    Everything You Need To Know About  ITIL®

    What is ITIL®?

    Today, the worlds of business and technology have overlapped each other and are linked inextricably. To thrive and to remain competitive, companies need to bring IT services in considerable focus. The transition of a company’s objectives and capabilities to IT can be an overwhelming process. To ease this transition and to select, plan, deliver and maintain a certain standard in IT services within the organisation, a standardised framework called the Information Technology Infrastructure Library (ITIL®) is designed.

    The ITIL® ensures that the implementation of IT services for any business has efficiency and predictable service deliverability at its core. The framework makes sure that the IT services department in any organisation is an active business partner and not just a backend service provider.  

    The reason why ITIL® is gaining such importance and focus in the business world is that without it, the resources spent on designing and developing an IT service management (ITSM) process would be futile, which would, in turn, make the business less competitive, susceptible to losses in money and customers and less efficient.

    ITIL® History

    The growing discrepancies in processes, deployments and inconsistent IT services on account of the geographical decentralisation of data centers in the 1980s led to the need for ITIL®.

    Released as a series of books in 1989 by The United Kingdom's Central Computer and Telecommunications Agency (CCTA), ITIL® Version one, i.e., ITIL® V1 was their response to a need to recognise IT as an essential service and the need to apply it consistently across the organisation.

    ITIL® consists of various levels and modules. It aims to cover comprehensively everything from service strategies to continuous improvement which would ultimately help practitioners to adopt the IT services for their organisation and be prepared for changes down the line.

    ITIL® Updates

    Post-1989, the ITIL® has been upgraded to reflect the changes in the business world and is now a highly renowned and recommended practice with multiple thousands of practitioners getting certified and implementing it.

    Post launch, the first major change in ITIL® came in 2000-2001 with the release of ITIL® V2. This version focused on making the entire framework more accessible and less formidable for the candidates. It compiled the entire framework into nine sets of related elements. This version was followed by the ITIL® V3 in 2007 which was a compact and well-designed framework of 26 functions that were combined into five volumes.  This version was built to inculcate the concept of service lifecycle structure. Few changes were introduced to V3 which was launched in 2011 as ITIL® V3 2011. In 2019, the latest version, ITIL® V4, is all set for launch with a focus on the ITIL® service value system and upgrading the credit system.

    ITIL® Publications

    The framework of ITIL® V3 encompasses five core publications which aim to cover the entire lifecycle of ITSM. They are reviewed and updated regularly to reflect the advancements made in IT technology. The five core publications are:

    1. ITIL® Service Strategy: This publication aims to identify and describe the goals of the business and the objectives of the IT services and align them to customer requirements.
    2. ITIL® Service Design: Based on the strategy defined in the previous publication, this publication aims at outlining the IT architecture, policies, and procedure as well as documentation.
    3. ITIL® Service Transition: This is an important publication which focuses on the change management and practices to be followed for releasing each policy/service change. It mainly aims to guide the transition and anticipated interruptions.
    4. ITIL® Service Operation: This is the actual working, functioning and operating manual in the ITIL® framework. The operation help in managing IT services regularly.
    5. ITIL® Continual Service Improvement: This publication is futurist in its outlook as it aims to guide the organisation through improvements and updates within the ITIL® framework.  

    As is evident, the modules cover everything from the beginning, i.e., identifying the customer’s needs to designing and implementation and in the end, monitoring and improving the ITSM process.

    ITIL® Modules 

    The entire ITIL® process is a module based framework. The certification, for example, under ITIL® v4 has been broken down into ITIL® Foundation and the ITIL® Master exams. Post the ITIL® Foundation, the course is further split into two modules: ITIL® Managing Professional (MP) and ITIL® Strategic Leader (SL), which the candidate need to complete in order to progress further.  

    ITIL® MP has the following modules:

    • ITIL® Specialist – Create, Deliver and Support
    • ITIL® Specialist – Drive Stakeholder Value
    • ITIL® Specialist – High Velocity IT
    • ITIL® Strategist – Direct, Plan & Improve

    ITIL® SL, on the other hand, has the following modules:

    • ITIL® Strategist – Direct, Plan & Improve
    • ITIL® Leader – Digital & IT Strategy

    Nine ITIL® Principles & ITIL® Modules

    Nine ITIL® Principles & ITIL® Modules

    Released in 2019, ITIL® V4 has the same focus as its predecessors. Although, it does have an updated framework which also represents and accommodates modern technologies and software. The program has illustrated nine guiding principles with an aim to provide for change management within an organisation, organisation communication, measurement, and metrics. These nine principles include:

    • Focus on value

    Here, ITIL® encourages the professional to define the service output in a manner that captures the needs of the customer.

