ITIL®: Definition and objectives

[DEFINITION][ITIL®][ITIL® (Information Technology Infrastructure Library) is a globally recognized framework for IT service management (ITSM). It provides a structured approach to planning, delivering, and improving IT services. The goal is to align services optimally with business requirements and customer expectations. Through established best practices, ITIL® helps organizations standardize processes, use resources efficiently, and improve service quality in the long term.]

The aim of ITIL® is to support organizations in the continuous improvement of their IT services and to consistently align them with business requirements. With ITIL® Version 5, this claim is expanded to include a stronger product, value stream, and automation perspective. The focus is particularly on the following aspects:

• Improve service quality: ITIL® provides best practices for delivering services consistently, reliably, and in accordance with defined standards.
• Increase efficiency: Standardized processes improve resource utilization, reduce costs, and increase operational performance. ITIL® Version 5 also emphasizes automation and integrated value streams.
• Promoting customer satisfaction: ITIL® consistently aligns services with customer needs. Important factors include fast response times, transparent communication, and clearly recognizable added value.

ITIL® Version 5: Classification and key innovations

With the new ITIL® Version 5 (often referred to in the market as ITIL® 5 or "The new ITIL" by PeopleCert), the framework has been specifically adapted to the requirements of modern digital organizations. The version is intended as an evolution that builds consistently on ITIL® 4 and retains proven concepts such as the Service Value System and the Guiding Principles.

A key focus is on the holistic management of digital products and services. ITIL® Version 5 takes into account the reality that value creation is increasingly taking place via platforms and integrated ecosystems. In doing so, the framework breaks down traditional silos: it is no longer aimed solely at IT, but offers a common language for product management, specialist departments, and executives. In addition to efficiency, customer experience and employee experience are also becoming key strategic success factors.

Technological developments are now also more deeply entrenched. ITIL® Version 5 is explicitly designed to be AI-native and provides guidance in complex, AI-supported environments. Topics such as automation, data-driven decisions, and sustainable digital operating models are an integral part of this. Governance is more clearly separated from operational management and strategically strengthened.

Overall, the new version introduces an extended product and service lifecycle that enables consistent, value-oriented management from the initial idea to stable operation. Foundation training courses and special bridge formats are available to help you get started in a structured way, supporting the transition from ITIL® 4 to ITIL® Version 5.

Origin, history and versions of ITIL®

Today's ITIL® concepts are the result of continuous development. A look at their origins and versions helps to better understand this development.

ITIL® was initiated by the British government in the 1980s to improve the quality and efficiency of IT services in the public sector. Today, the framework is further developed by the rights holder and certification provider PeopleCert and distributed via a global network of accredited training providers.

The development of ITIL® shows continuous adaptation to technological and organizational changes:

ITIL® v1 (1989): Focus on a collection of best practices for IT services. The goal was the systematic improvement of IT services in public and private organizations.

ITIL® v2 (2001): Greater structuring and focus on key ITSM processes, including incident management and problem management. The publications Service Support and Service Delivery established themselves as key references.

ITIL® v3 (2007): Introduction of the five-phase service lifecycle: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. The focus was on holistic management across the entire lifecycle of IT services.

ITIL® 4 (2019): Refocus on value creation, collaboration, and flexibility. ITIL® 4 integrates approaches such as Agile, DevOps, and Lean. Key concepts are the Service Value System and the Guiding Principles.

ITIL® Version 5: Further development of ITIL® 4 for a digital and product-centric working environment. ITIL® Version 5 strengthens the integration of digital products, value streams, and governance. In addition, the framework increasingly takes into account automation, AI-supported processes, and platform ecosystems. An expanded lifecycle model for products and services supports consistent, value-oriented management.

ITIL® has thus evolved from a process-driven approach to a flexible, value- and product-oriented framework that reflects the requirements of modern organizations.

Phases and core topics (according to ITIL® 3)

In ITIL® 3, the service lifecycle formed the central frame of reference for IT service management. It structured planning, provision, and improvement along a continuous lifecycle.

