effective and efficient interoperability between all parties in a supply chain to achieve traceability
of data back to original sources;
— readiness to acquire or supply services where the other party expects to work with common
understanding of explicit data requirements.
ISO 8000-1 provides a detailed explanation of the structure and scope of the whole ISO 8000 series.
4)
ISO 8000-2 specifies the single, common vocabulary for the ISO 8000 series. This vocabulary is ideal
reading material by which to understand the overall subject matter of data quality. ISO 8000-2 presents
the vocabulary structured by a series of topic areas (for example, terms relating to quality and terms
relating to data and information).
Annex A of this document contains an identifier that conforms to ISO/IEC 8824-1. The identifier
unambiguously identifies this document in an open information system.

Data quality —
Part 64:
Data quality management: Organizational process
maturity assessment: Application of the Test Process
Improvement method
1 Scope
This document specifies how to apply the Test Process Improvement method to the assessment of
organizational process maturity. This document refines the language in the method, which has an
original purpose of more than just data quality management. This document supports improving
data quality management when an organization uses the process reference model in ISO 8000-61 as
the foundation for specifying the measurement goals for the process measurement necessary when
performing maturity assessment.
The following are within scope of this document:
[11][12]
— the relationship between the Test Process Improvement method and the procedure for
assessing process maturity of data quality management as specified by ISO 8000-61;
— the role of process measurement in accordance with ISO 8000-63 when performing assessment of
process maturity;
— the outputs from the procedure.
The following are outside the scope of this document:
— the purpose, outcomes and activities of processes for data quality management;
— specific content for the scope of individual quality management areas, the maturity levels and the
maturity level targets;
— specific content for each inspection order including the frequency of inspection points;
— instructions on how to develop a process improvement strategy in response to the outputs of the
procedure.
This document can be used in conjunction with or independently of quality management systems
standards.

4 Process maturity assessment
This document specifies a procedure for assessing process maturity. This procedure builds on the
requirements for process measurement specified by ISO 8000-63. The procedure provides a flexible
approach to meet the requirements of an organization using the procedure. This flexibility is from the
organization being able to define quality management areas that depend on the factors identified by the
organization as being most relevant when seeking to improve process maturity.
EXAMPLE 1 ISO/IEC 33020 differs from this document by specifying a fixed set of process attributes for use in
maturity assessment.
EXAMPLE 2 An organization chooses to make each quality management area correspond to the responsibilities
of a single role within the organization.
Each quality management area covers one or more measurement goals that are the basis for process
measurement supporting the maturity assessment. The assessment enables an organization to drive
progressive improvement of process maturity but does not establish a general benchmark for use by
the organization to compare itself with other organizations.
EXAMPLE 3 Two organizations define different quality management areas and, therefore, are unable directly
to compare the results from assessing process maturity.
The procedure highlights those quality management areas that have yet to reach the required target
for overall process maturity to reach the next level. These quality management areas become the focus
for improvement.
The initial steps of the procedure set up the organization to be able to perform maturity assessment.
This set up shall include, in accordance with ISO 8000-63, creating an inspection plan for the process
measurement. The organization can then proceed to use the rest of the procedure to perform
assessments at appropriate frequencies to track the evolution of maturity.
EXAMPLE 4 An organization creates an inspection plan and then decides to assess process maturity every six
months.
To establish a basis for improving data quality management (see Figure 1), the process maturity
assessment shall:
— assess implementations of processes specified by ISO 8000-61;
— execute the procedure as specified by Clause 5.
