What do you think is the most important part of communication?

"While I believe it is critical to explain information you are giving someone else in a way that is clear and concise, I think the most important part of communication is listening. It is difficult to have a productive conversation if you aren't sure of the message the other person is trying to convey. Especially in this position, where my job will include designing and modifying material handling systems, it's important to practice active listening and make sure we can identify what the customer actually wants and what designs we can actually provide."
