When One-Pagers Win

3 min read

A one-pager is not a short presentation. It is a standalone document designed to drive a decision in the absence of its author. It works in three specific contexts — and it fails in every other context where a different format would serve better.

Use case one: the pre-read summary. The one-pager circulates before a meeting to give participants the recommendation and context they need to engage substantively. The meeting is not an orientation. The one-pager is the orientation. When the one-pager works, attendees arrive knowing what is being decided and prepared to decide.

Use case two: the leave-behind. After a meeting where you have presented verbally, you leave a physical or digital document that captures the recommendation and the ask. The executive who was in the room will refer to it when writing the follow-up email or briefing their CFO. The executive who was not in the room will use it to get up to speed.

Use case three: the decision brief. A senior executive missed the meeting, declined the meeting, or needs to make a decision independently. The one-pager is the entire case — recommendation, evidence, ask — in a format they can read in three minutes or less. The decision brief must work without any supplementary materials, without context from a meeting, and without the author to clarify.

Do This

  • Identify which use case applies before writing the first sentence — it determines the opening
  • Pre-read: open with context, then recommendation. Leave-behind: open with recommendation. Decision brief: open with recommendation and compress everything else
  • Match document density to use case — a decision brief is denser than a leave-behind
  • Include the ask in every version — even a pre-read should state what the meeting will decide

Avoid This

  • Write one template and use it for all three contexts — the structure is different enough to require adaptation
  • Open every one-pager with background context — executives who already have context do not need orientation
  • Omit the ask from a pre-read — the reader needs to know what they are being asked to decide before the meeting
  • Write a one-pager for a topic that requires a full presentation — one-pagers are for decisions, not education
