Explanation:
Communication channels are paths of communication with stakeholders in a project. The number of communication channels shows the complexity of a project's communication and can be derived through the formula shown below:
Total Number of Communication Channels = n (n-1)/2
where n is the number of stakeholders.
Hence, a project having five stakeholders will have ten communication channels. Putting the value of the number of stakeholders in the formula will provide the number of communication channels.
Hence,
Number of communication channel = (n (n-1)) / 2
= (25 (25-1)) / 2
= (25 x 24) / 2
= 600 / 2
= 300
Incorrect Answers:
A, B, C: These are not valid number of communication channels for the given scenario.