    • Design for experience

    The paramount thing here, as per ITIL®, is to understand the context within which the service offered will be consumed by the customers.

    • Start where you are

    This principle pushes the candidate to collect information and understand the customer’s current pattern of consumption and how the services offered under ITIL® will support it.

    • Work holistically

    By understanding the entire value chain of the customer, ITIL® ensures that the services offered do not disrupt that value chain but make an active contribution to it.

    • Progress iteratively

    ITIL®, while being implemented, must start with the minimally viable option and then progress from there based on an understanding of the priorities of the customer’s needs and expectations.

    • Observe directly

    ITIL® requires that the customers including users and sponsors are heard out and observed regularly. Candidates must observe how the service is delivered, executed and consumed.

    • Be transparent

    In the realm of ITIL®, sharing is encouraged: of ideas, thoughts, failures, concerns as well as improvements made.

    • Collaborate

    ITIL® requires the active involvement of all stakeholders from customers, users to suppliers.

    • Keep it simple

    It is imperative that any implementation of ITIL® uses simple words which are easy to understand to ensure clear communication.

    ITIL® principles and modules when systematically followed can help an organisation manage as well as mitigate risks better, save on IT support costs, create a thriving ecosystem which ensures growth, scale, change and strengthens the organisation’s relationship with their end users i.e the customers.

Many IT professionals in the industry consider the ITIL® certifications as the Holy Bible to IT support. ITIL® V3 utilises a credit system for all its levels from the Foundation through Master levels. Each certification level earns a certain number of credits. After obtaining the requisite number of credits, the individual will take the ITIL® Master certification. In ITIL® V3, a total of 22 credits are required by a professional, if they are to earn the ITIL® Expert certification. The benefits of the ITIL® certification program include:

    How much does ITIL® certification cost?

    Currently, ITIL® certifications are under Axelos. An individual can start the course by either using a hardcopy, PDF, ePublication or via an online subscription which can be availed directly from Axelos. While this is the primary cost, the second is the training cost. For each level of the course, there is a different cost associated. The curriculum leading to the initial certificate usually runs for two days and the courses commencing to higher certifications can run for a week or more.

    There is an additional cost of re-engineering a few of the processes to enable ITIL® frameworks and enable them to comply with ITIL® guidelines. An additional cost would be the investment in the ITIL® study guide and ITIL® practice exam which is set to be between $30 to $50 respectively. Therefore, there is no fixed cost for gaining the ITIL® certification. Axelos has tied up with an institution called  Accredited Training Organisation (ATO) where one can take ITIL® training.

    What are ITIL® complementary certifications?

    Axelos, apart from the five levels of ITIL® certifications, also offers complementary courses under the ITIL® credit system which are known as ITIL® complementary certifications. A total of 6 credits can be earned through these additional courses. It is critical to ensure that there is no overlap between the modules at different levels, as the percentage of overlap that Axelos segregates can be divided into three categories: low, moderate and high. The candidate should focus on staying in the ‘low overlap’ zone to ensure that they earn the right credits. Axelos details the course on its website and gives a hawk-eye view of its benefit.

    Who should do ITIL® certification?

    ITIL® certification is acquired via classroom study and virtual IT coaching which can be supplemented with self-study. An ITIL® certification represents that the person who has it has the requisite knowledge and skills related to ITIL® structure and terminology. It also describes that he has a working knowledge of the core principles and subject areas relating to IT, which is the primary use of ITIL® technology in the management of business services. The certification is helpful for:

    • People who have the basic knowledge of ITIL® and wish to utilise it towards ensuring better control of service operation in a business situation.
    • IT professionals who want positive changes in the efficiency of a business organisation such as cost reduction.

    Following professionals are recommended to take the ITIL® course:

    • IT Managers
    • IT Directors
    • Quality Analysts
    • IT Service Managers
    • Support Professionals and Engineers
    • Service Support Engineers
    • Database Administrators
    • Operations Managers
    • Owners of Business Processes

    What is ITIL® Foundation?

    The foundation course will act as an introduction to ITIL® 4, and it will introduce candidates to ITSM as an end-to-end operating model with a focus on creating, delivering, and improving IT-enabled products and services.

