IT郵件系統建置用運專案管理手法之必要性當我們要建立一個郵件資訊系統也就是我們通稱的Mail server,用專案管理的手法來建造郵件系統可以大幅降低建置過程的風險。
郵件系統軟硬體的建置過程中,建置步驟中有很多的前後相依性,也就是PMBOK中” Dependency Determination ”當中的”Mandatory dependencies”(強制依存關係),硬體建置完成之後,必須先確認硬體架構是否正確,接下來再安裝作業系統,資料庫等等…。我們曾經遇過郵件系統安裝完成之後,郵件系統不穩定,用診斷工具偵測無法發現正確的問題點,細部追查之後發現在郵件系統的軟體安裝完畢,工程師才發現有硬體遺漏安裝,因此又加裝了硬體,此時,資料庫以及其他軟體已經安裝設定完成,工程師忘了再去逐步修改,導致日後問題不斷。
當一家公司的郵件系統不穩定時,狀況嚴重會造成客戶信件的遺失,進而導致訂單流失。如果郵件系統建置專案一開始就採用專案管理手法來建置,就可以大幅降低專案執行過程沒有按照前後相依性執行專案而導致系統不穩定的狀況。
因此,確定依賴關係對建置一個郵件資訊系統而言相當的重要,專案開始前便將所有的強制性依存關係(Mandatory dependencies)、可斟酌處理的依賴關係(Discretionary dependencies)、外部依存關係(External dependencies),作縝密的規劃。當中還要加入時間提前量(Leads)與時間滯後量(Lags)來確保專案執行過程的順暢度及降低風險,例如:約定硬體裝機的前一天,工程師必須跟客戶確認電力設備以及網路設備是否已經完成,才不會發生所有設備已經運送到客戶端無法安裝的窘境。
一個郵件系統專案有很多細項,細小而繁雜的項目如果沒有很清楚的轉達給所有專案團隊,很容易被忽略,很多專案經理因此延後了驗收日期,造成客戶滿意度下降,WBS分解結構可以協助專案經理更縝密的掌控所有該執行的可交付成果,用專案管理手法來建置郵件系統,可以降低風險,又可以讓所有的專案團隊很清楚的知道哪一天要做哪一些事,所有的工程細才能做的確實。大幅提升IT專案管理的品質!

criminal activity
Project management is the application of knowledge, skills, tools and technologies to project activities in order to meet project requirements. These include initiating, planning, executing, controlling and closing the project. These skills can also be applied to resolving criminal activity.
When criminal activity occurs police officers should investigate as soon as possible. In U.S.A for example, there are three stages in criminal investigations: on scene arrest, hot search and warm search. In Taiwan for example, governments establish policies to deter kidnappers. If kidnap occurs, police officers are allocated to a specific task force to solve the crime.
Recently, it was a miracle that Jaycee Duggard who was kidnapped when she was 11 years old was found after 18 years. Jaycee’s step father witnessed the abduction which took place as his daughter was preparing to board a school bus. His step daughter was force by a married couple into their vehicle. The step father attempted to chase the car as it sped off but was unsuccessful as he was riding a bicycle. He phoned 911 and reported the situation to the police and a search for the missing girl was commenced. The case remained unsolved for the next 18 years during which time the abducted girl’s parents were divorced. Not only was the girl traumatized by the event and the subsequent years for inability of the police officers to solve this horrific crime. (Sydney morning herald and Canberra time 29/08/09 page1)
Project management is a useful method and is wisely applied to many diverse projects such as National aeronautics and space administration (NASA)’s lunar project and Olympic Beijing’s project. If governments allocated greater financial resources to investigative bodies to gather experts including psychologists, police officers, forensic and IT specialist to work in a project management team, it could bring more cases to a favorable conclusion.
