ITIL3 is actually a way of delivering value to the customers by providing them with efficient outcomes that they want to enjoy without owning the risk and cost. On the other hand, ITIL4 is a way that allows the value co-creation that provides the customers with fantastic results, and the best thing is that customers don’t have to manage specific costs and risks.
First of all, let’s discuss the difference between the processes of processes. If we talk about ITIL3, we come to know that it was a framework that gave much importance to processes. It urged the practitioners to apply ITIL by the book, which dragged them to a complicated web of solutions. On the other hand, ITIL4 is more efficient in this approach. It does not idealize the process; instead, it stimulates the practitioners to implement the same ITIL.
Guiding principles of both ITIL3 and ITIL4:
ITIL provides the practitioners with seven guiding principles, which serve as an array of recommendations to escort an organization about its services management lifecycle. It isn’t concerned about the changes it has to face in goals, perspectives, strategies, and the organization’s structure.
If we talk about the service lifecycles of ITIL3, we get to know that it was quite complicated to follow them all. Thanks to ITIL4, that eradicated the troubles of all the service lifecycles that were in ITIL3. Expert ITIL introduced an advanced operating model with the name of Service Value System (SVS), which is way more efficient in describing the component concepts and providing efficient ITSM.
4 Ps of service design:
Let’s talk about 4 Ps to the four dimensions. ITIL3 proves the 4 Ps of service design for holistic design: people, products, partners, products, and processes. On the other hand, if we talk about four ps of 4 dimensions of service management in ITIL4, it has the following management approaches.
- Organization and people
- Information and technology
- Partners and suppliers
- Value stream and processes.
These are some significant differences between ITIL4 updated versions of ITIL and ITIL3. These are the differences that you have to keep in mind while applying for ITIL certification. Both frameworks have their own importance and values in the industry, and we can’t deny them at all. ITIL4 has a brighter future in the ITSM framework. It will make this framework more dynamic and evolving by making some changes to information and technology.
