McKinsey Presentation Principles
1. The Pyramid Principle (Barbara Minto)
- Start with the answer: Every slide headline is the conclusion
- Top-down structure: Executive summary → Supporting arguments → Detailed evidence
- MECE organization: Mutually Exclusive, Collectively Exhaustive groupings
- Storyline first: Narrative flow before slide creation
2. One Message Per Slide Rule
- Each slide has ONE key message in the headline
- Headline is a complete sentence stating the insight (not a topic)
- Body supports the headline with evidence
- Bad: "Market Analysis"
- Good: "The premium segment is growing 3x faster than mass market, representing our best opportunity"
3. Slide Structure Standards
Mandatory Elements:
- Headline: Action-oriented, insight-driven (not descriptive)
- Body: Clean visual or data supporting the headline
- Source: Always cite data sources (bottom left)
- Page number: Bottom right
- Optional: Interpretation box for complex data
Slide Design Guidelines

Visual Hierarchy
HEADLINE: The main insight (18-20pt, bold)
─────────────────────────────────────────
[Visual/Chart/Framework]
Supporting text (10-12pt)
• Bullet points are concise
• Maximum 3-5 bullets
• Each bullet is one line ideally

Chart Excellence
- Always label directly - no legends if possible
- Highlight the insight - use color to draw attention to key data
- Simplify - remove gridlines, unnecessary labels, chart junk
- Round numbers - $4.7M not $4,678,432
- Show the "so what" - annotate charts with implications
