Although ITIL was originally defined in the UK, ITIL is becoming the defacto global standard for ITSM and has strong support in the US, Europe, Asia and Australia. The ITIL framework doesn't outline specific steps that businesses must follow, but it shares with IT professionals best practices that they can customize to their organizations. What is now called ITIL version 1, developed under the auspices of the CCTA, was titled "Government Information Technology Infrastructure Management Methodology" (GITMM) and over several years eventually expanded to 31 volumes in a project initially directed by Peter Skinner and John Stewart at the CCTA.
