5、b规那么粗略估算出人员规模：每并发用户所需五人月。资料来源：Gartner 集团的丈量基准数据。备注：ESP为企业效力提供商。例如国际六大咨询效力商。 There is no correct size for an ERP implementation team, there are simplytoo many variables involved. However, having said that some data is betterthan none. Using twelve selected Gartner Measurement SAP benchmarks, thevaria

6、bility in staffing quickly becomes apparent. Core implementation teamsizes 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 number of

7、interfaces. However, looking back at the implementation usingoperational concurrent users as a metric, a correlation was found. Acoarse rule of thumb is 5 person months per concurrent user. Estimationsof project duration and concurrent users would lead to an overall estimatefor staff size. A rough a

8、pproximation for concurrent users would be 1:6named users.对于一个ERP系统实施团队的大小而言，没有规范答案，由于在实践情况中涉及太多不定要素。有人说有数据总比没有的好。援用十二组Gartner公司的丈量SAP实施基准数据为例，基中人员配备可变要素变得明显。根据SAP以往工程实施时间的情况看，其中心实施队伍规模普通从24人到161人，实施时间范围从10个月到48个月。在数据中没有反映明显意义的相关性，例如产品的模块数、方案实例数、客户化程度或接口等。但是，运用并发用户的丈量规范来回想工程的实施，就可以发现它们的相关性。单凭此阅历粗略估算

9、，每并发用户需五人月，估计工程继续的时间和并发用户有可以估计工程组的大小规模，一个粗略的近似数是：每并发用户：命名用户=1：6For the 8 staff roles measured, the data indicates a wide range of usage,with configuration dominating share of staff. Approximately half the casesused ESP for certain roles and when they did the averages indicatedsignificant portions of

Many companies draw from thesame pool of SAP-skilled resources for both implementation and support.运用软件支持任务人员能处置有关软件运用用户问题，例如：初级入门、错误修复。、报告的编写和

14、运用软件功能问题的反映。许多公司从SAP熟练的阅历中获得实施和支持方面的协助 。Infrastructure staffing includes technical services personnel such as the Basissupport team, systems programmers, capacity planners and performanceexperts. Also included are operations staff such as console operators, jobschedulers and tape operators. We see n

15、o great difference in infrastructurestaffing between SAP implementations and other client/server environmentswhen we look at common metrics such as support headcount per unit ofcapacity.根底运用人员有技术效力人员，例如技术支持小组、系统程序员、消费量方案员、执行专家等。同时亦包括相关操作人员，例如控制台操作员，任务日程方案员、数据备份员。当我们回想其共同机制、规范如每容量单位的支持人员时，我们发如今SAP实施和

16、其他客户/效力环境之间的根本运用人员并没太多的不同。Two rules of thumb emerge from the selected benchmark data. Total EFT forapplication support is correlated to concurrent users, similar to what wasdone earlier for implementation. Infrastructure support is better correlatedto server capacity since this measures infrastructu
