內容簡介
本書結合 IT項目的特點,通過細化、量化、圖形化的方法全面解讀 IT項目管理領域的量化管理實踐方法。
本書上篇為量化管理的方法篇,下篇為量化管理的套用篇。方法篇包含第 1~11章的內容,系統地介紹了“細化、量化、圖形化”的量化管理體系,對每類細化方法、量化方法和圖形化方法均輔以相應的 IT項目管理領域實例進行說明。
套用篇由第 12~18章的內容組成,描述了量化管理方法在 IT項目管理主要領域的典型套用,這些領域包括 IT項目管理可行性分析、需求管理、進度管理、成本管理、質量管理、人員管理和風險管理 7個領域。讀者對這些典型方法稍加修改、甚至不加修改就可以套用到 IT項目的管理實踐中。
本書的讀者對象主要為 IT行業的項目經理和管理人員,亦可供高等學校項目管理專業、計算機專業、軟體工程專業等相關學科的本科生、研究生作為學習 IT項目管理的教材和教輔之用。
