When following ITIL guidelines, companies should begin by evaluating their IT departments. Their first task is to identify those processes and areas most in need of improvement. They must then develop a model process for the IT department to adopt.
Those processes that quickly lead to noticeable improvements in service for customers or users should be prioritized to achieve “quick wins”. These processes are described in the Service Delivery and Service Support chapters of ITIL.
The Service Support chapter describes ongoing processes within an IT organization. These can be viewed as baseline or added processes and include incident and problem management, as well as change, release and configuration management. Service Delivery comprises service level, financial, capacity, availability and continuity management. Key areas include planning, coordination and control of IT services, as well as clear definition of service level agreements.
