You don't write the same way to top management, your peers or the public. Tailor your approach to each. Omit unnecessary words. Start with a simple topic sentence containing that idea. Follow with details, examples and definitions.
Good writing means rewriting.
That's not always possible, especially when you're talking about ideas. Or you might take a lesson from the safety announcements given by airline flight crews prior to takeoff. They don't mention just why you might need to be floating or the frightening necessity of determining how long you can tread water. For the airlines, obscurity here is the best policy. But for most of us, clear writing provides more brownie points.
