Write a short executive summary

A reader may use an executive summary to decide whether to approve a proposal, ask a question or read the full report. Write for that decision. If the summary follows the document's chronology too closely, it may spend its limited space explaining how the work was done before reaching the point.

Lead with the answer the reader needs

State the central finding or recommendation early, with enough context to make it intelligible. Avoid a dramatic conclusion that outruns the evidence. If the work supports only a provisional recommendation, keep that qualification visible rather than hiding it in the full report.

For a hypothetical content review, a useful opening might say: ‘Update the existing service pages before commissioning new articles. The review found repeated customer questions that those pages do not currently answer.’ This gives the reader a direction and the reason for it. It does not need to begin with the date the review was commissioned.

Select the evidence that explains the recommendation. Two or three relevant findings may be more useful than a long list of observations. Preserve important limits: a review of ten pages should not be described as proof about the entire website, and feedback from a few customers should not be presented as a universal preference.

Make the requested action unmistakable

If a decision is needed, state it. Include the resources, timing or approval involved at the level necessary for that decision. A summary that ends with ‘further work is required’ leaves the reader to invent the next step. Explain what work, why it matters and who would carry it forward.

Include the main trade-off or risk. Removing every difficulty to keep the summary positive can make the recommendation look easier than it is. The reader should know if the preferred route postpones another project or depends on information that has not yet been confirmed.

Write the summary after the underlying document is stable. Then check that every material claim is supported there and that the two versions do not contradict each other. Do not introduce new evidence only in the summary, where a careful reader cannot find its basis.

Finally, ask someone unfamiliar with the work to explain the recommendation after reading only the summary. If they can identify the issue but not the proposed action, the piece is still an introduction. If they can repeat the action but cannot explain why it is justified, add the missing reasoning. Brevity is useful only when the decision remains understandable.
