1. Four Dimensions of ITIL 4
ITIL 4, which stands for Information Technology Infrastructure Library 4, is a
framework for managing IT services and processes. It introduces several key
concepts and dimensions to help organizations align their IT service management
(ITSM) practices with modern business needs. One of the central ideas in ITIL 4 is
the Service Value System (SVS), which comprises several dimensions. The four
core Dimensions of ITIL 4 are:
1. Organizations and People: This dimension emphasizes the importance of
the people within an organization and the culture, structure, and roles they
play. It recognizes that successful IT service management requires
competent and motivated individuals working together effectively. It
focuses on roles, responsibilities, and collaboration within the organization.
2. Information and Technology: This dimension highlights the role of
technology and data in delivering value to the organization and its
customers. It emphasizes the need for well-managed IT assets, data, and
technology to support service delivery. Effective use of technology and data
can lead to better decision-making and improved service delivery.
3. Value Streams and Processes: This dimension focuses on how organizations
create value for their customers through well-defined processes and
workflows. It encourages organizations to identify and optimize value
streams that deliver products and services. This includes designing efficient
processes, automation, and continuous improvement practices.
4. Partners and Suppliers: In today's interconnected world, many
organizations rely on external partners and suppliers to deliver their
products and services. This dimension emphasizes the importance of

2. building and managing effective relationships with these external entities.
It's crucial to ensure that partners and suppliers align with an organization's
goals and deliver value as expected.
These four dimensions work together within the Service Value System (SVS) to
help organizations create, deliver, and continually improve value for their
customers and stakeholders. ITIL 4 provides guidance and best practices for
integrating these dimensions into an organization's IT service management
strategy, ensuring a holistic and customer-centric approach to ITSM.
