Introduction
This document can assist readers in relating the requirements specified in ISO/IEC 20000–1 to guidance
1)
in one of the most commonly used service management frameworks, ITIL . Organizations can refer
to this guidance as a cross-reference to help them plan and implement a service management system
(SMS).
ISO/IEC 20000–1 specifies requirements for a service management system. ISO/IEC 20000–1 can be
used in different ways, including:
a) as a source of requirements for organizations on the planning, design, transition, delivery and
improvement of services and service management capabilities;
b) to establish a consistent approach for an organization and all other parties involved in the service
lifecycle;
c) as a basis to assess, measure and report an organization’s service provision and service management
capabilities;
d) as a set of criteria for audit and assessment of an organization’s SMS, including service management
processes.
ISO/IEC 20000–1 specifies an integrated process approach where the organization establishes,
implements, maintains and continually improves a service management system (SMS). The services
can be delivered to internal or external customers or a combination of both. Other parts of the
ISO/IEC 20000 series provide supporting guidance.
ITIL is introduced in the ITIL® Foundation – ITIL 4 Edition publication as:
“ITIL has led the ITSM industry with guidance, training and certification (qualifications) programmes
for more than 30 years. ITIL 4 brings ITIL up to date by reshaping most of the established ITSM (IT
service management) practices in the wider context of customer experience, value streams, and digital
transformation, as well as embracing new ways of working, such as Lean, Agile and DevOps.”
“ITIL 4 provides the guidance organizations need to address new service management challenges and utilize
the potential of modern technology. It is designed to use a flexible, coordinated and integrated system for
the effective governance and management of IT-enabled services.”
AXELOS has agreed on the development of this document. ITIL, including the ITIL manuals, is owned by
AXELOS.
Organizations can implement and improve their SMS using the requirements specified in ISO/IEC 20000–
1, the guidance in the other parts of the ISO/IEC 20000 series and ITIL. Both the ISO/IEC 20000 series
and ITIL provide guidance to plan, design, transition, deliver and improve services that create value to
the business and its customers. An organization can adopt ITIL guidance to support the management
of their services in alignment with the requirements specified in ISO/IEC 20000–1. Other guidance can
also be used to support ISO/IEC 20000–1.

4 ISO/IEC 20000–1 and ITIL 4
4.1 Introduction to ISO/IEC 20000–1
ISO/IEC 20000-1 specifies requirements for establishing, implementing, maintaining and continually
improving a service management system (SMS). An SMS supports the management of the service
lifecycle, including the planning, design, transition, delivery and improvement of services, which
meet agreed requirements and deliver value for customers, users and the organization delivering the
services. The organization in the scope of the SMS can be a whole or part of a larger organization and
can also be known as the service provider.
ISO/IEC 20000-1 is intentionally independent of specific guidance. The organization can use a
combination of generally accepted frameworks (e.g. ITIL) and its own experience. Appropriate tools for
service management can be used to support the SMS.
All requirements specified in ISO/IEC 20000-1 are generic and are intended to be applicable to all
organizations, regardless of the organization’s type or size, or the nature of the services delivered.
While it can be used ‘regardless of the organization’s type or size, or the nature of the services
delivered’, ISO/IEC 20000-1 has its roots in IT. It is intended for service management of services using
technology and digital information. The examples given in this document illustrate a variety of uses of
ISO/IEC 20000-1.
Exclusion of any of the requirements in ISO/IEC 20000-1:2018, Clauses 4 to 10, is not acceptable when
the organization claims conformity to ISO/IEC 20000-1, irrespective of the nature of the organization.
The organization cannot demonstrate conformity to the requirements specified in ISO/IEC 20000-1 if
other parties are used to provide or operate all services, service components or processes within the
scope of the SMS.
ISO/IEC 20000-10 includes the concepts for an SMS, the vocabulary used for the ISO/IEC 20000 series,
a description of each part of the series and related standards. The vocabulary is split into subclause 3.1
for terms common to management system standards, subclause 3.2 for terms specific to service
management used in ISO/IEC 20000-1 and subclause 3.3 for terms used in the rest of the ISO/IEC 20000
series. Subclauses 3.1 and 3.2 are the same as in ISO/IEC 20000-1.
Guidance is available in other parts of the ISO/IEC 20000 series in the form of :
— ISO/IEC 20000-2 (Guidance on the application of service management systems),
— ISO/IEC 20000-3 (Guidance on scope definition and applicability of ISO/IEC 20000-1),
— ISO/IEC 20000-5 (Exemplar implementation plan for ISO/IEC 20000-1),
— ISO/IEC 20000-6 (Requirements for bodies providing audit and certification of service management
systems) and
— ISO/IEC 20000-7 (Guidance on the Integration and Correlation of ISO/IEC 20000-1:2018 to
ISO 9001:2015 and ISO/IEC 27001:2013).

