ITIL® Processes and Functions – ITIL Course
Introduction
In ITIL® (Information Technology Infrastructure Library), processes
and functions are fundamental concepts that structure IT Service

activities or provide capabilities to deliver services.
Understanding the distinction between processes and
functions is crucial for ITIL exam preparation and practical ITSM
implementation.
