The Pyramid Principle
by Barbara Minto
Key Ideas
- Bad business writing isn't a style problem — it's a badly packed move that bills the disorder to whoever unpacks.
- The cost of understanding never disappears; it only changes owner — you pay it sorting, or your reader pays it decoding.
- A heading that only names a topic is a box labeled 'misc': it forces you to open it to learn anything.
- An empty label is rarely laziness — it's the tell that you don't yet know what your own points add up to.
- Putting the conclusion on top isn't politeness; it's refusing to bet that your reader reaches the end.
The promise
You spent three days on a document. On the other end, someone opens it, thumbs down the scroll bar, and replies with a single line: "So what do you need from me?" Or the live version, which costs more: you're on slide four when the VP cuts in — "Sorry, where is this going?" It stings because the work was good. What failed wasn't the analysis. It was the handoff.
The instinct in that moment is to fix the prose — shorter sentences, plainer words, a cleaner deck template. It almost never works, because the problem isn't the sentences. It's the order they arrive in. Barbara Minto's ideas go straight at that blind spot. McKinsey hired her in 1963, the first woman it took on as a consultant, and her wager is that clarity isn't a virtue of writing at all: it's an architectural decision made before the first word exists. In this analysis we take the four ideas from that body of work we find most useful, test them against outside evidence, and hand you a way to try them this week on the next email you send.
The idea in one image
Picture a move: forty boxes, one weekend. Two ways to pack it. In the first, you put things in as you grab them — blender with the socks, cables with the mugs, bathroom stuff spread across six different boxes. You finish two hours early and feel wildly efficient. In the second, you group by room and by when things are needed, you write on each box what's inside and when it matters, and you leave one box on top marked OPEN ME FIRST with everything required for night one.
