Fear not scared speakers and questionable writers: Garry Kranz has written a book to help you out. And college students will probably find some factual gems in this little guide as well.
This April release is chocked with tips and tricks for the perfect company manager, with nifty "do-and-don't" checklists and "knowledge assessment" quizzes that fele a bit too much like homework. Even still, those aiming towards a Business or Communications major will find this short read helpful in many ways.
Communicating Effectively covers professional writing, including the ideal approach to messages between work colleagues or subordinates (no matter how evil that sounds); the electronically-enhanced route to communication, including email, IM-ing, and videoconferencing; and face-to-face talk, from being the bearer of bad news to being the director pitching a great idea to their company. Its clear, concise wording allows for easy and speedy understanding, and thus comes to your aid in a pinch.
So if you feel a little self-conscious about that speech you're about to make, you might consider hiding this little booklet under your notes.
