Communication Channel

  In your project, you have conducted a communication requirements analysis to determine the total number of possible communication channels in the project. While conducting the analysis, you learn that the number of communication channels:

 
  Choice 1 Increases in direct proportion to the number of people
 
  Choice 2 Decreases in inverse proportion to the number of people
 
  Choice 3 Increases in exponential proportion when the number of people increases
 
  Choice 4 Depends on the type of project

 4

last line p253,also potential and actual - complete para

also article 1.8, and 4.3

 According to the formula it shows that for every person added you would find the number of communication channels increasing by multiples.

 

So I would chose choice 3 as the question merely asks what you learn about communication channels in general and is not specific as the nature of the project.

It should be depending on type of project. 

it increases with exponential proportion

 

answer 4 is wrong because you always have to consider all stakeholders

 The number of communication channels increases exponentially
 as the number of people increases
