Clear business writing isn't about fancy words — it's about structure. Two simple structures, BLUF and the Pyramid Principle, make almost any document instantly clearer. Here's how to use both.
BLUF: Bottom Line Up Front
Put your conclusion or ask in the first line. 'Bottom line: we should sign by Friday. Here's why.' Busy readers get the point immediately and decide how deeply to engage. Never bury the lede.
The Pyramid: answer, then support
Lead with your main point, then group your supporting reasons beneath it — ideally three. It reads top-down, so the reader always knows where you're going and why.
