Companies adopting ITIL® best practices are on the rise because it is a proven cost- effective, efficient way for IT managers to maximize the control their IT infrastructure. The ITIL® process follows two diagrams: ITIL® Jigsaw and the ITIL® BS15000. The ITIL® process demo diagram explained below is the Jigsaw Diagram and is one of the two diagrams used by ITIL® training schools today.
The Jigsaw Diagram shows five principal elements of ITIL® drawn like a jigsaw puzzle. The concept of this ITIL® process demo diagram is that the major elements of ITIL® can be linked together like a jigsaw puzzle–some of the pieces may fit perfectly and some may not. The overlapping pieces represent the need to integrate each process of the diagram. They are the business perspective, service delivery, service support, ICT infrastructure management and applications management
The business perspective illustrates the strategic level of the ITIL® Jigsaw and will discuss issues on continuity management, partnerships, change survival and change in business practice.
Service delivery covers the management of the applications in a tactical level and will include capacity management, financial management for IT services, service level management, availability management and continuity of IT service. If continuous service delivery is important, service support will equally be just as important because it will ensure that the customer or user has continuous access to the IT service. Service support covers the service desk, incident, problem, configuration, release and change management.
ICT infrastructure management is the core of service delivery and support while the applications management identifies the issues of change and will provide a solution to the situation.
The Jigsaw Diagram is an ITIL® process demo diagram which shows how different pieces can fit together to form one common goal.
