Overview
In consulting, slides aren’t decoration, they are the final deliverable. All the research, analysis, and insights eventually take shape as a deck that communicates your recommendations clearly to clients. Your thinking is only as strong as your ability to present it.
Case competitions follow the same principle. You may do brilliant analysis, but if your slides aren’t structured and clean, judges will never see the full strength of your solution. That’s why slide-making becomes such an important skill for aspiring consultants.
This guide covers how consultants design slides that are sharp, logical, and insight-driven, the kind of decks that create impact.
Why Slide Decks Matter in Consulting
Consultants use slides to:
- synthesize insights
- highlight key findings
- frame recommendations
- align stakeholders
- drive decision-making
Every project ends with a deck.
Partners present it, clients rely on it, and teams refine it repeatedly.
Even though interviews don’t test slide-making, the moment you join a consulting team, it becomes a daily responsibility.
Why Slide Decks Matter in Case Competitions
Case competitions mimic real consulting work.
You:
- Solve the business problem
- Build insights
- Form recommendations
- Present them through a slide deck
Judges evaluate:
- clarity of storyline
- crispness of slides
- insight hierarchy
- structure
- communication flow
Winning teams stand out not because they found the most data, but because they presented the right insights in the right way.
Storytelling + slides = competitive advantage.
The Consulting Slide Formula
Consulting decks follow a predictable, simple structure:
1. Title Slide
Concise and clean, only what’s necessary.
2. Executive Summary (Answer First)
Consultants start with the recommendation.
Then list 2–3 reasons why it’s right.
3. Situation & Problem Statement
Define the problem clearly.
Set the context in 3–4 bullets.
4. Key Insights / Drivers
Use charts and visuals to highlight:
- what’s happening
- why it’s happening
- what matters most
Each slide should communicate one key message.

5. Recommendations
Clear, actionable, logically grouped.
Usually presented in 2–4 buckets.
6. Impact & Feasibility
Quantify whenever possible.
Show expected business outcomes.
7. Implementation Roadmap
Timeline, phases, priorities.
Helps the audience see the next steps clearly.
8. Risks & Mitigations
Shows practical thinking and awareness of real-world challenges.
9. Appendix
Extra charts, assumptions, data tables.
5 Rules for Consultant-Grade Slide Design
Rule 1: One Message Per Slide
Your title = your key insight.
No vague headings.
Rule 2: Keep It Minimal
More whitespace → clearer thinking.
Avoid decorative elements.
Rule 3: Be MECE Everywhere
Your bullets, charts, and logic should be structured and non-overlapping.

Rule 4: Let Charts Tell the Story
Highlight the takeaway, not the graphic.
Rule 5: Make Slides Scannable
Partners should understand a slide in 5 seconds.
Mini Example (Insight Slide)
Title (key message):
Customer churn increased due to long wait times during peak hours.
Body:
- chart with peak-hour spikes highlighted
- 2–3 bullets explaining the insight
- simple visual (clock or queue icon)
This is consultant-grade clarity.
