41、),這些都基于一個(gè)集成的企業(yè)數(shù)據(jù)集。ERP可以為企業(yè)帶來巨大的效率改善,例如,可以縮短訂單和付款的間隔時(shí)間,降低對(duì)后勤員工的需求,降低庫存,以及提高企業(yè)的客戶服務(wù)水平。源于ERP系統(tǒng)的這些作用,世界各地的企業(yè)在過去的十年中,投資在ERP系統(tǒng)上的資金總共約3000億美元(多利安和馬爾科姆,2000)。</p><p> 最吸引許多企業(yè)首席信息官是什么呢,就是通過采用ERP系統(tǒng)后,可以取代以往復(fù)雜的和即將過時(shí)的應(yīng)用
42、程序系統(tǒng),新的系統(tǒng)可以有一個(gè)有信譽(yù)的和穩(wěn)定的供應(yīng)商。比如:韓國(guó)的一個(gè)重要的石油公司,將設(shè)法關(guān)掉已經(jīng)使用了70多年的舊系統(tǒng),并使用新的ERP系統(tǒng)。通過輸入客戶信息和銷售數(shù)據(jù)到ERP系統(tǒng)中,制造商可以生成下一個(gè)周期的需求預(yù)測(cè),進(jìn)而為所需要的原料生成一個(gè)原材料需求信息、生產(chǎn)計(jì)劃、生產(chǎn)時(shí)間表和財(cái)務(wù)預(yù)測(cè),并且密切跟蹤企業(yè)的庫存。</p><p> 隨著采用ERP系統(tǒng)的制造業(yè)公司的數(shù)量不斷地增加,所以有學(xué)者和研究人員對(duì)這方
43、面的研究產(chǎn)生了興趣,他們研究這一技術(shù)的各個(gè)方面,涉及規(guī)劃、實(shí)施、集成、管理和開發(fā)等(李,2000;帕爾和尚克斯,2000;薩姆納,2000)。這些研究案例中,包括:柯里在1996年對(duì)20家英國(guó)公司的ERP應(yīng)用情況研究,杰克庫瑪于1997年對(duì)95個(gè)北美的信息系統(tǒng)進(jìn)行了研究,以及貝森特和海伍德于1999年對(duì)英國(guó)地區(qū)的ERP和其他信息系統(tǒng)的應(yīng)用情況研究。</p><p> 2.ERP系統(tǒng)的選擇過程</p>
44、<p> ERP系統(tǒng)能夠提供普遍的業(yè)務(wù)功能。由于這種普遍性,所以也導(dǎo)致了這樣一種情況,即有些企業(yè)成功了有些則失敗了。因此,建議企業(yè)要有針對(duì)性地選擇適合自己企業(yè)的ERP系統(tǒng)。經(jīng)過研究,我們得出結(jié)論,沒有一個(gè)通用的系統(tǒng)可以適用于所有的公司,而需要有一個(gè)過程去尋找最適合自己的系統(tǒng)。這一過程始于系統(tǒng)安裝項(xiàng)目主管團(tuán)隊(duì),他們必須做好這一步,立足于本企業(yè)的業(yè)務(wù)需求,探索最適合的方案,通過明智的判斷,選擇并應(yīng)用一個(gè)成功的ERP體系。&l
45、t;/p><p> 3.一個(gè)基于成本的業(yè)務(wù)案例方法</p><p> 許多公司發(fā)現(xiàn)ERP系統(tǒng)能夠幫助他們作出更明智的決策。不過還有一些公司則認(rèn)為他們購(gòu)買并應(yīng)用ERP系統(tǒng)主要是基于這樣的一個(gè)理念,即企業(yè)需要這個(gè)而系統(tǒng),而不是從企業(yè)實(shí)際情況出發(fā),來決定是否要采用這一系統(tǒng)。這些企業(yè)斥資數(shù)萬甚至數(shù)億美元的額外成本來安裝這一系統(tǒng)(塞西,1994)。那么,高級(jí)管理人員如何確保他們的公司可以部署ERP系
46、統(tǒng),并構(gòu)建一個(gè)健全的業(yè)務(wù)案例呢?他們能做什么來保證使用系統(tǒng)后能取得成本節(jié)約、流程再造等方面的效果呢?一個(gè)很好的答案是基于成本的業(yè)務(wù)案例方法。</p><p> 采用系統(tǒng)的回報(bào)就是,比如簡(jiǎn)化了操作流程,不需要大批的與員工了,對(duì)訂單需求等預(yù)測(cè)也更簡(jiǎn)單了,但這只是部分好處。軟的回報(bào),如收入或員工生產(chǎn)力的增加等(戈里和莫頓,1971)。在評(píng)估信息系統(tǒng)投資時(shí),這一問題是一種常見的現(xiàn)象(鄧普西,德沃夏克,霍侖,馬克和米漢,
47、1998)。</p><p> 在ERP系統(tǒng)的幫助下,企業(yè)的投資回收期可以縮短,可以更好地將企業(yè)資金更好地用于企業(yè)運(yùn)作中,是企業(yè)更好地對(duì)項(xiàng)目進(jìn)行評(píng)估。ERP系統(tǒng)幫助公司提高收入,或員工的工作效率能得到極大地提高。但部署的難度和費(fèi)用較高,因此企業(yè)采用ERP,應(yīng)該綜合評(píng)估采用這一系統(tǒng),企業(yè)所需付出的成本和收到的效果。</p><p> 4.成功實(shí)施ERP系統(tǒng)的關(guān)鍵因素</p>
48、<p> 4.1案例研究的概述</p><p> 本文選取了五個(gè)企業(yè)組織,本研究初步探討了這些公司選擇ERP系統(tǒng)的目的和過程。選擇這些潛在的研究案例,主要是基于對(duì)這些企業(yè)的各方面的判斷,也就是說,我們也聽取了企業(yè)中全體部門和工作人員的建議,與當(dāng)?shù)仄髽I(yè)的經(jīng)理進(jìn)行了密切的溝通,并參加公司的會(huì)議和研討會(huì),并通過公司的新媒體獲得相關(guān)信息資料。</p><p><b>