The service lifecycle comprises five core phases:

1. Service Strategy

Goal: Strategic planning of IT services in line with business objectives
Core topics: Service portfolios, customer requirements, cost management

2. service design

Goal: Designing services in accordance with functional and technical requirements
Core topics: SLAs, availability, service catalog

3. service transition

Goal: Introduction and modification of services with minimal disruption
Key topics: Release and change management, knowledge provision

4. service operation

Goal: Stable operation and user support
Core topics: Incident management, problem management, access control

5. Continuous Service Improvement

Goal: Continuous analysis and optimization of services
Core topics: Improvement measures, quality management

With ITIL® 4, the lifecycle was replaced by a value stream-oriented model based on the Service Value System and flexible management practices. ITIL® Version 5 further develops this approach and expands it to include a product-centric perspective and an integrated Product & Service Lifecycle.

However, the fundamental ideas from ITIL® 3 remain relevant, especially as a conceptual basis and for classifying historical process models.

Service Value System in ITIL® 4 and ITIL® Version 5

In ITIL® 4, the Service Value System (SVS) forms the central framework for the creation, provision, and continuous improvement of services. It supports organizations in creating value for customers and the company and in responding flexibly to change.

The Service Value System (SVS) remains a fundamental structural model in ITIL® Version 5. However, the operational value creation logic has been further developed: The Service Value Chain from ITIL® 4 has been replaced by a Product & Service Lifecycle, which reflects a more product-oriented perspective and modern digital value streams.

The SVS from ITIL® 4 comprises five core elements:

1. Guiding Principles
The Guiding Principles are universal recommendations for action. They support organizations in their decision-making and promote a consistent approach.

2. Governance
Governancedescribes structures and guidelines for strategic management. It encompasses goal alignment, decision-making, and performance monitoring. In ITIL® Version 5, governance is positioned more strongly as an independent strategic discipline.

3. Service Value Chain
TheService Value Chainis a central element of ITIL® 4 and comprises six activities:

• Plan: Definition of vision, goals, andguidelines
• Improve: Continuous optimization of services and processes
• Engage: Interaction with customers and stakeholders
• Design & Transition: Development of new or modified services
• Obtain/Build: Provision of the required resources
• Deliver & Support: Operation and support of services

The interaction of these activities creates value streams through which services and products are developed, provided, and continuously optimized.

In ITIL® Version 5, the service value chain as a central control model is replaced by an extended product and service lifecycle. This more realistically reflects the end-to-end value creation of digital products and services and comprises eight activities:

• Discover: Identification of opportunities, requirements, and ideas for new or improved products and services
• Design: Conceptualization of product and service solutions, taking into account professional and technical requirements
• Acquire: Procurement of resources, technologies, or partner services for implementation
• Build: Development and implementation of product and service components
• Transition: Introduction of new or modified products and services into operational use
• Operate: Ensuring stable operational processes and continuousservice provision
• Deliver: Provision of services and product functionalities for users customers
• Support: Providing assistance to users ensuring stability, maintenance, and further development

The product and service lifecycle thus reflects a more product-oriented perspective and addresses modern digital value creation models and integrated end-to-end responsibility.

4. Practices
Practicesreplace the previous processes in ITIL® 4. They include activities, resources, and capabilities for managing services. In total, ITIL® 4 defines 34 management practices that can be flexibly combined. This practice-based approach will remain in ITIL® Version 5.

5. Continual Improvement
Continual improvement permeates the entire SVS. Organizations are continuously encouraged to optimize processes, technologies, and services. In ITIL® Version 5, this approach is more closely linked to value stream management and maturity models.

The goal of the Service Value System
‍TheSVS ensures that all activities within an organization are focused on value creation. It combines strategy, governance, practices, and value streams into an integrated management approach for services and digital products.

Guiding Principles of ITIL® 4 and ITIL® Version 5

The seven Guiding Principles form a central framework in ITIL®. They are deliberately kept general and can be applied regardless of organizational size, technology, or working model. The principles remain unchanged in ITIL® Version 5 and support organizations in making decisions in service and product management.

1. Focus on value-
Organizationsshould consistently focus on customer value and provide services that generate measurable benefits.

2. Start where you are
Existingresources, skills, and practices are analyzed and developed in a targeted manner instead of being completely rebuilt.

3. Take an iterative approach and use feedback
Shortdevelopment cycles enable quick results and continuous learning through feedback.