    The certification aims to help:

    • People who require a fundamental understanding of the ITIL® framework.
    • Those who wish to learn how ITIL® can be useful in enhancing the IT service management.
    • IT professionals or others who are working within an organisation that has adopted ITIL®.

    However, the ITIL® V4 foundation certification is helpful to anyone who has an interest in IT service management. ITIL® V4 Foundation candidates, at the end of the certificate course, will have an understanding of the following:

    • A thorough grasp of how to facilitate the co-creation of value for customers as well as other stakeholders via products and services.
    • Exposure to the guiding principles of ITIL® V4.
    • A holistic approach towards the four dimensions of Service Management.
    • Basic terminologies such as Agile, Lean, DevOps and their importance.
    • The significance of ITIL® practices and their value to your business.

    Are there any Versions in ITIL® Foundation?

    ITIL® has seen 4 versions till date. Each of the versions has had the same motive of helping the candidate achieve alignment between the IT systems with the business strategies.

    Version 1 was launched with more than 30 volumes each covering a specific practice within ITSM. It aimed at establishing a model of controlling and managing business operations using IT.

    In the year 2000-2001, in order to make ITIL® more accessible as well as affordable, a new version, ITIL® V2 endeavoured to consolidate the publications into nine sets which focus on logic and were grouped in a manner that matched different aspects of IT management and services.

    Under ITIL® V3, the foundation level was introduced to candidates with the aim of exposing them to the basic concepts, key elements and common terminologies under ITIL®.

    The primary purpose has not changed under the ITIL® V4, and their essential features remain the same. The updated version of ITIL® V4 merely includes advanced material on the additional best practices.  ITIL® V4 aims to address the two major complains of the ITIL® :

    • Its relationship with the ITSM community.
    • Its failure to update itself with the latest trends in IT operations and software development.

    How ITIL® certification helps business?

    ITIL® certification has now become essential for any business which uses digital services daily and aspires to have a flawless ITSM. An ITIL® certification helps with installing good ITSM practices within the organisation. This certification covers the whole development lifecycle of IT, all the way from recognising requirements of IT and business to maintaining and delivering the levels of service in a state of focused review and improvement. This holistic approach enhances the overall customer experience and integration of work.

    To help understand the nuances better, let us explore ITIL® V3 Foundation Vs. ITIL® V4 Foundation.

    ITIL® V3, which is also popularly referred to as ITIL® 2011, was the latest version before the upgrade to ITIL® V4. The new version introduced the process of the Business Relationship Management (BRM) process but other than that, most of the other elements remain the same.  An important change was that it was easier to read and many of the inconsistencies were edited out. ITIL® V4 uses newer techniques to align IT with a more evolved level of efficiency and effectiveness. It is now possible to align ITIL® with other existing methods such as IT4IT, Agile, DevOps, and Lean.

    Even with ITIL® V4, the essential elements of ITIL® V3 remain the same. ITIL® V4 just ensures the inclusion of additional best practices and easier integration.

    ITIL® V4 encourages lesser siloes, more collaboration and encourages communication across the whole organization with the integration of Agile, Lean and DevOps into ITSM strategies. It is made to be more flexible and customizable than ITIL® V3 i.e. more holistic.

    By investing in a training course and implementing ITIL®, you can expect the following things:

    • Enhanced understanding of the customers which aid in delivering better services, long term relationships, and a sound reputation.
    • A developer guide on predicting and reacting to customer service engagement, complaints, and experience.
    • Increased productivity and better management of resources by focusing on the cost-benefit analysis.
    • Risk mitigation and management.
    • Stabilized environment for better alignment of IT and other divisions of your business.
    • Reduced incidences of service failures.
    • A growth in opportunities to network and collaborate with similar business models.
    • Enhanced value of the organisation’s service portfolio.
    • Agile adaptation to new technologies and comply faster to changing needs of the digital world
    • Direct rise in chances of an improved bottom line in your revenue statements.

    Thus, through this, it is clear that ITIL® is almost inevitable for business and must be implemented within organisations who wish to keep evolving with the times and achieve their ever-changing goals with the help of IT.

    To wrap it up, ITIL® is not just a straightforward skills course in IT. It equips the candidate with the requisite resources to apply the knowledge gained to the larger scope of their organization and align with business practices. This means that the candidate would have a practical hold over the best practices, especially when addressing all facets of IT management.
