What’s ITIL 4 Certification?

ITIL is a standard set of structured rules used to manage IT services. It stands for Information Technology Infrastructure.

Example:

Think about an e-commerce company during a sales event. Suddenly the payment gateway shuts down due to too many people trying to checkout at the same time. So customers can’t complete their orders leading to affect in the revenue.

The support team can jump right in and start troubleshooting, but it would be more time consuming and random. This is where the ITIL framework introduces guided stages to approach these issues such as,

  • Identify the issue: The team can point out the failure is caused due to high traffic
  • Resolve efficiently: The team removes the issue and fixes it.
  • Prevent it from happening again: Methods are implemented to prevent this from recurring.

This is why certified professionals are in demand. Because they fix issues from the root and manage everything efficiently.
