ITSM integrates people, processes and technology to deliver the desired quality of service. ITIL is a set of IT service management concepts and practices (ITSM) focused on aligning IT services with business needs, and ISO is the largest international standards and standards organization made up of representatives of various standardization bodies.

While ISO consists of six groups into which standards are divided, such as: information security, continuity, resilience and recovery, risk management and compliance, quality management, IT governance and service management, health, safety and sustainability.
