You are project manager leading a US $4000000 mechanical engineering project．To date，you’ve been leading the other 11 people who comprise the overall project team．Lately you’ve noticed that you are spread too thin and the schedule is being negatively impacted．Because the project is date constrained，you convinced senior management to accept a cost variance and add a senior quality assurance analyst to the project team．This new resource will work directly with the three project team members who comprise the testing subteam．How many more communication channels will there be on the project team
A．12．
B．11．
C．78．
D．66．
参考答案：A
解析： 你是项目经理，正在领导一个4000000美元的机械工程项目。迄今为止，你领导了其他11人，共同组成了这个团队。最近，你接到通知说以前的进度表被压缩，因为这个项目是时间限制型，你说服高级管理层接受了成本变更并补充了一名高级质量保证分析人员到这个项目团队。这个新人将直接与三个项目团队成员共同组成测试子团队。则项目团队中多了多少条沟通渠道 A) 12。 B) 11。 C) 78。D) 66。 最初成员数量为12人，沟通渠道为12×11/2=66条；后来添加了1个，沟通渠道为12×13/2=78条。增加的渠道数目为78-66=12条。
