The concept of IT Infrastructure Library (ITIL) can into existence in the 1980s when the government of the UK undertook an initiative to revamp the IT practices followed at the workplaces. Not long after, ITIL certifications became one of the most sought after certifications for professionals involved in IT Service Management (ITSM) throughout the world. Peoplecert conducts the ITIL certification examination worldwide, on the behalf of Axelos Limited, and the best of the ITIL certifications is that it never expires. The main focus of ITIL is to teach the best practices and guidelines to create and improve an ITSM process.
ITIL practices not only help to adapt to the existing IT infrastructure but also offers room for growth, hence making the infrastructure sustainable over time. It takes into account the current practices and management processes and provides guidelines to make it better. It helps an organisation to improve its customer relationships, to reduce the present risks, establish cost-effective practices, and stabilises the IT environment for growth. ITIL has been successful for more than 30 years because it is vendor-neutral and non-prescriptive. It is not based on a specific business model, but the combined experience of several IT professionals. Its main strengths are its versatility, flexibility, and scalability.
In February 2019, Axelos introduced ITIL 4 as the latest edition of ITIL certifications to replace the existing ITIL v3. It offers four levels of expertise – foundation, ITIL 4 managing professional, ITIL 4 strategic leader, and master. ITIL 4 offers a more integrated approach by integrating other popular ITSM platforms like lean, agile, and DevOps, and the central point of focus in this is the customer, around whom the entire process is modelled. The working of the various elements of an organisation is based on the service value system (SVS) defined in the ITIL 4 coursework. By successfully undertaking ITIL courses you can better understand the need of your customers and hence offer better services to them. This not only helps in maintaining better customer relations but also helps beat the competition from rival organisations. It also guides the professionals to better understand the ways to improve the services offered. ITIL also helps in greater collaboration between the IT and the other aspects of the business. It also helps streamline the risk management by identifying the problems and reducing service failures. Through its seven guiding principles and four dimensions, ITIL enables the professionals to design, implement, and troubleshoot the IT services offered.
