Individuals new to ITIL will normally assume that the job of the Taxi is to authorise the important or considerable change. Perfectly, indeed and no.
The Change Advisory Board (Taxi) is a strategy described in ITIL V2 and V3’s Change Management method and is a physique that exists to assistance the authorization of change and to aid Change Management in the assessment and prioritization of change.
