Giving Presentations & Public Speaking

Why This Matters for Engineering Leaders

You present constantly: sprint reviews, architecture proposals, steering committee updates, all-hands talks, conference talks, hiring pitches. The difference between “that was informative” and “that changed my mind” is almost entirely in structure and delivery. Most engineers over-index on content and under-index on everything else.

The Three Dimensions of Impact

Dimension	Weight	What It Covers
Content	~20%	Facts, data, analysis, depth of knowledge
Structure	~40%	Logical flow, narrative arc, what you include and exclude
Delivery	~40%	Voice, pace, pauses, eye contact, confidence, energy

This ratio is counterintuitive for engineers. You can have the best content in the room and still lose the audience if the structure is unclear or the delivery is flat. Conversely, a well-structured talk delivered with confidence will land even if the content is only 80% there.

Structuring Your Presentation

The Minto Pyramid Principle

Barbara Minto’s framework from McKinsey. The core rule: start with the answer, then support it.

           [Main Point / Recommendation]
          /            |               \
    [Supporting    [Supporting      [Supporting
     Argument 1]   Argument 2]      Argument 3]
    /    \          /    \           /    \
 [Data] [Data]  [Data] [Data]   [Data] [Data]

How to apply it:

1. Lead with the “so what” – state your conclusion or recommendation first
2. Group supporting arguments into 2-4 mutually exclusive, collectively exhaustive (MECE) buckets
3. Support each argument with data, examples, or evidence
4. Never make your audience wait for the punchline

Anti-pattern: The “mystery novel” presentation where you walk through all your analysis chronologically and reveal the conclusion on slide 47. Executives will interrupt you on slide 3.

Situation-Complication-Resolution (SCR)

A narrative structure that creates tension and then resolves it:

Element	Purpose	Example
Situation	Establish shared context – what everyone agrees on	“We currently handle 50K customer service requests per month through our existing system”
Complication	Introduce the problem or change – create tension	“Volume is growing 30% QoQ and our current system can’t scale. We’re already seeing 4-hour response times”
Resolution	Present your solution or recommendation	“We propose building an AI-powered triage system that routes and auto-resolves 60% of requests”

When to use SCR vs. Minto:

• SCR when you need to build a case and the audience doesn’t yet see the problem (persuasion)
• Minto when the audience already knows there’s a problem and wants your recommendation (efficiency)

The Rule of Three

Human working memory holds 3-5 items. Structure every presentation around three key points maximum. If you have more, group them.

Bad: “Here are the seven things we need to do…” Good: “There are three areas we need to address: people, process, and technology.”

Opening Hooks

The first 30 seconds determine whether people listen or check their phones.

Hook Type	Example	Best For
Startling statistic	“We lost 2.3 million euros in the last quarter due to incidents that were preventable”	Steering committees, exec reviews
Question	“What would you do if our main database went down right now and we had no runbook?”	Team meetings, all-hands
Story	“Last Tuesday at 2 AM, our on-call engineer got paged for the third time that week…”	Conference talks, org-wide presentations
Bold statement	“Our current architecture will not survive the next 12 months”	Architecture reviews, strategy presentations

Closing with Impact

End with one of these, not “any questions?”:

• Call to action: “Here’s what I need from each of you by Friday…”
• Callback: Reference your opening hook with the resolution
• Vision: “If we do this right, in 12 months we’ll be…”
• Summary of the one thing: “If you remember nothing else, remember this…”

Delivery Skills

Voice and Pacing

Technique	What It Does	How to Practice
Strategic pauses	Gives weight to key points; lets the audience absorb	Pause for 2-3 seconds after every major point. It feels eternal to you; it feels confident to them
Pace variation	Prevents monotony; signals transitions	Slow down for important conclusions. Speed up slightly for supporting details
Volume variation	Draws attention; emphasizes key phrases	Drop your voice for the most important sentence – people lean in
Eliminating filler	“Um”, “uh”, “like”, “so” erode authority	Record yourself. Replace fillers with pauses. A pause sounds confident; a filler sounds uncertain

Eye Contact

• 50/70 rule: Maintain eye contact 50% of the time when speaking, 70% when listening
• 4-5 second holds: Look at one person for a full thought, then shift to another
• Triangle technique: Rotate between eyes and mouth if direct eye contact feels too intense
• Group presentations: Pick one person per thought. Finish the thought while looking at them, then move to someone else. Cover the whole room over time
• Virtual presentations: Look at the camera, not the screen. This is the hardest habit to build but the most impactful for remote presence

Body Language

• Stance: Feet shoulder-width apart, weight evenly distributed. Don’t sway, pace, or lock your knees
• Hands: Use purposeful gestures. Rest position is hands at sides or loosely clasped. Never in pockets, never crossed
• Movement: Move to signal transitions. Walk to one side for “the problem,” walk to the other for “the solution”
• Energy: Match your energy to the room. Steering committee wants calm authority. All-hands wants enthusiasm. Read the room

Managing Nervousness

Nervousness is physiological arousal. You can’t eliminate it, but you can channel it.

