ESB标书的评估 （1）

在过滤了几个离谱的标书（价钱离谱，付款要求离谱，本地项目参考不足）后，
剩下不到一个手的数目供应商分别基于SAP,Oracle,SoftwareAG,Biztalk,Tibco.

每个供应商都愿意给我们做poc(概念验证)。但是以每个供应商2个星期为例，想在四月开始发出合同，应该很难。

只好发出以下的想定场景，要求供应商提供演示video.

Scenario : 
A front-end XXX web application passing in customer ID as a parameter to a web service which aggregates information from
- a web service from a lease management system, which provides lease-related information such as lease expiry date of a particular customer
- a BAPI call to a SAP ERP system, which provides customer payment history

演示video要求

- development/configuration involved in linking up to the SAP system and lease management system
- development/configuration of the web service which aggregates information from the lease management system and SAP system
- configuration of security feature such as who is authorized to consume the web service
- deployment of the services to production environment
- maintaining/troubleshooting these services in production, e.g. finding out the status of each web service call, the content of messages passed, timestamp. 

看看那一个方案在开发，部署，管理，维护上有优势。

苹果和苹果比较，算公平了。