4.2 Introduction to ITIL 4
4.2.1 General
ITIL 4 was published by AXELOS in 2019 as an evolution of previous versions. ITIL 4 has a new
architecture and scope. It aims to connect various approaches to the management of digital technology
into a holistic and comprehensive framework to address IT service management.
The key components of the ITIL 4 framework are the four dimensions model and the ITIL service value
system.
4.2.2 The four dimensions model
To support a holistic approach to service management, ITIL defines four dimensions that collectively
are critical to the effective and efficient delivery of value for customers and other stakeholders in the
form of products and services. The four dimensions are:
— Organizations and people: define the way an organization is managed, the roles and responsibilities
and authorities, and communication;
— Information and technology: define the information and knowledge necessary for the management
of services and the technologies required;
— Partners and suppliers: define an organization’s relationships with other organizations that are
involved in the services, including contracts and other agreements;
© ISO/IEC 2021 – All rights reserved 3

---------------------- Page: 8 ----------------------
ISO/IEC TS 20000-11:2021(E)

— Value streams and processes: define how the various parts of an organization work in an
integrated and coordinated way to enable value creation through the services.
The four dimensions represent perspectives which are relevant to the whole SVS, including the entirety
of the service value chain and all ITIL practices. The four dimensions are constrained or influenced
by external factors such as political, economic, social, technological, legal or environmental (PESTLE),
which are beyond the control of the service value system.
4.2.3 The ITIL service value system
The ITIL service value system (SVS) represents how the various components and activities of the
organization work together to facilitate value creation. ITIL calls this value co-creation, to indicate
that value is created together by the organization, its customers and other organizations in the service
relationship. The core components of the ITIL SVS, as shown in Figure 2, are:
— governance;
— continual improvement;
— the ITIL guiding principles;
— the ITIL service value chain;
— the ITIL practices.

4.2.4 Governance
Governance is the means by which an organization is directed and controlled. The role and position of
governance in the ITIL SVS will vary depending on how the SVS is applied in an organization.

4.2.5 Continual improvement
Continual improvement is a recurring organizational activity performed at all levels to ensure that an
organization’s performance continually meets stakeholders’ (interested parties’) expectations. ITIL 4
supports continual improvement with the ITIL continual improvement model which includes the steps
shown in Figure 3.

4.2.6 The ITIL guiding principles
The ITIL guiding principles are recommendations that can guide an organization in all circumstances,
regardless of changes in its goals, strategies, type of work or management structure. They are universal
and enduring and represent the core messages of ITIL and of service management, supporting successful
actions and good decisions of all types and at all levels. They can be used to guide organizations in
their work as they adopt a service management approach and adapt ITIL guidance to their own specific
needs and circumstances. The seven ITIL guiding principles are:
— Focus on value. Everything that the organization does needs to map, directly or indirectly, to value
for the stakeholders.
© ISO/IEC 2021 – All rights reserved 5

---------------------- Page: 10 ----------------------
ISO/IEC TS 20000-11:2021(E)

