What is ITIL?
ITIL, or Information Technology Infrastructure Library, is a globally recognized framework of best practices for delivering high-quality IT service management (ITSM). It provides organizations with standardized processes, roles, and guidelines to align IT services with business needs—ensuring efficient, reliable, and value-driven service delivery.
Understanding what is ITIL is essential for businesses aiming to optimize IT operations, improve customer satisfaction, and ensure consistency across service management activities.

ITIL helps organizations:
- Streamline IT support processes
- Improve service delivery and performance
- Reduce risks and operational costs
- Ensure compliance with regulations and SLAs
- Continuously improve IT services based on feedback and metrics
ITIL is not a rigid set of rules—it’s a flexible, scalable framework that can be adapted to organizations of all sizes and industries.
Core Components of ITIL:
- Service Strategy – Defines goals, service portfolios, and financial planning
- Service Design – Creates service architecture, SLAs, and policies
- Service Transition – Manages changes, deployments, and knowledge transfer
- Service Operation – Handles incident management, requests, and monitoring
- Continual Service Improvement (CSI) – Uses metrics and feedback for optimization
These components help organizations design, deliver, and improve IT services in a structured and measurable way.
