Hello,
Concision is integral to effective communication. It can be very difficult to understand a person's point of view, or instructions, if the message is not delivered in a clear and concise way.
To be concise means to say everything that is needed to be said, in the shortest and most efficient way possible. In order to learn how to be more concise when communicating, it would be a good idea to first expand one's vocabulary. This will allow you to use the correct words that suffice to say what is needed to be said in one word instead of a whole sentence.
Following this, it is also useful to develop exceptional interpersonal skills. Knowing how to communicate with others is imperative to delivering a message accurately. This involves knowing when to speak and when to be silent, and learning how much to say. If you are really looking to hone in on your point, it is advised to try bullet pointing, which makes things very clear.
Doing these things will certainly ensure much more concise communication. I hope this helps.
