What is ITIL 4 and How It Improves Modern Service Management

In today’s world, businesses rely heavily on IT services. Whether it’s supporting customers, running apps, or managing data, IT plays a key role in keeping operations smooth. ITIL 4 is a framework that helps organisations manage their IT services better and deliver real value to their customers. In this article, I am going to look at the differences between ITIL v3 and ITIL 4. Lets look at that together in this article.

What is ITIL 4?

ITIL 4 stands for Information Technology Infrastructure Library, version 4. It is the newest version of ITIL and focuses on modern service management. Unlike older versions, ITIL 4 is flexible, practical, and aligns IT with business needs.

It helps organisations:

Plan and deliver IT services efficiently.
Improve service quality.
Keep up with fast-changing business environments.
Work with modern ways of working like Agile, DevOps, and Lean.

In short, ITIL 4 is about making IT services more valuable and effective for both the business and its customers.

Key Parts of ITIL 4

#1 Service Value System (SVS)

This is a core part of ITIL 4. It shows how all activities and processes work together to create value. It includes:

#1 Guiding Principles

These are simple rules to help make the right decisions.It contains best practices which can be found anywhere. They are rules and practrices that have been used in several organisations and it has worked. This can be replicated in other organisations.

#2 Service Value Chain

These are the steps that can be taken in order to acheive the desired values. Here we have series of activities that organisations can implement anytime they are planning to deliver value. These steps are interdependent and has to be done together depending on what the organisation is trying to achieve.

#3 Practices

These are series of activities that are borrowed from other management practices/ They are 34 activities and processes that help manage services. These can be implemented in various organisations in order to deliver value and do business from customers perspective.

#4 Continual Improvement – always looking for ways to make services better.

There is one problem that is very common with organisations. They tend to relax immediately when they notice that the system is working perfectly. They will not bother to analyse the system to determine what can be changed. This is bad idea. Organizations have to be committed to continuous improvement. They need to have a dedicated team that will anlayse the system in order to determine what can be changed.

Four Dimensions of Service Management

ITIL 4 reminds organizations to look at IT from four angles:

#1 Organizations & People

The first major aspect of ITIL 4 has to do with organisation and people. We have to ensure that the organisation has the right structure that support growth. There must be specialties that are developed to deliver value to customers. We also have people who happen to be employees in an organisation that have been immersed in the culture of the organisation and are ready to deliver value to customers.

#2 Information & Technology

We also talk of Information and Technology that supports growth and help organizations to deliver value. The company has to ensure that customer data are well organised and preserved. They also need to invest in technologies that will allow them to discovers patterns that are very common to their customers. This will help them to come up with products and services that satisfy customers needs.

#3 Partners & Suppliers

When you are trying to serve your customers, most times , it might be difficult to do so directly without making use of Partners and Suppliers. As a Service oriented organisation, you need to make sure that you and your Partners and Suppliers are on the same page as far as service to customers are concerned. You should not allow your Parnners and Suppliers to misrepresent you.

#4 Value Streams & Processes

This has to do with steps and activities that are combined together in order to deliver value to customers. You should alwauys analyse your activities in order to confirm whether they actually delivering values. This will also allow you to discover non value adding activities that are not allowing you to serve customers better.
