1.  Draw a "sociogram," a diagram that shows who talks to whom at least once per week.  To create the sociogram, array the names spatially, drawing a line between each pair of people who talk to each other at least once per week.  To give you a start, here are the links for Eduardo:

 
 
 
 
 
 
2.  Based on your sociogram, try to identify which persons, if any, probably function within this organization as:

• isolates:
• opinion leaders:
• gatekeepers:
• cosmopolites:
• bridges:
• liaisons:

But this sociogram does not really explain the centrality of each person in the network. To assess centrality, you can follow a simple mathematical procedure.

 4.  First, identify the two-step links that connect one individual to another. There is a
two-step link between two persons if you can get to the person through the network by
going through another person.  For example, there is one two-step link connecting
Tyrone to Paul through Leland. Enter the number of two-steps links connecting
each individual to each other individual into the matrix. For any pair in this network,
there will be zero, one, two or three of these two-step links.  Note that the matrix
is symmetrical.

Then, total at the bottom of each column the total number of two-step links found for each individual. The person with the largest total is the most central in the network. Rank each person from "most central" to "least central".

 
 
 
 
5.  You have also been given the following organization chart. Who has the "most important contacts?  (Hint: superimpose your network links onto the organization chart.)

Finally, you note the office floor plan. The office has modular, adjustable walls.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 7.  Now that you have analyzed some facets of this group's communication patterns,what recommendations would you make to improve communication within this organization?  Is there anything else that you would like to find out?
