The Information Technology Infrastructure Library, better known as ITIL, is the pre-eminent framework for managing IT service delivery around the world. ITIL defines a service lifecycle model that prescribes specific processes and activities during the design, development, delivery, and support of IT services. For the purposes of this discussion, IT services are any IT activities that deliver business value to a company's end users, customers and other internal or external stakeholders. Examples of IT services include centralized corporate email and corporate websites based on back-end IT processes, such as server and network administration. The current version of ITIL is known as ITIL V3.

The ‘Information Technology Infrastructure Library’ is a set of best practices for creating and improving an ITSM process. It is designed to help businesses manage risks, strengthen customer relations, establish cost-effective practices and build stable IT environments for growth, scale and change. In short, an ITIL Practitioner is an expert in continually shaping IT service development processes.
ICT deployment provides a framework for the successful management of design, build, test and roll-out (deploy) projects within an overall ICT programme. It includes many project management disciplines in common with PRINCE2, but has a broader focus to include the necessary integration of release management and both functional and non functional testing.
ITIL isn’t going anywhere and there are many advantages to completing your certification in any of ITIL’s five mastery courses. While there is plenty to learn on-the-job, getting a head-start on the foundations, terminology, strategies and lifecycle stages will be a big help to you getting hired for the job role you want and will help you succeed within the organization.

Organizations and management systems cannot claim certification as "ITIL-compliant". An organization that has implemented ITIL guidance in IT Service Management (ITSM), may be able to achieve compliance with and seek certification under ISO/IEC 20000. However, while relatively closely aligned, ISO/IEC 20000 and ITIL Version 2 do not define identical processes.[59] This gap has become much wider with ITIL versions 2007 and 2011. ITIL now defines twice as many ITSM processes as ISO/IEC 20000 (26 compared to 13),[60] but there are also more subtle differences, for example:[61]
In fact, IT has become a mission-critical service delivery mechanism for companies that rely on complex computing resources to keep their businesses operating and generating revenue. ITIL allows companies to define and implement a documented, repeatable process that assists them in staying focused on the large and small details involved in rolling out new IT services and managing those services afterward.

ITIL certification is split into five stages, namely foundation, practitioner, intermediate, expert and master levels. Each of these levels has different requirements for appearing, clearing and is awarded a specific set of credits. For instance, one needs to have a total of 22 credits to be certified as an expert. Apart from these, there are complementary certifications that help you reach the expert level faster. Here’s an overview of the various levels and credits. 
One of the best things about taking advantage of the ITIL training offered by Cybrary is that you have the ability to complete all of the training lessons online. So long are the days of having to search for classes near your home. You no longer have to spend your evenings or weekends sitting in a classroom, losing precious time that could be spent with your family and friends. Cybrary gives you the freedom to complete the lessons whenever and wherever is most convenient for you.
ITIL has been deeply entrenched into the fabric of enterprise IT for some time now, and despite the nascent contrarian opinion every now and then, it’s safe to assume that the framework’s popularity isn’t going to diminish any time soon. In fact, AXELOS is constantly changing and updating their certification courses in order to keep up with the times and shape ITIL’s commonly established principles to govern today’s modern technology and development trends. That said, becoming ITIL certified is a safe bet to stay prepared for the future, and the demand for educated ITIL experts in the fields of incident management, service management, change management and other ITSM related areas are still very high in 2017.

The IT Infrastructure Library® (ITIL®) is the world's most adopted and widely-recognised approach to IT Service Management (ITSM). ITIL training exists to support the needs of a business environment. It enables you to reduce your IT costs while delivering better services, by improving the way teams interact and manage your business' IT infrastructure. Used and adapted by industry-leading brands such as Hewlett-Packard, IBM, NASA, British Airways and The Walt Disney Company, studying ITIL can provide many proven benefits.

Taking this strategy on board offers a number of advantages for businesses. Perhaps most notably, it can cut back on the amount of time and money that gets wasted throughout the service development lifecycle, while also raising the quality of the end-product. This, in turn, can provide a huge boost to customer satisfaction once a service or product is implemented, as well as the morale of staff working on it.
In July 2013, ownership of ITIL was transferred to AXELOS, which maintains the ITIL framework and accredits training and examination institutes. Hundreds of ITIL Accredited Training Organizations (ATOs) are available to deliver training, and ITIL certification exams are administered at the end of a training course or by an Examination Institute (EI), many of which work directly with the ATOs.
A summary of changes has been published by the UK Government. In line with the 2007 edition, the 2011 edition consists of five core publications – Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. ITIL 2011 is an update to the ITIL framework that addresses significant additional guidance with the definition of formal processes which were previously implied but not identified, as well as correction of errors and inconsistencies.
ITIL® Foundation has no prerequisite, but every certification afterwards does. ITIL® Practitioner and the ITIL® Intermediates have a prerequisite of ITIL® Foundation. Those taking the ITIL® MALC exam must hold ITIL® Foundation certification and have gained 17 credits throughout the ITIL® scheme by studying ITIL® Foundation and a selection of ITIL® Intermediate qualifications.
The new ITIL 4 Foundation which is an update from ITIL v3/2011 was launched on 18 February 2019. ITIL 4 is a new certification scheme that will slowly replace the existing scheme it is based on the transformation to a digital environment. It is designed to offer a clearer career path for professionals from Foundation to higher levels. There is no Bridge exam for current ITIL Foundation holders to ITIL 4 Foundation. Candidates who hold the current ITIL Foundation will need to take the ITIL 4 Foundation to be certified in the new scheme or they would need to accumulate 17 ITIL v3 credits and then take the transition module.
All said and done, you will have a better chance of catching an employers attention if you have an ITIL certification. In fact, ITIL certification is used as a basic filter by many employers to weed out candidates. But does that guarantee you a job? Probably not. A good experience, backed by a stellar demonstration of skills gained via certification is going to better equip you for the challenges your work life throws at you. Echoing the same statement, Stuart Rance of Optimal service management adds that
The Service Design (SD) volume[23] provides good-practice guidance on the design of IT services, processes, and other aspects of the service management effort. Significantly, design within ITIL is understood to encompass all elements relevant to technology service delivery, rather than focusing solely on design of the technology itself. As such, service design addresses how a planned service solution interacts with the larger business and technical environments, service management systems required to support the service, processes which interact with the service, technology, and architecture required to support the service, and the supply chain required to support the planned service. Within ITIL, design work for an IT service is aggregated into a single Service Design Package (SDP). Service design packages, along with other information about services, are managed within the service catalogues.
The good news about ITIL certification is that it is a valuable skill for almost any IT professional, from system administrators to chief information officers (CIOs). Many large companies have dedicated ITIL coaches or mentors who help shepherd projects through the various steps of the ITIL framework. These ITIL gurus have a wide understanding of the IT landscape and can usually spot trouble with a service design document or implementation plan in a matter of minutes.

By adopting the ITIL framework, companies ensure that their services are delivered according to a set of consistent, well-defined processes that incorporate best practices and processes, resulting in a predictable level of service for users. The benefits of ITIL include reduced cost of service development and deployment, improved customer satisfaction with service delivery, increased productivity from IT personnel, quality improvements, better management metrics of services and increased flexibility in adapting services to changing business requirements.


To enable candidates to meet their own career goals, AXELOS lets you achieve qualification in one category or by choosing modules from both categories. AXELOS recommends that you have at least two years of IT service management experience. Note that you must complete your Intermediate exam preparation by completing a training course offered by an accredited training organization (ATO), i.e., you cannot self-study then sit for the Intermediate exam.
