From Ghost Deck to Final Report: Solving the Consultant’s "Too Many Slides" Problem

Consultants are facing problems. Although data availability has increased a lot, the “thoroughness” of a consulting report has become its greatest trouble.

TL;DR (Boardroom Ready)

  • The Problem: Decks are growing (35% longer) while executive attention shrinks (30% less time).
  • The Solution: Build a “Ghost Deck” (narrative skeleton) before designing a single slide.
  • The Framework: Use Insight First Design™ to ensure the key takeaway is the hero.
  • The Tactic: Move 80% of your data to the appendix. Visualize only the insights that drive the recommendation.

As per latest report published by A1 Slides, the proprietary research across 60+ enterprise projects, the average Fortune 500 presentation now contains 35-40% more slides than it did five years ago. Yet, during that same period, available executive review time has reduced by approximately 25-30%.

The result is an increasing  “Insight-to-Action Gap.” When consultants confuse evidence with insight, they produce decks that are analytically sound but strategically ineffective. The solution isn’t just better design—it’s better architecture of the deck and that  starts with the Ghost Deck.

The "Kitchen Sink" Syndrome: Why More is Less

In most consultancies, they  build presentations bottom-up. So you gather data, run analyses, and then paste every chart into PowerPoint to “show your work.” This usually stems from a defensibility mindset but this approach ignores the reality of executive time usability. 

The sole purpose of going through your slides is to make decisions based on your slides. 

When insights are buried under visual clutter or convoluted narratives, they introduce decision risk. Just imagine the dependencies, 74% of leaders cite the boardroom slide deck as their primary decision-enabling tool,  If that tool is not sharp, the decision is delayed.

We call this the Kitchen Sink Syndrome: the inclusion of every supporting data point in the main narrative. The fix requires a shift to a methodology where the key takeaway is the hero. 

This is the core principle of Insight First Design™ —ensuring that design serves the logic, not the other way around.

The Ghost Deck Strategy: Narrative Before Design

A Ghost Deck is a slide-by-slide outline without a single chart or graphic. It a deck without design and shows  logical skeleton of your content

Before opening PowerPoint, you must map the Horizontal Logic. This is important,if you read only the headlines (action titles) of your 20-slide deck, they should form a story and sense what you presenting 

Our belief is that if the logic breaks in the Ghost Deck phase, no amount of design will save the final report.

The Anatomy of a Ghost Deck Structure

A1 Slides uses a narrative structuring process that forces clarity before design begins. This mirrors the “Pyramid Principle” used by top-tier strategy firms:

  1. The Situation (Slide 1-2): What is the undisputed current reality?
  2. The Complication (Slide 3): Why is the current status quo unsustainable? (The “Burning Platform”).
  3. The Resolution (Slide 4-Main): What is the core recommendation? (Answer-First).
  4. The Proof (Slides 5-15): Only the specific evidence required to prove the resolution.

By validating this structure first, you avoid the “Rework & Clarifications” cycle that accounts for 15% of wasted effort in unclear projects.

The Rule of Precision: 1 Slide = 1 Idea

Fortune 500 leaders look for precision. Our client feedback consistently emphasizes the need for presentations where coordination is “immaculate” and messages are immediately clear.

To achieve this, apply the “One Slide = One Decision-Driving Idea” rule.

If a slide contains three distinct charts making three different points, it is not a slide—it is a document. Split it. If a slide contains raw data without a clear takeaway, it is not an insight—it is noise.

Case Study: The Power of Strategic Compression

We recently worked with a senior manager at a €150B+ automotive manufacturer. She had a career-defining opportunity to present to the board but was struggling with an 11-slide deck that senior leadership refused to review due to length constraints.

We restructured the narrative using three principles:

  1. Storyline Architecture: Sequencing the data to reduce cognitive load.
  2. Visual Translation: Replacing text-heavy explanations with intuitive infographics.
  3. White Space Discipline: Giving the eyes a place to rest.

The result was a 6-slide presentation that was measurably more impactful than the original 11 slides. This proves that strategic compression doesn’t lose detail; it heightens focus.

Checklist: From Ghost Deck to Final Report

Use this checklist to ensure your consulting deck is ready for the C-Suite.

PhaseAction ItemSuccess Metric
1. Ghost DeckWrite all headlines (Action Titles) on a blank page.Can you read the headlines as a single coherent paragraph?
2. AuditCount the total slides. Move 30% to the Appendix.Does the core deck fit within the executive’s time window (e.g., 20 mins)?
3. Logic CheckApply the “So What?” test to every chart.Does every chart have a clear takeaway that supports the narrative?

Conclusion: Value Your Client's Attention

In 2025, the ability to rapidly transform complex data into decision-ready presentations is a competitive advantage. Companies that master this skill don’t just have better meetings—they move faster than the market.

If your team is struggling with 14-day review cycles or repeated requests for “more clarity,” the issue likely isn’t the data. It’s the design.
