Pyramid Principle
Lead with the answer; support with grouped logic.
Explanation
Developed by Barbara Minto at McKinsey consulting firm, this method puts your main point first, then explains why. Unlike school essays that build to a conclusion, business communication starts with the answer. Most people decide whether to keep reading within 30 seconds, so lead with what matters most. Group your supporting points into logical clusters of 3.
Real-World Example
Bad: Long background, methodology, data, finally conclusion on page 10. Good: 'We should enter the German market. Three reasons: 1) Market size ($5B) 2) Competitor weakness (no local leader) 3) Our unique advantage (existing partnerships).' Details follow for those who need them.
How to Apply
Start with answer. Group supporting points (usually 3). Make groups MECE. Order by importance. Each group supports conclusion directly. Each point in group relates to group header. Use horizontal logic (across groups) and vertical logic (within groups). Executive summary is just the top level.
