You are the program manager for your program and are creating a communications management plan. Management wants you to address the type of communications based on the number of communication channels

The correct answer is B. 15,351. This question tests the ability to calculate the net increase in communication channels when stakeholder count grows, using the formula n(n-1)/2 for each count and finding the difference.

Program Communications Management

Question

You are the program manager for your program and are creating a communications management plan. Management wants you to address the type of communications based on the number of communication channels you'll have within the program.

Why each option

This question tests the ability to calculate the net increase in communication channels when stakeholder count grows, using the formula n(n-1)/2 for each count and finding the difference.

A59,340

59,340 is the current total number of communication channels with 345 stakeholders, not the difference between the two stakeholder counts.

B15,351Correct

With 345 stakeholders, channels = 345x344/2 = 59,340; with 387 stakeholders, channels = 387x386/2 = 74,691; the difference is 74,691 - 59,340 = 15,351, which represents the additional communication complexity added next week.

C861

861 is the number of channels among only the 42 net-new stakeholders in isolation (42x41/2), which ignores the interaction of new stakeholders with all existing ones.

D74,691

74,691 is the total number of channels with 387 stakeholders, not the incremental increase over the current channel count.
