Understanding ITIL and its Importance

ITIL is a set of detailed practices for IT service management that align IT services with business needs.
ITIL helps businesses collaborate with the IT team to deliver IT services to stakeholders.

The ITIL service value system consists of the four dimensions model, which includes organizations and people, information and technology, partners and suppliers, and value streams and processes.
Organizations and people in an organization should understand their roles and responsibilities and how they add value to the organization.
Information and technology encompasses the knowledge, techniques, and technologies needed for service management.
Partners and suppliers focus on the organization's relationships with businesses involved in design, deployment, delivery, support, and continuous improvement of services.
Value streams are a series of steps followed by an organization to create and deliver products or services, while processes improve productivity within or across organizations.
The service value system includes guiding principles, governance, service value chain, continual improvement, and management practices.
Guiding principles provide a comprehensive understanding of how an organization should manage a service.
Governance is responsible for controlling and monitoring the organization, adapting to guiding principles or defining its own.
The service value chain comprises activities performed by a business to provide valuable products or services.
Continual improvement ensures that services are continuously aligned with customer expectations.
Management practices are divided into general management, service management, and technical management practices.
