在前一篇文章中已經簡單的介紹了ITIL V2的Service Delivery 的5個管理部分，接下來我將接著介紹Service Support所提到的5個管理流程與服務櫃台的運作，在Service Support中共包含了事件管理、問題管理、異動管理、結構(組態)管理及發布管理5項管理規範。

ITIL V2據說在今年將走入歷史，將轉由ITIL V3完全的取代，但是基本論述都還是以ITSM為基礎，只是將ITIL V2的10項管理流程轉換成ITIL V3的四個週期包含Service Strategy、Service Design、Service Transition、Service Operation，ITIL網頁上也有介紹更詳細的轉換對應標準，有興趣更深入了解或導入ITIL的IT管理人員可以參考下列網頁
