Writing at work: the one-page memo that gets a decision

Most workplace writing asks the reader to do the thinking. A memo that leads with the answer, states what it needs, and fits on one page is the single most transferable skill we see.

Writing at work: the one-page memo that gets a decision

What is happening

A good memo is not a shorter report. It is a different object: a decision document. It opens with the recommendation, gives the three reasons that carry it, names the main risk, and says exactly what it needs from the reader (a yes, a budget, a date). Everything else is support, placed after the answer so the reader can stop early without missing the point.

This structure has a name and a long history in consulting: the pyramid principle, in which the conclusion sits at the top and the arguments beneath it are grouped and ordered. You do not need the whole method. You need the habit of asking, before you type, "what do I want the reader to decide, and what is the one sentence that says it?"

Why it matters

Managers read upward in a hurry. A page that makes the decision easy is remembered as competence; a page that makes the reader reconstruct your reasoning is remembered as effort, at best. Writing is the one skill that is visible in every function at every level.

What this means for you

Fresh graduateYour first memos will be short status notes; write them with the answer first anyway. The habit is noticed long before the big documents arrive.
Early professionalThis is the year you start proposing, not reporting. The one-page format is how a proposal survives a busy inbox.
Experienced professionalSenior readers will judge the memo on whether the risk and the ask are honest. Lead with those two when the recommendation is contested.

What to do

  1. Write the last line first. One sentence: "I recommend X because Y; I need Z by date." If you cannot write it, you are not ready to write the memo.
  2. Give three reasons, each a sentence with a fact in it. Reasons without facts are opinions wearing a suit.
  3. Name the strongest objection and answer it in two lines. A memo that hides the risk teaches the reader not to trust the next one.
  4. Cut until it fits one page, then cut the adjectives. Put tables, data and method in an appendix the reader can open or ignore.
  5. Read it aloud once before sending. Any sentence you stumble on, the reader will stumble on twice.

Do it with the pillars

The Route
The Route’s visibility lessons are where the memo becomes a career instrument, not just a document.

Sources & provenance

The structure follows Barbara Minto’s pyramid principle as practised in consulting firms; the one-page discipline is Metanoia’s editorial reading of how Indonesian corporate and state-enterprise managers actually read.