— Start where you are. Do not start from scratch and build something new without considering what
is already available to be leveraged.
— Progress iteratively with feedback. Do not attempt to do everything at once; organize the work
into smaller manageable segments for better results and ongoing improvement through feedback.
— Collaborate and promote visibility. Working together across boundaries produces results that
have greater acceptance, more relevance to objectives and increased likelihood of long-term success.
— Think and work holistically. No service, or element used to provide a service, stands alone. Taking
a holistic approach to service management includes establishing an understanding of how all the
parts of an organization work together in an integrated way.
— Keep it simple and practical. If a process, service, action or metric fails to provide value or produce
a useful outcome, eliminate it. Use the minimal number of steps to achieve the objective.
— Optimize and automate. Resources of all types, particularly human resources, should be used to
their best effect. Eliminate anything that is truly wasteful and use technology to achieve whatever
it is capable of. Human intervention should only happen where it really contributes value.
4.2.7 The ITIL service value chain
The central element of the SVS is the service value chain, an operating model which outlines the key
activities required to respond to demand and facilitate value realization through the creation and
management of products and services. The ITIL service value chain includes six value chain activities,
as shown in Figure 4:
— Plan: Ensure a shared understanding of the vision, current status and improvement direction of all
services in the organization;
— Improve: Ensure continual improvement of products, services and practices across all value chain
activities and the resources in the four dimensions of service management;
— Engage: Ensure transparency, continual engagement, good relationships and a good understanding
of stakeholder needs;
— Design and transition: Ensure that services continually meet stakeholder expectations for quality,
costs and time to market;
— Obtain/build: Ensure that service components are available when and where they are needed and
meet agreed specifications;
— Deliver and support: Ensure that services are delivered and supported to agreed specifications
and stakeholders’ expectations.

4.2.8 The ITIL practices
Practices are sets of organizational resources designed for performing work or accomplishing an
objective. They consider resources required across each of the four dimensions of service management
for a more holistic approach to achieve a successful outcome. These are distinct from processes, which
are sets of interrelated or interacting activities that transform inputs into outputs. Processes define the
sequence of activities and their dependencies and can be part of practices within the value stream and
processes dimension. The ITIL SVS includes 14 general management practices, 17 service management
practices and three technical management practices, as shown in Table 1.

4.2.9 Value streams
A value stream is a series of steps an organization undertakes to create and deliver products and
services to consumers. These steps can be seen as journeys through the six value chain activities for
specific scenarios or types of demand. They use resources of the service provider and the service
consumers to generate required outputs, such as resolving an incident or designing a new service.
4.3 Relationship between ISO/IEC 20000–1 and ITIL
ISO/IEC 20000–1 and ITIL are not based on each other, but they have features in common and there
are relationships between the two. There is a strong correlation between most of the ISO/IEC 20000-1
requirements and ITIL guidance. Refer to Annex B for detailed correlation.
Using ISO/IEC 20000–1 and ITIL together can support organizations intending to implement and derive
the benefits from service management. For organizations that wish to demonstrate conformity with
the requirements specified in ISO/IEC 20000–1, ITIL can be a starting point. Implementation teams can
take the basic principles and approaches suggested by ITIL and adapt the framework to their service
management objectives, organizational structure, existing roles and culture, ensuring that they meet
the requirements of ISO/IEC 20000-1. For example, ITIL is a source of guidance that can be used to meet
the requirements in ISO/IEC 20000-1:2018, Clause 8 and other clauses.
As ISO/IEC 20000-1 specifies the critical aspects of service management, it can be used as an approach
to navigate through the critical parts of service management frameworks such as ITIL. This can be
achieved by looking at the ISO/IEC 20000 requirements and guidance before examining the more
detailed guidance that can be found in the framework(s) of choice. This approach can therefore
help organizations to identify and establish a solid foundation for service management that can be
continually improved. Once the processes have been implemented, the organization can conduct a gap
analysis to see what improvements can be implemented.

