A Critique of Grammatical Coverage in Business-Communication Textbooks 
Business English (BE) and business communication (BC) overlap. English handles linguistic mechanics and style, whereas communication holistically discusses the movement of a message from one person to another. The BC discipline, unfortunately, allows language basics into its pedagogy like a statistics course teaching fundamental mathematics. From the other side, some English courses teach BC before their students are able to handle that material. A subject teaches prepared students. If they are deficient, they are either kept out or the subject matter suffers.

When you set yourself up as a grammar expert it's better than being an expert on plastics. To be an expert on plastics you actually have to know something about plastics. With grammar the analogous thing doesn't hold. Nobody asks, nobody checks, nobody knows enough to get suspicious. You are free as a bird to publish any garbage you might want to type out.
