The IT Infrastructure Library (ITIL) is a framework that standardizes selecting, planning, delivering, and maintaining the information technology (IT) services in a business. First developed by the Central Computer and Telecommunications Agency (CCTA) in Great Britain during the 1980s, it has been updated frequently over the years. Currently, it comprises a library of five volumes. Enterprises can use ITIL as a guideline for best practices in their complete IT service lifecycle. This systematic approach is important to businesses that choose to adopt it because it can help them manage risk, strengthen their relationship with customers, establish cost-effective practices, and build an IT stable infrastructure that can grow, scale, and develop over time.

The ITIL 4 Foundation certification is for individuals who want to prove their knowledge of the current version of the IT Infrastructure Library (ITIL). It provides a modular approach to the ITIL framework and consists of a series of qualifications that focus on different aspects of ITIL best practices in detail. The exam also tests your knowledge of the four dimensions of service management, which are organizations and people, information and technology, partners and suppliers, and value streams and processes. There are five different levels of ITIL certification available: Foundation, Practitioner, Intermediate, Expert, and Master. Earning an ITIL 4 Foundation certification at any level will prove your understanding of key concepts of Lean, Agile, and DevOps and how to use them to deliver business value.

The ITIL 4 Foundation certification will maximize career and earning potential in a wide variety of technology sectors. IT project managers must see technology projects through from inception to successful completion, and ITIL gives them a framework of best practices on which to base their processes. Information technology managers supervise a company's infrastructure, including networks, software, data, and security. The ITIL service lifecycle will give IT managers a method of designing strategies that line up with service demand. A service delivery manager creates service-level agreements (SLAs) that break down an enterprise's objectives into projects and day-to-day operations and develops strategies that meet customer and stakeholder expectations. Service delivery is a big part of ITIL. Other careers where the ITIL 4 Foundation certification is beneficial include senior project manager and information technology director.
