IT service providers, managed service companies, shared service centres, IT departments, cloud providers, and outsourcing companies seeking to demonstrate structured IT service management.

Frequently asked questions

Common questions

Is ISO 20000 the same as ITIL?

No. ITIL is a best-practice framework; ISO 20000 is a certifiable standard. ISO 20000 certification provides formal third-party verification of IT service management — ITIL practices often support achieving it.
