How Great Companies Are Built: Strategy vs Execution
Why the Brilliant Plan Is Usually the Easy Part
Almost every company that failed had a strategy worth admiring — what killed them was the thousand unglamorous decisions that came after.
The Idea
There is a seductive idea in business culture that strategy is the hard part — that if you can just figure out the right move, the right market, the right positioning, execution will follow naturally. It won't. And the gap between these two things explains more corporate obituaries than almost anything else. Strategy is, at its core, a theory about how the world works and where you fit in it. It lives in decks, memos, and offsite conversations. It is intellectually satisfying to construct and easy to believe in. Execution is something else entirely: it is the daily, grinding, often boring work of making the theory real — aligning incentives, communicating across departments, hiring people who can actually do the thing, and adjusting when reality turns out to be different from the model. What makes this genuinely surprising is that research consistently shows the bottleneck is almost never the quality of the strategy. A McKinsey study tracking hundreds of companies found that execution accounted for the majority of performance variance between firms in the same industry with similar strategies. The companies weren't choosing differently — they were doing differently. This matters because it reframes where great companies actually earn their advantage. It is rarely in a secret insight nobody else has. It is in the institutional capacity to follow through — consistently, at scale, over time — when doing so is inconvenient, expensive, or politically uncomfortable inside the organisation.
In the World
In the early 2000s, Blockbuster's leadership was not blind to what Netflix represented. By 2004, the company had commissioned internal strategy documents that correctly identified streaming and mail-order rental as existential threats. Senior executives understood the model. They even launched a competitive DVD-by-mail service, Blockbuster Total Access, that by some metrics outperformed Netflix on value. And then execution killed them — not from the outside, but from within. Blockbuster's largest franchisees, who operated stores independently, lobbied against the mail service because it cannibalised their in-store revenue. Activist investors pushed back against the cost of the transition. A new CEO was brought in partly to cut spending, and one of the first things cut was the very programme that was working. Total Access was quietly wound down. Netflix, meanwhile, was executing relentlessly and unglamorously: optimising its recommendation algorithm, managing its DVD logistics with unusual precision, and building a subscriber base that would eventually make streaming viable. Reed Hastings wasn't working from a strategy Blockbuster didn't have. He was building an organisation that could actually do the thing the strategy required. Blockbuster's failure is often told as a story of strategic blindness. It wasn't. It was a story of an organisation that couldn't align itself to act on what it already knew — which is a much harder and more human problem.
Why It Matters
This distinction changes how you read any ambitious plan — whether it's a business you're evaluating, a company you work for, or a goal you've set yourself. When someone presents a strategy, the interesting question isn't 'Is this a good idea?' It's 'Does this organisation have the capacity, culture, and incentives to actually do it?' A brilliant strategy in the hands of a misaligned team, or a leadership structure that will buckle under internal pressure, is worth very little. For your own working life, it suggests that the skill most worth developing isn't strategic thinking — though that matters — it's what you might call execution intelligence: the ability to anticipate where follow-through breaks down, to spot the internal friction points before they kill the plan, and to build habits and systems that survive the moments when motivation runs cold. The best operators tend to be quieter than the best strategists. They don't get the speaking slots at conferences. But over ten or twenty years, they are the ones who actually built something.
A Question to Ponder
Think of something you genuinely believe would improve your work, your finances, or your life — where exactly does your execution break down, and what would have to change for it not to?
