1.       You are managing a telecom project. You have got two teams reporting to you. One team is responsible for equipment installation and the other team is responsible to commission and test that equipment. Both teams are working in parallel such that as soon as the installation teams finishes equipment installation at one site they move on to another site for installations and the commissioning and testing team start their activities on the newly installed site. The reporting structure is such that each of the teams has 5 engineers headed by a team lead. Each team member interacts with each other; however only the team leads interact with you. Both the team leads also interact with each other to synchronize their operations.

How many communication channels do you have in your project?

A.       33

B.       23

C.       42

D.       78

You are right:

For  Team 1&2: No of Member = 5+1 = 6

No of Comm channels = 6*5/2 = 15

Team Lead + PM = 2 TL +1 PM = 3

No of Comm Channel = 3*2/2 = 3

Total Comm Channel = 3+15+15 = 33

Please note: "Each team member interacts with each other "

So, can we add 10*9/2 = 45 to earlier 33, which sums up  to 78.

Any thoughts?

Rahul.
