ITIL
ITIL (Information Technology Infrastructure Library) is a set of detailed practices for IT service management that focuses on aligning IT services with business needs. Think of it as an instruction manual for how IT departments should operate to provide the best service to their organization. It's like having a standardized playbook that helps IT teams handle everything from customer service requests to major system changes in an organized way. Companies use ITIL to make sure their IT services are reliable, efficient, and follow best practices. It's similar to having a quality management system, but specifically for IT services.
