It's Mostly Review

In business writing--as I'm currently learning in my MCom 320 class--there are different types of messages and for those different types, various ways to present information to an audience, depending upon who that audience happens to be. A company picnic email vastly differs from a business proposal. A no-brainer.
For those messages that are informative, there is a certain way to write; for those which are persuasive in nature, there is a preferable approach. For persuasive messages, ensure that your argument or reasoning is sound; any fallacy will weaken your stance with the intended audience.
This is not anything new to me but perhaps awakening my faculties to actually considering all this at the very forefront of my brain, is something I hadn't previously done.
And there are other lessons to be learned about basic inter-office communication as far as emailing and document scanning etc. goes.
It's a practical class I suppose, although some of it feels more redundant and obvious.
Of course, I've been around a while longer than the average student in there. Most certainly my field of reference is more expansive.
