What is the pyramid principle and how does it change the way you communicate findings?

The pyramid principle, developed by Barbara Minto, structures communication so the answer comes first and everything below it supports that answer.

The structure:

• The governing thought at the top — the recommendation or key finding, stated in one sentence.
• Supporting arguments beneath it, ideally three, which are MECE and each independently support the conclusion.
• Evidence beneath each argument — the data, analysis and examples.

Why it matters: executives read the top and stop unless they need to challenge something. A detective-story structure that builds to a conclusion frustrates senior audiences and buries the point.

How it changes practice:

• Slide titles state the insight, not the contents. "Two products drive 70% of the margin decline" rather than "Margin by Product". Reading only the titles should convey the whole argument.
• The executive summary is written last but read first, and should stand alone.
• Supporting detail goes to the appendix, available but not obstructing the narrative.

Note: The discipline this imposes is knowing what to leave out. Including everything you analysed dilutes the recommendation and signals that you could not distinguish what mattered.
