ITIL® Processes and Functions – ITIL Course

Introduction

In ITIL® (Information Technology Infrastructure Library), processes and functions are fundamental concepts that structure IT Service Management (ITSM).

  • Processes are structured activities with defined inputs and outputs, designed to achieve a specific objective.
  • Functions are teams or groups of people and tools that carry out certain activities or provide capabilities to deliver services.

Understanding the distinction between processes and functions is crucial for ITIL exam preparation and practical ITSM implementation.
