In more situations than I care to admit, I have sometimes been told during discussions, "Get to the point!", "Great, but my question was...," or even the rare, "I think you have a run-on sentence or two in your essay." I suffer from what I like to call verbosititis, or, talking too much but saying too little! With that, I would like to discuss briefly* how communication is important.
Of course, many forget the other equally important half of communication, listening. Just as ideas must be expressed in a clear and concise manner, one must also ensure that whoever is listening gets the full picture, with no room for misunderstandings. Going back to the example of the SNAFU Principle, by not listening or verifying the validity of what was being said, each "leader" passed on an increasing opposite view of reality to their superiors, resulting in failure.
So in conclusion, remember, if you need to ask a person "What was your question again?," or you hear "Go for it," instead place of "Don't do it," you should probably work on those communication skills.
*Or at least briefer than if I were given the opportunity to speak in person ... and maybe given enough time too.
