What is ITIL? Everything you Need to Know

ITIL is a set of best practices, processes, and guidelines for delivering IT services to customers. The main focus is to increase the value of the service to the business or customers and align it with business requirements and needs. ITIL contains detailed descriptions for processes, flows, success factors metrics, and transformation guidelines which can be adapted by the organization to work in their environment.

Each individual process has acknowledged value to the business and can be implemented separately.
