The Pyramid Principle: how to give a clear recommendation
Updated 4 min readBy the MECE Editorial Team
Short answer
The Pyramid Principle structures communication with the answer at the top, a few grouped reasons beneath it, and data beneath each reason. Barbara Minto developed it at McKinsey. In a case interview it shapes your final recommendation: say what the client should do first, then why, then the risks and next steps.
Key takeaways
- Answer first. Your first sentence is the recommendation.
- Two to four reasons, grouped MECE, each backed by a number from the case.
- SCQA sets up the answer: situation, complication, question, answer.
- End with risks and next steps, not a recap.
What is the Pyramid Principle?
The Pyramid Principle says that ideas should be presented as a pyramid: one governing thought at the top, supported by a small set of arguments, each supported by facts. Readers and listeners understand faster when they know the conclusion first, because every detail that follows has a place to go. Barbara Minto set it out in The Pyramid Principle, and it remains a standard in consulting writing.
Recommendation: a Minneapolis bike-share operator should raise its annual pass from $99 to $120
Riders will mostly stay
- Annual members ride far more often than casual riders, so the pass is still cheap per ride
The math works
- The increase pays off unless more than about 1 in 6 members leave
Competitors are not cheaper
- Comparable city passes cost the same or more
- Revenue per 100 members today: 100 × $99 = $9,900
- Members needed at $120 to match it: $9,900 ÷ $120 = 82.5
- So up to 17.5 of every 100 members can leave, about 1 in 6, before pass revenue falls
What is SCQA?
SCQA extends Minto's structure for introductions: Situation (what the audience already knows), Complication (what changed) and Question (what it raises), followed by your Answer. It gets the audience to the answer in a few sentences.
| Part | Example |
|---|---|
| Situation | Our grocery chain has been profitable in the Midwest for 20 years. |
| Complication | Two discount chains opened near a fifth of our stores, and margins there fell by half. |
| Question | How should we respond? |
| Answer | Differentiate on fresh food and service in those stores rather than match prices, because matching costs more than the sales it saves. |
How do you use the Pyramid Principle to close a case interview?
Answer
One sentence with the decision. "The client should enter the Texas market through an acquisition."
Reasons
Two or three, each with a number from the case. Group them MECE: market, economics, feasibility.
Risks
The one or two things that could make you wrong, and how to reduce them.
Next steps
What you would do in the next two to four weeks to confirm the decision.
Interviewer:The CEO just walked in. What should she do?
Candidate:She should close the 12 lowest-performing stores and move that capital into delivery. Three reasons. Those stores lose about $4 million a year between them. Delivery orders in our remaining markets are growing fast and already profitable per order. And the leases on 9 of the 12 expire within 18 months, so exit costs are low. The main risk is losing loyal customers near the closed stores, so I would offer them free delivery for six months. Next, I would confirm the lease terms and test delivery pricing in two markets.
Notice what is missing: no recap of every analysis, no "it depends", and no new analysis at the end. (The chain and its numbers are fictional.)
How do you group the reasons under your answer?
Reasons at the same level should be the same kind of idea and MECE, so they add up to the answer without overlapping. Minto describes two ways to link them. Inductive grouping lists parallel reasons ("the market is growing, we can win share, the economics work"). Deductive reasoning chains them ("costs rose; prices cannot rise; therefore we must cut costs"). In interviews, inductive groups of three are easier to follow.
How do you use the Pyramid Principle at work?
- Email: put the ask or conclusion in the subject line and first sentence. Detail goes below.
- Status updates: lead with whether you are on track, then the one or two things that need a decision.
- Slides: make each slide title a full-sentence conclusion, with the chart below as evidence.
- Meetings: open with the decision you need, not the background.

Frequently asked questions
Who created the Pyramid Principle?
Barbara Minto, who developed it while working at McKinsey and published it in her book The Pyramid Principle. She also named the MECE principle.
Is answer-first always right?
For busy decision-makers, almost always. With a skeptical audience or bad news, you may add one line of context first, but the answer should still come within the first few sentences.
How long should a case recommendation be?
About 60 to 90 seconds: the answer, two or three supported reasons, the main risk and the next steps.