4. Promote collaboration and transparency
Opencommunication and cross-functional collaboration improve decision-making quality and implementation speed.

5. Think and work holistically
Services, products, and organizational units are viewed as an interconnected system in order to reduce dependencies.

6. Keep it simple and practical
Complexityis reduced by only implementing necessary activities and regularly questioning structures.

7. Optimize and automate
‍Afteroptimizing working methods, automation supports greater efficiency and stability. In ITIL® Version 5, this approach gains additional significance through AI and platform integration.

Other important concepts in ITIL®

Other concepts from ITIL® form the central foundations of IT service management (ITSM). They support organizations in designing services and digital products efficiently and creating sustainable added value.

1. value creation through benefits and guarantee

Value creation is at the heart of ITIL®. It describes the benefits that customers or organizations receive from services and products. The two key components, utility (benefit) and warranty, must be fulfilled together in order to create value.

Utility (benefit):
Describeswhat a service does. A service generates utility when it fulfills requirements or solves problems.

Warranty:
Describes the requirements for availability, capacity, continuity, and security. They create trust in reliability and stability.

The goal of ITIL® is to ensure that services and products offer both utility and warranty. Organizations are encouraged to consistently prioritize customer value when making decisions.

2. stakeholders

ITIL® emphasizes collaboration between internal and external stakeholders. These players play a crucial role throughout the value chain and in the product and service lifecycle.

Key stakeholders are:

Organizations or individuals who realize the benefits of a service and define expectations regarding its value.

users end users):
People who interact directly with the service. Their feedback supports optimization and further development.

Service Provider:
Organizations that provide and manage services. They are responsible for compliance with utility and warranty requirements.

Supplier:
Partners or suppliers who contribute to the provision of a service or product.

The involvement of all stakeholders enables effective development and provision of services. ITIL® promotes cross-functional collaboration and transparency.

3. key performance indicators (KPIs) and measurability

ITIL® places great emphasis on measurability. Through systematic data analysis, organizations can evaluate the effectiveness of services and value streams and continuously improve them.

Key performance indicators (KPIs) serve as central metrics in this context:

Measuring target achievement:
KPIs evaluate the degree to which targets have been achieved, e.g., the average processing time for an incident ticket.

Identify potential for improvement:
KPIs reveal weaknesses and support targeted optimization measures.

Creating transparency:
KPIs provide an objective basis for communicating performance and value to stakeholders.

The data-driven approach helps organizations make value-based decisions and implement continuous improvement across services, products, and value streams.

ITIL® in practice

ITIL® is more than just a theoretical framework. Its strength lies in its practical application. With established practices, methods, and tools, ITIL® supports organizations in the efficient management of IT services and digital products.

Key approaches in practice are:

1. service level agreements (SLAs)

SLAs are contractual agreements between a service provider and customers. They define service objectives and set out the expectations of both parties.

Typical SLA metrics are:

Availability:
, e.g., 99.9% uptime per month

Response times for incidents:
e.g., initial contact within 30 minutes

In practice, it is important to make SLAs realistic and measurable. This ensures customer satisfaction and prevents teams from becoming overloaded.

2. operational level agreements (OLAs)

OLAs are internal agreements between teams or departments. They support SLA compliance through clear responsibilities and coordinated processes.

While SLAs are customer-oriented, OLAs regulate internal collaboration. They promote transparency, coordination, and efficient service delivery.

3. configuration management database (CMDB)

The Configuration Management Database (CMDB) is a central tool in IT service management. It contains information about configuration items (CIs) and their relationships.

Examples of CIs are:

Hardware: Servers, network devices, end devices
Software: Applications, operating systems, platforms

The central database enables a better understanding of dependencies and the effects of changes. This supports informed decisions, stable services, and effective incident and change management.

ITIL® certifications and further information

Understanding and applying ITIL® is an important skill in IT service management. Official certifications enable structured proof of competence through standardized training and examinations. They support professionals in deepening their knowledge and demonstrating their qualifications in service and product management.

The certification structure is modular and covers various levels of experience and areas of specialization. Entry is usually via foundation certifications, while advanced modules enable in-depth study and specialization.
