Are you new to ITSM and ITIL? Wondering how they fit together in the world of IT services?
You’re in the right place.
In this blog, we’ll break down ITSM and ITIL in simple, human language. Whether you’re an IT student, business owner, or tech professional, this guide will help you understand the basics and why they matter.
What is ITSM (IT Service Management)?
ITSM stands for Information Technology Service Management.
It’s the practice of designing, delivering, managing, and improving the way IT services are used within an organization.
Think of ITSM as a structured way to deliver IT support handling everything from system issues to software installations.
Common ITSM Examples:
- Resetting passwords
- Fixing server issues
- Approving software access requests
- Managing IT assets like laptops or routers
Goal of ITSM: To ensure IT services align with business goals and offer maximum value.
What is ITIL (Information Technology Infrastructure Library)?
ITIL is not a tool or software. It’s a framework of best practices for ITSM.
In simple terms, ITIL tells you how to do ITSM efficiently and effectively.
Originally developed by the UK government, ITIL has become the world’s most widely adopted approach for IT service management.
