Information Technology Infrastructure Library (ITIL) is designed to standardize how IT services are selected, planned, delivered, and supported. ITIL guidelines and best practices align IT actions and expenses to business requirements.

ITIL traces its roots past the 1980s as data centers began decentralizing. This approach's flexibility also led to differences in deployments that created inconsistencies. The United Kingdom's government recognized the importance of applying for the ITIL v4 certification training program consistent practices across all IT services and introduced ITIL to help companies ensure predictable service levels.

The ITIL framework has five books periodically reviewed and updated as technologies change. Each book contains best practices for a significant aspect of the IT service lifecycle.

1. ITIL Service Strategy - specifies that each stage of the service lifecycle must be focused on defined individual business goals, requirements, and service management principles
2. ITIL Service Design - guides the production and maintenance of IT policies, architectures, and documents that support IT services
3. ITIL Service Transition - focuses on change management and guides transitioning new and updated services into the business environment
4. ITIL Service Operation - focuses on strategies to support service delivery and maintenance
5. ITIL Continual Service Improvement - focuses on processes for identifying and introducing service management improvements and lifecycle management

What is ITIL V4? What does ITIL V4 focus on?

A process is a set of related activities, but the practice also covers the context and policy behind the process. Processes are a subset of rules, but be careful to assume that ITIL 4 practices are the same as ITIL v3 processes.

All of that said, ITIL 4 practices emphasize relevance and flexible nature, and they are all adaptable to real-world organizations. Let's take the principles of Incident Management, for example. Restoring regular service means focusing on the customer's needs and getting the customer up and running as soon as possible. 

It means minimizing service disruption and customer inconvenience as much as possible. This principle is not just relevant to IT but in any service delivery environment. With Incident Management, the service provider's responsibility is to investigate ways of minimizing service disruption and maintaining customer focus.

Is it Worth Getting ITIL V4 Certification?

As ITIL 4 is revealed in more depth and the ITIL practices are expanded on in the Practice Guides, you will see more and more opportunities for analyzing the relevance and adaptation of each course to suit varying environments.

From the top of my head, ITIL V4 is composed by:

• Six guiding principles (very similar to the agile manifesto)
• Four service dimensions (a rebranding of the 4P's of Design)
• 34 practices (a new concept that mixes what was known as processes and functions)

Also, the Service Value System and the Service Value Chain are brand new concepts (for ITIL) and pretty much change the approach to service models.

It now includes (or will consist of in the future) Enterprise architecture, project management, and software development. All of which were out of scope in V3.

That said, right now, ITIL V4 is very abstract.
