A Change is defined as the addition, modification or removing of something that could have an influence on IT Services. The scope ought to consist of products this kind of as IT expert services, elements that is applied to guidance or supply the solutions, procedures and documentation.
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. The Taxi is generally consulted for considerable change that have a wide or key affect to the organisation.

In summary, a Taxi or ECAB’s key purpose is an advisory just one, which is to guidance and aid the Change Authority in earning to final decision as to whether or not a ask for for change ought to be accredited or rejected. The Taxi or ECAB does not authorise a Change unless they are particularly supplied the function as a Change Authority as very well.
