In my experience the reason people have such a hard time getting their point across is because they don't understand it very well themselves. Almost no engineers really understand what they are doing so the only effect practicing communication will have is make them better able to hide their ignorance behind fluffy words, kinda like most management types do. I think that it is a good thing when people are bad at hiding their ignorance, so I prefer communicating with engineers over management types.