Introduction
This document can assist readers in relating the requirements specified in ISO/IEC 20000–1 to guidance
1)
in one of the most commonly used service management frameworks, ITIL . Organizations can refer
to this guidance as a cross-reference to help them plan and implement a service management system
(SMS).
ISO/IEC 20000–1 specifies requirements for an information technology service management system.
ISO/IEC 20000–1 can be used in different ways, including:
a) as a source of requirements for organizations on the planning, design, transition, delivery and
improvement of services and service management capabilities;
b) to establish a consistent approach for an organization and all other parties involved in the service
lifecycle;
c) as a basis to assess, measure and report an organization’s service provision and service management
capabilities;
d) as a set of criteria for audit and assessment of an organization’s SMS, including service management
processes.
ISO/IEC 20000–1 specifies an integrated process approach when the organization establishes,
implements, maintains and continually improves a service management system (SMS). The services
can be delivered to internal or external customers or a combination of both. Other parts of the
ISO/IEC 20000 series provide supporting guidance.
ITIL is introduced in the ITIL® Foundation – ITIL 4 Edition publication as:
“ITIL has led the ITSM industry with guidance, training and certification (qualifications) programmes
for more than 30 years. ITIL 4 brings ITIL up to date by reshaping most of the established ITSM (IT
service management) practices in the wider context of customer experience, value streams, and digital
transformation, as well as embracing new ways of working, such as Lean, Agile and DevOps.”
“ITIL 4 provides the guidance organizations need to address new service management challenges and utilize
the potential of modern technology. It is designed to use a flexible, coordinated and integrated system for
the effective governance and management of IT-enabled services.”
AXELOS has agreed on the development of this document. ITIL, including the ITIL manuals, is owned by
AXELOS.
Organizations can implement and improve their SMS using the requirements specified in ISO/IEC 20000–
1, the guidance in the other parts of the ISO/IEC 20000 series and ITIL. Both the ISO/IEC 20000 series
and ITIL provide guidance to plan, design, transition, deliver and improve services that create value to
the business and its customers. An organization can adopt ITIL guidance to support the management
of their services in alignment with the requirements specified in ISO/IEC 20000–1. Other guidance can
also be used to support ISO/IEC 20000–1.

4 ISO/IEC 20000–1 and ITIL 4
4.1 Introduction to ISO/IEC 20000–1
ISO/IEC 20000-1 specifies requirements for establishing, implementing, maintaining and continually
improving a service management system (SMS). An SMS supports the management of the service
lifecycle, including the planning, design, transition, delivery and improvement of services, which
meet agreed requirements and deliver value for customers, users and the organization delivering the
services. The organization in the scope of the SMS can be a whole or part of a larger organization and
can also be known as the service provider.
ISO/IEC 20000-1 is intentionally independent of specific guidance. The organization can use a
combination of generally accepted frameworks (e.g. ITIL) and its own experience. Appropriate tools for
service management can be used to support the SMS.
All requirements specified in ISO/IEC 20000-1 are generic and are intended to be applicable to all
organizations, regardless of the organization’s type or size, or the nature of the services delivered.
While it can be used ‘regardless of the organization’s type or size, or the nature of the services
delivered’, ISO/IEC 20000-1 has its roots in IT. It is intended for service management of services using
technology and digital information. The examples given in this document illustrate a variety of uses of
ISO/IEC 20000-1.
Exclusion of any of the requirements in ISO/IEC 20000-1:2018, Clauses 4 to 10, is not acceptable when
the organization claims conformity to ISO/IEC 20000-1, irrespective of the nature of the organization.
The organization cannot demonstrate conformity to the requirements specified in ISO/IEC 20000-1 if
other parties are used to provide or operate all services, service components or processes within the
scope of the SMS.
ISO/IEC 20000-10 includes the concepts for an SMS, the vocabulary used for the ISO/IEC 20000 series,
a description of each part of the series and related standards. The vocabulary is split into subclause 3.1
for terms common to management system standards, subclause 3.2 for terms specific to service
management used in ISO/IEC 20000-1 and subclause 3.3 for terms used in the rest of the ISO/IEC 20000
series. Subclauses 3.1 and 3.2 are the same as in ISO/IEC 20000-1.
Guidance is available in other parts of the ISO/IEC 20000 series in the form of :
— ISO/IEC 20000-2 (Guidance on the application of service management systems),
— ISO/IEC 20000-3 (Guidance on scope definition and applicability of ISO/IEC 20000-1),
— ISO/IEC 20000-5 (Exemplar implementation plan for ISO/IEC 20000-1),
— ISO/IEC 20000-6 (Requirements for bodies providing audit and certification of service management
systems) and
— ISO/IEC 20000-7 (Guidance on the Integration and Correlation of ISO/IEC 20000-1:2018 to
ISO 9001:2015 and ISO/IEC 27001:2013).

