Kodak invented the digital camera in 1975. Blockbuster had the chance to buy Netflix for $50 million. Borders could have been Amazon.
What do these companies share? They all fell victim to what Dr. Rita McGrath calls the most dangerous threat in business: the insidious creep of your own outdated assumptions.
In a recent episode of The Insurgent Mindset, we had the privilege of diving deep with Rita—Columbia Business School professor and acclaimed author of The End of Competitive Advantage and Seeing Around Corners—on how leaders can detect the subtle signals of disruption before they become existential threats. Rita’s blog Thought Sparks is a must-read among forward-thinking strategists, and her frameworks have shaped thinking at companies ranging from Microsoft to Mastercard. Her decades of research on strategic inflection points and innovation aren’t just valuable; they’re survival training for the modern executive.
Here’s what every leader needs to know about navigating uncertainty, dismantling dangerous assumptions, and building the dynamic capabilities that separate winners from casualties.
Strategic Inflection Points: When the Ground Shifts Beneath Your Feet
Industries don’t evolve smoothly. They lurch.
Rita’s foundational insight is that business landscapes are punctuated by “strategic inflection points”—critical moments when the bedrock assumptions supporting your business model begin to crack. The cruel irony? Success breeds the very blindness that kills you.
“When you’ve optimized around a stable set of rules, it’s hard to imagine the game changing,” Rita explained. Your best practices become your worst enemies when the rules shift overnight.
But here’s the twist that caught our attention: Being first to market isn’t what matters. “The first mover to reconfigure capabilities usually wins.”
This means Netflix didn’t win simply by inventing streaming—they won because they were first to aggressively reconfigure their capabilities and rebuild their entire organization around a fundamentally different model. While Blockbuster was optimizing late fees, Netflix was optimizing for convenience and then leveraging algorithms. Same market, different game entirely, played with a new playbook.
The lesson for leaders? Your competitive advantage isn’t your products or services. Your competitive advantage is your ability to adapt and rebuild from a position of strength, not desperation.
The Assumption Trap: Why Smart Leaders Make Catastrophic Bets
Rita has spent years dissecting corporate disasters—Disney’s European expansion, FedEx’s ZapMail, Anheuser-Busch’s Drinkworks, Quibi’s streaming ambitions. The pattern is chilling in its consistency.
“I found lots of assumptions taken as facts,” Rita observed, “coupled with very little low-cost testing.”
The culprit? Time pressure and ego. Leaders feel compelled to make “big-bang” decisions with massive upfront investments, operating under the dangerous illusion of certainty. They plan to be right instead of planning to learn.
Rita’s antidote is brutally simple: “We have a piece of paper so that you and your teammates understand what you believe to be true about the state of the world. And then we reduce that uncertainty through a series of checkpoints.”
This is discovery-driven planning in action. Document your assumptions. Test them cheaply. Learn your way forward rather than betting the company on untested beliefs.
Think of it as strategic humility—acknowledging that when you’re doing something genuinely new, uncertainty is your starting point, not your excuse.
But even leaders who master strategic adaptation face another insidious trap: the danger of losing touch with the very customers who define your market.
The Customer Proximity Problem: The Executive Blindspot that Grows with Success
Here’s a story Rita shared that should terrify every executive: An elevator maintenance company operated on the assumption that customers valued speed above everything else. Their entire operation optimized for faster repairs.
One simple question—”Are you sure?”—uncovered a massive customer segment that actually prioritized quality and long-term reliability over quick fixes. They’d been optimizing for the wrong thing entirely.
Rita calls this the proximity problem: “Senior leaders may at one point have had a really good read on the customer, but that read gets old over time.”
The solution isn’t more customer surveys. It’s systematically including voices from the edges of your organization—customer service reps, front-line employees, anyone in direct customer contact. These people see the gaps between your assumptions and customer reality.
The most dangerous sentence in business? “We know our customers.”
The most powerful question? “How do we know what we know?”
Innovation as System, Not Accident
Most companies treat innovation like lightning—hoping it strikes, but unable to predict when or where.
Rita advocates for something radically different: innovation as an orchestrated system. Not random R&D experiments, but deliberate environments where “smart bets can be placed,” rapid learning is embedded, and resources can fluidly shift toward what actually works.
This requires cultural surgery. You need to rewire organizational DNA to value intelligent experimentation over perfect execution. To view learning from uncertainty not as failure, but as essential progress toward a breakthrough.
The companies that master this don’t just survive disruption—they create it.
Your Strategic Imperative: Three Actions for Tomorrow
Rita McGrath sees a generation of leaders emerging who possess something their predecessors often lacked: the courage to challenge not only the status quo, but their own deeply held beliefs.
If you want to join their ranks, here’s your playbook:
- Embrace uncertainty as a competitive advantage. Your competitors are still trying to predict the future. You’re going to learn your way into it.
- Document and test your core assumptions. That “obvious” truth about your market? Put it on paper. Find the cheapest way to test it. Be prepared to be wrong.
- Get dangerously close to your customers. Not their feedback—their actual, evolving jobs to be done. Let front-line insights challenge C-suite assumptions.
The leaders who thrive in the next decade won’t be the ones with the best predictions about the future. They’ll be the ones with the best systems for adapting to whatever future actually emerges.
Ready to challenge your assumptions? Start by identifying one “fact” about your industry that everyone accepts but nobody questions. That’s your first checkpoint.
