ITIL V3 角色的定义
Roles within ITIL V3 Roles are employed in order to define responsibilities. In particular, they are used to assign Process Owners to the various ITIL V3 processes, and to illustrate responsibilities for the single activities within the detailed process descriptions (EPCs). The definitions found here (in alphabetical order) are meant to be short, summing up the main characteristics of a specific ITIL V3 role.
