Roy Jacobsen at Writing, Clear and Simple has posted an excellent article on business jargon, available as a 14-page PDF download. His thesis statement:
Why is so much business writing--news releases, ad copy, product brochures, white papers, reports, e-mails, presentations, letters, manuals, and, of course, memos--so painfully bad?
He answers the question with a list of reasons--abstraction, obscurity, misdirection, and lack of writing skill--among them. And he gives some practical remedies, including:
Educate colleagues. When you have an opportunity to review anything, whether it's an internal document or something for public consumption, use your feedback as an informal teaching platform. ...
Ridicule blatant b.s. The authors of Why Business People Speak Like Idiots ... started a "Serious Bull" contest at the consulting company where they worked: They asked coworkers to send in prize-winning examples of obfuscation, inflation, and smoke-blowing. ...
Energize colleagues. Seek out and send people copies of research findings that show taking time to craft straightforward language is a good business investment.