1. Reframe: “I’m not nervous, I’m excited” (research shows this works better than trying to calm down)
2. Breathe: Box breathing (4 in, 4 hold, 4 out, 4 hold) for 2 minutes before you start
3. Power pose: 2 minutes of expansive posture before presenting reduces cortisol (the science is debated, but the psychological effect is real for many people)
4. Know your first 30 seconds cold: Memorize your opening. Once you start smoothly, momentum carries you
5. Arrive early: Own the room before the audience does. Stand where you’ll present. Get comfortable in the space

Slide Design Principles

Less Is More

Principle	Rule	Why
One idea per slide	If you need a second bullet point, make a second slide	Forces clarity and prevents “wall of text” slides
6-word headline	Replace “Quarterly Performance Review Showing Improvements in Several Key Areas” with “Performance up 23% this quarter”	The headline IS the takeaway – if they read nothing else, they get the point
Data visualization	One chart per slide, with the key insight called out	Don’t make the audience interpret the data – tell them what to see
Kill bullet points	Replace bullets with visual layouts, images, or single statements	Bullet points are a document format, not a presentation format
Dark backgrounds	Dark slides with light text are easier to read in most rooms	And they look more polished

The Three Slide Types

1. Assertion slide: A bold statement headline with supporting visual. “Customer churn doubled in Q3” + a single line chart
2. Evidence slide: Data that supports your assertion. One chart, clearly labeled, with the insight called out
3. Transition slide: A single question or statement that bridges sections. “So what do we do about it?”

Handling Q&A

The PREP Framework for Answering Questions

Step	Action	Example
P – Point	State your answer directly	“Yes, we’ve considered that risk”
R – Reason	Explain why	“The main reason is that the alternative introduces more complexity than it removes”
E – Example	Give a concrete illustration	“For instance, when Team X tried that approach last quarter, they spent 3 sprints unwinding it”
P – Point	Restate your answer	“So while it’s a valid concern, we believe the current approach is the better tradeoff”

Handling Difficult Questions

Situation	Response
You don’t know the answer	“I don’t have that data right now. I’ll get back to you by [specific time].” Never bluff.
The question is hostile	Acknowledge the concern without being defensive: “That’s a fair challenge. Here’s how I think about it…”
The question is off-topic	“Good question – let me take that offline with you so we stay on track for the rest of the group”
The question is actually a speech	Wait for them to finish, acknowledge their point, bridge back: “I appreciate that perspective. Let me address the core question I heard…”
You’re being tested	Stay calm, acknowledge complexity, share your reasoning: “There’s a tension there. Here’s how I’m thinking about the tradeoff…”

Anti-Patterns

1. The Data Dump

Showing every analysis you did instead of the 3 things that matter. Your preparation is for you; your presentation is for them.

2. Reading from Slides

If you’re reading your slides, you’re a narrator, not a presenter. Slides are visual anchors, not scripts.

3. Apologizing at the Start

“Sorry, I’m not great at presenting” or “I know this is a lot of slides.” Never undermine yourself before you begin.

4. No Clear Ask

Every presentation to leadership should end with what you need from them: a decision, resources, alignment, or approval. If you leave without an ask, you wasted their time and yours.

5. Going Over Time

Finishing early is professional. Going over time is disrespectful. Plan for 80% of your slot. The remaining 20% is buffer for questions and discussion.

6. Ignoring the Audience

Presenting the same content the same way to engineers, PMs, and executives. Each audience needs different framing, different depth, and different emphasis.

Presentation Preparation Checklist

1. Know your audience: Who are they? What do they care about? What will they resist?
2. Define the one thing: If they remember one sentence, what is it?
3. Structure first, slides second: Outline on paper before opening PowerPoint
4. Rehearse out loud: Not in your head – out loud, standing up, at full volume. At least twice
5. Time yourself: Cut ruthlessly until you’re under time
6. Prepare for the three hardest questions: Write them down and rehearse your PREP answers
7. Check the room: Projector, screen, microphone, internet connection. Arrive early
