How to Write an Executive Summary: A Step-by-Step Guide

Learn how to write a concise, persuasive executive summary in minutes! Follow this simple, step-by-step guide—plus see how Merlin AI can brainstorm points, sharpen wording, and polish your summary for a confident pitch.

When my manager first asked me to “attach a quick executive summary” to a 30-page proposal, I typed three pages of copy-and-paste extracts—then wondered why leadership barely skimmed it.

The feedback was blunt: “Great details, but we just needed the gist in one page.”

Since then, I’ve drafted (and salvaged) dozens of executive summaries for product pitches, grant proposals, and annual reports. I eventually discovered a simple formula that works almost every time.

Below are seven practical steps to craft a focused, compelling executive summary that decision-makers can absorb in under five minutes. I’ll also point out where Merlin AI can jump in to shave half an hour off the process.

Why Executive Summaries Matter

  • First impression: Busy executives often read only the summary before deciding whether to dive deeper.
  • Clarity filter: It forces you to crystallize the big picture—problem, solution, value—in plain language.
  • Decision trigger: A concise summary speeds approvals, funding, and next steps.

Spending 45 focused minutes on a tight executive summary can make or break a multimillion-dollar green-light.

Step 1 Clarify Purpose, Audience, and Length

  • Purpose: Is this summary attached to a proposal, business plan, grant application, or research paper?
  • Audience: C-suite, investors, funding board, or internal department heads?
  • Length: Many orgs expect 5–10% of the parent doc, capped at 1–2 pages (≈ 300–500 words). Always ask or check the template.

Quick Merlin Move Paste the project brief into Merlin and prompt: “Identify the primary decision-maker, key metrics they care about, and target length for the executive summary.” Voilà—your north-star parameters.

Step 2 : Gather Key Points with the 4-Q Checklist

Answer four questions in bullet form:

QuestionBullet Example
What’s the problem/opportunity?“Onboarding takes 20 days—double the industry average.”
What’s your solution?“A self-serve training portal + role-based paths.”
What’s the impact/ROI?“Cuts onboarding to 8 days, saves $25k/quarter.”
What do you need?“$19k budget + 10-week timeline.”

Spend 10 minutes filling this table; it becomes your summary skeleton.

Step 3 Craft a Sharp Opening Hook (1–2 Sentences)

Executives decide in seconds whether to keep reading. Lead with a data-driven statement:

“Acme Corp loses $42k each quarter due to a 20-day onboarding process—twice the industry norm. Our proposed, self-serve portal will cut that time to 8 days, saving $25k within three months.”

✅ Problem + Impact + Solution in ≤ 50 words ✅ Use numbers and plain English; skip jargon

Merlin Assist Prompt: “Write three 40-word opening hooks using these bullet points; professional tone, data-driven.” Choose the strongest and polish.

Step 4 – Summarize the Solution and Benefits (1–2 Short Paragraphs)

Describe how you’ll solve the problem—at a high level—then show the payoff.

Structure:

  • Solution snapshot:

    “The portal delivers 15 video modules and real-time analytics.”

  • Key benefits:

    “Reduces manager training hours 40%, boosts new-hire satisfaction 30%.”

  • Strategic alignment:

    “Supports Q3 productivity OKR.”

⏱ Keep it 120–150 words—concise yet specific.

Step 5 – Outline High-Level Timeline and Costs (Bullet Format)

Decision-makers crave clarity.

Timeline:

  • Week 1: Kickoff & discovery
  • Weeks 2–4: Content creation
  • Weeks 5–7: Portal build & test
  • Week 10: Full rollout

Budget Summary:

  • Discovery workshops – $3,000
  • Development – $12,000
  • Training materials – $4,000
  • Total – $19,000

Bullets beat paragraphs here; readers can scan and move on.

Step 6 – Add Proof of Capability (One Crisp Paragraph)

“Our team built a similar portal for Beta Co., trimming onboarding time 55% and earning a 4.8/5 user rating. The same UX lead and engineer will drive this project.”

✅ Include metrics, prior wins, or brief testimonials ⏱ No more than 80 words

Quick Merlin Move Feed Merlin past-project bullets and prompt: “Condense into a 70-word capability paragraph.” Instant credibility paragraph.

Step 7 : Close with a Clear Call to Action

End by telling leadership exactly what you need:

“We seek budget approval by 30 June to begin on 8 July and complete rollout by 13 September. Please reply ‘Approve’ or contact me by Friday for questions.”

✅ Bold the date or action verb if your style guide allows; you want the next step unmistakable.

FAQ

Is an executive summary the same as an abstract? No. Abstracts summarize research for academic audiences. Executive summaries target decision-makers and include recommendations or asks.

Can it exceed one page? Only if guidelines allow. If you’re over 500 words, trim or move details to appendices.

Should I include charts? If space permits, a single chart can clarify ROI or timeline—just ensure it’s legible in print or PDF.
