3.The ITIL Framework and Its Core Concepts
The ITIL framework divides the management of services into five.
- Strategic Service: Goal establishment.
- Service Design: The construction of new or the enhancement of existing services.
- Service Transition: Intended changes.
- Service: Information technology service provision and support.
- Continuous Service Enhancement: the quantification and continuous improvement of service.
The different services are the various components of a machine, and when combined, they work together to bring the value of predictability to clients.

6. Incident Management vs. Problem Management
- One of the most frequently asked ITIL quadrant questions is whether incident management or problem management is more effective. These strategies are:
- Incident management is reactive, trying to have service available on time.
- Problem management is proactive, attempting to detect and eliminate factors that cause interruptions in service delivery.
That is, incident management will extinguish the fire, and problem management will prevent it from reigniting. They create the micro foundation of excellence in IT operations.
7. ITIL has disadvantages and advantages.