4.2 Introduction to ITIL 4
4.2.1 General
ITIL 4 was published by AXELOS in 2019 as an evolution of previous versions. ITIL 4 has a new
architecture and scope. It aims to connect various approaches to the management of digital technology
into a holistic and comprehensive framework to address IT service management.
The key components of the ITIL 4 framework are the four dimensions model and the ITIL service value
system.
4.2.2 The four dimensions model
To support a holistic approach to service management, ITIL defines four dimensions that collectively
are critical to the effective and efficient delivery of value for customers and other stakeholders in the
form of products and services. The four dimensions are:
— Organizations and people: define the way an organization is managed, the roles and responsibilities
and authorities, and communication;
— Information and technology: define the information and knowledge necessary for the management
of services and the technologies required;
— Partners and suppliers: define an organization’s relationships with other organizations that are
involved in the services, including contracts and other agreements;

---------------------- Page: 8 ----------------------
ISO/IEC TS 20000-11:2021(E)

— Value streams and processes: define how the various parts of an organization work in an
integrated and coordinated way to enable value creation through the services.
The four dimensions represent perspectives which are relevant to the whole SVS, including the entirety
of the service value chain and all ITIL practices. The four dimensions are constrained or influenced
by external factors such as political, economic, social, technological, legal or environmental (PESTLE),
which are beyond the control of the service value system.
4.2.3 The ITIL service value system
The ITIL service value system (SVS) represents how the various components and activities of the
organization work together to facilitate value creation. ITIL calls this value co-creation, to indicate
that value is created together by the organization, its customers and other organizations in the service
relationship. The core components of the ITIL SVS, as shown in Figure 2, are:
— governance;
— continual improvement;
— the ITIL guiding principles;
— the ITIL service value chain;
— the ITIL practices.

4.2.4 Governance
Governance is the means by which an organization is directed and controlled. The role and position of
governance in the ITIL SVS will vary depending on how the SVS is applied in an organization.

4.2.5 Continual improvement
Continual improvement is a recurring organizational activity performed at all levels to ensure that an
organization’s performance continually meets stakeholders’ (interested parties’) expectations. ITIL 4
supports continual improvement with the ITIL continual improvement model which includes the steps
shown in Figure 3.

4.2.6 The ITIL guiding principles
The ITIL guiding principles are recommendations that can guide an organization in all circumstances,
regardless of changes in its goals, strategies, type of work or management structure. They are universal
and enduring and represent the core messages of ITIL and of service management, supporting successful
actions and good decisions of all types and at all levels. They can be used to guide organizations in
their work as they adopt a service management approach and adapt ITIL guidance to their own specific
needs and circumstances. The seven ITIL guiding principles are:
— Focus on value. Everything that the organization does needs to map, directly or indirectly, to value
for the stakeholders.

