总共五分钟的presentation时间，其实考察的真不只是case本身。常用的presentation步骤走一遍，基本上需要两分钟，其余有关case的信息，最好通过一个图，四个象限，优劣势一分析，时间就过去了。
一般的presentation我想应该是这样的流程：
1，Good morning(Or afternoon), and self introduction.
2, Presentation topic, objective.
3, Presentation 将分几个部份，agenda是什么。
4，"If you have some questions, please feel free to interrupt me....."
5，Let's go to the first parts.....
6，Second, ......
7，Finally，......
8，In sum, (or in conclusion) ......
9，Ending. |
