Gary Hamel vs Clayton Christensen: Reinventing Management or Surviving Disruption?
Comparing Gary Hamel's strategic innovation and management innovation with Clayton Christensen's disruptive innovation: how each explains why incumbents fail and what each recommends.
When established companies lose to newcomers, two explanations get repeated. Clayton Christensen says the newcomers disrupt from below while incumbents rationally look elsewhere. Gary Hamel says incumbents fail because their strategies and management systems have not changed. People compare them to decide whether the problem is the market or the organization.
What is the core difference?
Christensen studies a pattern. Small entrants begin by serving customers incumbents neglect, improve over time, and eventually capture the mainstream. Incumbents miss it because their processes and best customers pull them toward higher-end offerings.
Hamel studies the incumbent's inner workings. Strategy goes stale, and management systems built for efficiency block experimentation. His remedy is to reinvent strategies and the way work is managed.
One looks at the market and says the threat is predictable. The other looks inside and says the barrier is self-made.
What does Christensen say?
The Innovator's Dilemma (1997) distinguishes sustaining innovations from disruptive ones. Disruptive innovations start with overlooked customers, either at the low end or in new markets, and improve until they meet mainstream needs. The Innovator's Solution (2003), with Michael Raynor, advises managers, often by setting up a separate unit.
A 2015 Harvard Business Review article by Christensen, Raynor, and Rory McDonald clarified how the term should be used. Critics have questioned the theory's evidence and its predictive power. Christensen died in 2020.
What does Hamel say?
Gary Hamel, a strategy professor and writer, co-authored with C.K. Prahalad the 1990 article on core competence and the book Competing for the Future (1994). Leading the Revolution (2000) argued for strategy innovation by incumbents and entrants alike.
The Future of Management (2007, with Bill Breen) argues that management itself is a technology that needs innovation. Humanocracy (2020, with Michele Zanini) makes the case against bureaucracy. Hamel's work relies on company examples and a manifesto style, and he has advised many corporations.
How do they compare?
| Dimension | Hamel | Christensen |
|---|---|---|
| Main explanation of failure | Stale strategy and bureaucratic management | Rational focus on current customers, ignoring disruptive entrants |
| Where the problem sits | Inside the organization | In a pattern between incumbents and entrants |
| Recommended response | Reinvent strategy and management systems | Create a separate unit or pursue the disruptive market deliberately |
| Key ideas | Core competence, strategic intent, management innovation | Sustaining versus disruptive innovation, jobs to be done |
| Evidence | Company examples and advisory experience | Industry case studies (disk drives, steel) |
| Main criticism | Examples that did not endure; manifesto tone | Predictive power and loose use of the term |
| Best known for | Competing for the Future (1994), The Future of Management (2007) | The Innovator's Dilemma (1997) |
When does each one fit?
Christensen's lens fits when you suspect something small and cheap is gaining ground and you want to understand why your organization is not responding. It also fits when deciding whether to compete in a low-end or new market.
Hamel's lens fits when the symptoms are internal: slow decisions, layers of approval, ideas dying in process, and good people frustrated. It asks what in the management system causes it.
When the market threat is clear but your organization cannot act, both are needed. If the organization is healthy but the market is shifting, Christensen's questions come first.
What does this look like in practice?
A publisher is losing readers to free online content. A Christensen reading asks whether the entrants began with readers the publisher ignored, whether they are improving, and whether the publisher's economics make it irrational to follow. The likely remedy is a separate unit with different economics.
A Hamel reading asks why the publisher takes eighteen months to try a new format. Who approves experiments, how are budgets allocated, and which assumptions about readers have not changed in a decade? The remedy is in the management system. In practice, the unit Christensen proposes would also need the freedom Hamel advocates.
"Our company is [description] and we are losing ground to [competitor or trend]. First, from Christensen's view, assess whether the threat looks disruptive: where it started, who it serves, and how it has improved. Then, from Hamel's view, list three features of our management system that slow our response, such as approval layers, budget cycles, or career incentives, and suggest an experiment to change one."
Why it works: one lens finds the external pattern, and the other finds the internal block.
Can you use both together?
Yes. A reasonable sequence is to diagnose the external threat with Christensen, then ask Hamel's question about why the organization cannot respond. The remedies reinforce each other: a separate unit helps only if it is allowed to work differently.
The shared warning is that success makes organizations conservative. Both texts urge deliberate action before the numbers force it.
"We want to try [new offering] without the core business killing it. Design the experiment: how it should be separated, what freedoms it needs from our usual processes, how we will judge it differently from the core, and who protects it. Point out where Christensen's separation and Hamel's management innovation both apply."
Why it works: a protected experiment needs both an independent structure and permission to work differently.

Frequently asked questions
Do Hamel and Christensen disagree on why incumbents fail?
They emphasize different causes. Christensen argues that well-run firms ignore disruptive entrants because serving current customers is rational. Hamel argues that firms fail to reinvent their strategies and management systems, and that bureaucracy and inertia are the deeper problem. Both can be true at once, and they suggest different remedies. The sensible test is to look at your own company for both signs: a quiet entrant at the edge, and internal habits that slow your response.
What is a core competence?
It comes from C.K. Prahalad and Gary Hamel's 1990 Harvard Business Review article, The Core Competence of the Corporation. They argued that a firm's lasting advantage lies in collective skills that span products and can be extended into new markets. It was later developed in Competing for the Future (1994). The idea shifted attention from products to capabilities. The idea matters because it explains why firms that are strong at some capabilities can still be unable to move into adjacent markets.
What does Hamel mean by management innovation?
In The Future of Management (2007, with Bill Breen), Hamel argues that new ways of organizing and managing, such as decentralized decision making or radically open information, can be a source of advantage as much as new products. Humanocracy (2020, with Michele Zanini) argues against bureaucracy and for organizations that release human capability. Humanocracy is the most explicit statement of his argument that large firms carry too much bureaucracy and that people have more to give.
What does Christensen recommend for incumbents?
In The Innovator's Dilemma (1997) and The Innovator's Solution (2003, with Michael Raynor), Christensen suggests that incumbents facing disruption often need a separate organization with its own processes and economics to pursue the new business. The aim is to avoid forcing a disruptive idea through systems built for the core business. The separate unit works only if it is given real authority, its own metrics, and protection from the core's planning and budget processes.
Is either framework criticized?
Yes. Disruption theory has been challenged on its evidence and predictive power, and often used loosely. Hamel's ideas have been criticized for relying on a series of celebrated company examples that did not always endure. In both cases the frameworks are better treated as lenses that generate questions than as laws of business. Read the original sources for a fuller view, since popular summaries tend to lose the conditions each author attached to the argument.
Can AI help me apply them?
It can help you list entrants that might be disruptive, draft questions about your management practices, and compare your habits to examples in the books. It cannot see inside your organization. Use it to organize hypotheses, then test them with real data and conversations. Treat everything it proposes as a hypothesis, and verify it against data on customers, costs, and your own decision speed.
