您需要多少人來支持sap項目

1、附件三：您需要多少人來支持SAP項目？眾所周知，實施R/3 費用很高，但是長期支持費用有多少？請用下文中 Gartner的 "rules of thumb"來算一下，如果采用SAP系統(tǒng)你需要多少人來支持？與您原來估算的差距有多大？同高昂的長期支持費用相比，初期實施費用根本算不了什么！原文：" Managing Enterprise Applications: From Packages To Productivity ", Gartner Group Europe Symposium proceedings, Cannes, France, Novemb

However, having said that some data is better than none. Using twelve selected Gartner Measurement SAP benchmarks

6、, the variability in staffing quickly becomes apparent. Core implementation team sizes ranged from 24 to 161 with implementation elapsed times ranging from10 to 48 months. No obvious meaningful correlation was present in the data, e.g.number of modules, number of instances, degree of customizationor

A rough approximation for concurrent users would be 1:6named users.對于一個ERP 系統(tǒng)實施團隊的大小而言，沒有標準答案，因為在實際情況中涉及太多不定因素。有人說有數(shù)據(jù)總比沒有的好。引用十二組Gartner 公司的測量SAP 實施基準數(shù)據(jù)為例，基中人員配備可變因素變得明顯。根據(jù)SAP 以往項目實施時間的情況看，其核心實施隊伍規(guī)模一般從24 人到 161 人，實施時間范圍從10 個月到 48 個月。在數(shù)據(jù)中沒有反映明顯意義的相關性，例如產(chǎn)品的模塊數(shù)、方案實例數(shù)、客戶化程度或接口等。但是，運用并發(fā)用戶的測
