ITIL is a globally recognised best practice methodology for IT service management that is used all over the world by leading organisations. ITIL ensures that their IT services are aligned to the needs of their business. ITIL provides trusted guidance on how businesses can use their IT services to support their goals and facilitate business growth.

ITIL is backed by an official range of certifications that provide knowledge of service management best practice and guidance on how to apply this knowledge across the IT service lifecycle. The range of certifications starts with ITIL Foundation, which provides entry-level knowledge of the principles of ITIL, and progress to ITIL Expert, further demonstrating knowledge of the whole IT service lifecycle.
