Distance From Core Should Be Measured in Capability, Not Category
The most influential growth-strategy research of the last two decades says the safest path to growth is expansion close to the core. The framework built based on that principle is measuring the wrong type of distance — and that one error explains a surprising share of adjacency growth's failures.
The Research Behind the Thinking
Chris Zook and James Allen's research at Bain — built on studying thousands of companies and interviewing the CEOs of top performers — established the core discipline behind adjacency growth: expand into territory close to the core, master one adjacency before moving to the next, and avoid dramatic leaps into unrelated industries. From this research, practitioners built the Adjacency Expansion Matrix, a tool that scores every growth option on two axes: distance from the core, and the value that can realistically be captured.
It's a genuinely useful discipline, widely taught and widely applied. The related-diversification literature backs the same principle from a different angle: diversifying into territory that applies a company's known strengths carries meaningfully lower risk than diversifying into domains with limited connection to current operations.
Even applied faithfully, adjacency growth still fails often — over a ten-year period, fewer than three in ten businesses succeed at it, even across multiple attempts. That failure rate is too high to explain with bad execution alone.
The standard tools measure distance in category terms: same industry, adjacent product line, same broad sector. A move that stays inside a familiar category label scores as close to the core. A move into a different-sounding category scores as farther away and riskier. That's intuitive, easy to apply — and wrong often enough to matter, because category label and underlying capability are not the same thing, and they frequently point in opposite directions.
A move can look like a small, safe step and still fail, because the label matches but the underlying skill doesn't. A move can look like a large leap and still succeed, because the underlying skill transfers even though the category doesn't.
Four Real Moves, Scored Two Ways
The clearest way to see the gap is to score the same real moves on both axes — category distance, the way the standard framework does it, and capability distance, measuring the actual underlying skill being carried forward.
In every case, the category-distance score and the outcome point in opposite directions. The capability-distance score doesn't. A framework applied exactly as intended would have called Microsoft's move the safer bet and Disney's the bigger risk. The real result was the reverse — because the framework was scoring the wrong axis.
The Call
The standard adjacency frameworks are right about the underlying principle and incomplete about the measurement. Distance from the core should be scored against a company's real, demonstrated capability — not against how similar two industry categories sound on paper. When the two measurements agree, the standard tools work fine.
When they disagree, capability distance is the one worth trusting, because it's the one that actually predicts whether the underlying skill transfers.
Four Questions, In This Order
For any proposed growth step, a testable sequence — something you can actually run against a real decision, not just a mental checklist:
01
Microsoft → Consumer Hardware (Zune, Windows Phone)
Category distance: near — “still technology.”
Capability distance: far — enterprise software and platforms share almost nothing with consumer device design, hardware supply chains, or retail channel management. Outcome: failed, repeatedly.
02
Disney → Television
Category distance: far — different medium, different operating model from theme parks.
Capability distance: near — franchise-building, character IP, and audience loyalty transferred directly. Outcome: succeeded.
03
Amazon → Consumer Hardware (Fire Phone)
Category distance: near — “still e-commerce-adjacent, still tech.”
Capability distance: far — retail operations and platform economics have little to do with consumer hardware design or an entrenched mobile ecosystem. Outcome: failed.
04
Amazon → Cloud Infrastructure (AWS)
Category distance: far — retail company into enterprise infrastructure.
Capability distance: near — directly leveraged Amazon's proven capability for building and operating massive, reliable computing infrastructure. Outcome: succeeded.
Why the Category Label Still Wins
This isn't an argument against adjacency growth, or against the discipline Zook and Bain's research established. Staying close to a company's real strengths is still the soundest general principle in growth strategy, and the underlying research holds up.
The correction is narrower: "distance" has to be measured against demonstrated capability, not industry category — and the two are close enough, often enough, that the difference goes unnoticed until a move that looked safe on paper fails for reasons the standard framework was never built to catch.
Growth frameworks built around staying close to the core are not wrong to prize proximity — proximity is genuinely protective, and the research behind that conclusion is sound.
What determines whether a specific move actually benefits from that proximity is whether the company is carrying forward a proven capability or simply a familiar label.
Distance from core should be measured in capability, not category. Still tech isn't still your strength.
What the Scoring Doesn't Tell You
The four-question sequence and the category/capability scoring split are Zook and Bain's research, applied directly — any team can run both scores on their own next growth decision.
The harder call sits one step past that: when the two scores genuinely disagree, how much weight the disagreement deserves varies by industry and by how far apart the two scores actually land, and neither Zook's original research nor the sequence above settles that on its own.
That calibration is what Strategic Innovation — Vaxa's proprietary methodology, referenced across engagements including Nokia, Intel, DuPont, and P&G — and is built to povide.
The Actual Question
When your last adjacency decision named its capability, was it tested against where that capability had actually been proven — or did the category label do the reassuring instead?
This relates to Vaxa's Growth Strategy.