---------------------- Page: 10 ----------------------
ISO/IEC TS 20000-11:2021(E)

— Start where you are. Do not start from scratch and build something new without considering what
is already available to be leveraged.
— Progress iteratively with feedback. Do not attempt to do everything at once; organize the work
into smaller manageable segments for better results and ongoing improvement through feedback.
— Collaborate and promote visibility. Working together across boundaries produces results that
have greater acceptance, more relevance to objectives and increased likelihood of long-term success.
— Think and work holistically. No service, or element used to provide a service, stands alone. Taking
a holistic approach to service management includes establishing an understanding of how all the
parts of an organization work together in an integrated way.
— Keep it simple and practical. If a process, service, action or metric fails to provide value or produce
a useful outcome, eliminate it. Use the minimal number of steps to achieve the objective.
— Optimize and automate. Resources of all types, particularly human resources, should be used to
their best effect. Eliminate anything that is truly wasteful and use technology to achieve whatever
it is capable of. Human intervention should only happen where it really contributes value.
4.2.7 The ITIL service value chain
The central element of the SVS is the service value chain, an operating model which outlines the key
activities required to respond to demand and facilitate value realization through the creation and
management of products and services. The ITIL service value chain includes six value chain activities,
as shown in Figure 4:
— Plan: Ensure a shared understanding of the vision, current status and improvement direction of all
services in the organization;
— Improve: Ensure continual improvement of products, services and practices across all value chain
activities and the resources in the four dimensions of service management;
— Engage: Ensure transparency, continual engagement, good relationships and a good understanding
of stakeholder needs;
— Design and transition: Ensure that services continually meet stakeholder expectations for quality,
costs and time to market;
— Obtain/build: Ensure that service components are available when and where they are needed and
meet agreed specifications;
— Deliver and support: Ensure that services are delivered and supported to agreed specifications
and stakeholders’ expectations.

4.2.8 The ITIL practices
Practices are sets of organizational resources designed for performing work or accomplishing an
objective. They consider resources required across each of the four dimensions of service management
for a more holistic approach to achieve a successful outcome. These are distinct from processes, which
are sets of interrelated or interacting activities that transform inputs into outputs. Processes define the
sequence of activities and their dependencies and can be part of practices within the value stream and
processes dimension. The ITIL SVS includes 14 general management practices, 17 service management
practices and three technical management practices, as shown in Table 1.

4.2.9 Value streams
A value stream is a series of steps an organization undertakes to create and deliver products and
services to consumers. These steps can be seen as journeys through the six value chain activities for
specific scenarios or types of demand. They use resources of the service provider and the service
consumers to generate required outputs, such as resolving an incident or designing a new service.
4.3 Relationship between ISO/IEC 20000–1 and ITIL
ISO/IEC 20000–1 and ITIL are not based on each other, but they have features in common and there
are relationships between the two. There is a strong correlation between most of the ISO/IEC 20000-1
requirements and ITIL guidance. Refer to Annex B for detailed correlation.
Using ISO/IEC 20000–1 and ITIL together can support organizations intending to implement and derive
the benefits from service management. For organizations that wish to demonstrate conformity with
the requirements specified in ISO/IEC 20000–1, ITIL can be a starting point. Implementation teams can
take the basic principles and approaches suggested by ITIL and adapt the framework to their service
management objectives, organizational structure, existing roles and culture, ensuring that they meet
the requirements of ISO/IEC 20000-1. For example, ITIL is a source of guidance that can be used to meet
the requirements in ISO/IEC 20000-1:2018, Clause 8 and other clauses.
As ISO/IEC 20000-1 specifies the critical aspects of service management, it can be used as an approach
to navigate through the critical parts of service management frameworks such as ITIL. This can be
achieved by looking at the ISO/IEC 20000 requirements and guidance before examining the more
detailed guidance that can be found in the framework(s) of choice. This approach can therefore
help organizations to identify and establish a solid foundation for service management that can be
continually improved. Once the processes have been implemented, the organization can conduct a gap
analysis to see what improvements can be implemented.
