This is all well and good, but you will still benefit greatly from simply being able to deliver a moving speech, or being able to communicate what people need to do.
Communication is particularly important because it is what will prevent avoidable mistakes. If you are not able to communicate what needs to be done or why, then people will set about completing the wrong task, and with the best will in the world, there will be mistakes.
