Why the best CEOs obsess over their mental model of the market
A great strategy isn’t about having the boldest vision or the slickest PowerPoint; it’s about having the most accurate map of reality and the interrelations.
That may seem obvious, but you’d be surprised how many leaders depend on outdated assumptions or flawed mental models of the world around them. And when your mental model is wrong, your strategy will be too.
Let’s break this down.
Whether you’re running a startup or a multinational, strategy is essentially your best effort to succeed, based on how well you understand your environment. That includes your capabilities, competitors, customers, constraints, and the pace of change in your industry.
If your understanding of any of those factors is incorrect, you’ll make poor decisions—sometimes with deadly consequences.
Systems Thinking Beats Guesswork
Strategic thinkers are also systems thinkers. They don’t just focus on their own company; they aim to understand the entire system: market dynamics, customer motivations, competitors’ actions, and their reasons.
And that second part is crucial. Too often, leaders respond to competitors without understanding their reasoning. We assume our own thoughts onto their actions. That’s how strategic errors occur.
Here’s a real example.
I once ran a capital equipment business. We manufactured in the U.S.—metal bending, steel work, everything. We had a solid team and a great operation, but one of our main competitors moved production to Malaysia. Their prices dropped, and we thought they were cutting corners or sacrificing quality. We convinced ourselves their advantage wouldn’t last.
But it did.
Their quality remained consistent. Their costs were significantly lower. They captured a large part of the market from us. We clung to a flawed idea that “Made in America” and “quality” alone could win the market. But for most of our customers, price was the most important factor. We didn’t see this coming until it was too late.
Lesson learned: never assume your assumptions are right.
Assumptions Kill Good Strategy
Every strategy relies on assumptions. The smartest leaders challenge those assumptions early and frequently.
- Do you believe your customer will pay $1.99/month for your new app? Test it.
- You think competitors can’t match your feature set? Prove it.
- Think your brand loyalty will protect your margins? Find out.
Before investing millions—or months—into a new initiative, take a moment to ask: What assumptions are we making? Which of these haven’t we validated yet?
Validation doesn’t have to be complex. Startups can quickly do customer interviews or landing page tests. Larger companies might run pilot markets or A/B pricing tests. The main point is speed—gather real-world feedback before your assumptions become strategies. The longer you wait without verification, the greater the blind spot.
And don’t forget the emotional trap: we often fall in love with our own ideas. Once we’ve invested time, money, or ego into a strategy, it becomes harder to see flaws objectively. That’s why testing assumptions early—before they become sacred cows—can save you from much bigger, more costly pivots down the line.
Your role as a CEO isn’t about always being right. It’s about being diligent. Foster a culture where people feel comfortable questioning their beliefs and gathering evidence before making big decisions.
Sharpen Your Mental Model
Strategy isn’t developed in isolation. It exists in your mind—and within the collective thoughts of your leadership team. Start there.
Clarify your shared vision of the environment. Describe what you believe to be true about your market, customers, and competitors. Then, test it thoroughly. The more accurate and realistic your mental model is, the more effective your strategy will be.
In business, winners aren’t the ones with the flashiest ideas. They’re the ones who understand the game they’re playing—and play it better than anyone else.
