An important persuasive tactic to be used for written communication is writing front$-$loaded messages. A message is said to be front$-$loaded when key ideas are placed in the beginning of the message. Front$-$loaded messages are particularly important for leaders because

technical terminologies are extensively used

the passive voice is used to compose the message

people expect leaders to be powerful communicators

the message is extensively backed by data

In communication, making one's point quickly would give power and authority to the message sender$.$ A leader can be a highly effective communicator if he frequently qualifies his statements with disclaimers

has clarified the idea in his mind and knows what he wants to communicate

uses vocal pauses to extend the length of his speech

emphasizes indirect talk and apologizes repeatedly
