What it means
A genuinely disruptive entrant does not beat the incumbent at its own game. It enters at the low end or in a market that did not exist before, offering something that established customers would initially consider inadequate, and it makes money at a price the incumbent cannot match with its existing cost base.
The reason incumbents struggle is structural rather than stupid. Their best customers want more features, their sales teams are paid to chase larger contracts, and their finance function quite reasonably prefers investments with higher margins, so the cheap and unimpressive entrant is never the obvious thing to fund.
What turns a low-end product into a threat is its improvement trajectory. If the entrant's capability improves faster than mainstream customer requirements rise, it eventually becomes good enough for the middle of the market, and at that point the price advantage becomes decisive.
Contrast this with sustaining innovation, which makes existing products better for existing customers. Sustaining innovations are usually won by incumbents, because they have the resources and the customer relationships to execute them, which is exactly why the distinction is worth keeping precise.
For a manager, the practical question is not whether a competitor is exciting but whether it is improving faster than the customer requirement is moving. Tracking that gap year by year is far more useful than debating whether a rival deserves the disruptive label at all.
In practice
Real-world examples.
Example
A regional accountancy firm ignores a $29 a month bookkeeping app because its own clients need consolidated group accounts. Four years later the app handles multi-entity consolidation, and the firm loses a third of its small-company base in eighteen months.
Example
A commercial airline dismisses a low-cost carrier that flies from secondary airports with one aircraft type and no connecting flights. As the low-cost carrier adds routes and business travellers begin choosing it for short trips, the incumbent has to launch a separate low-fare brand to defend the market.
Example
A medical device maker selling $180,000 hospital scanners watches a startup sell $9,000 portable units to rural clinics that were never customers. The startup's image quality is initially poor, but each generation improves, and within several years hospitals begin buying the portable units for bedside use.
Formula
Calculation
Entrant capability after n years = starting capability x (1 + annual improvement rate) to the power of n, expressed as a percentage of what mainstream customers require
Suppose an entrant's product currently delivers 40% of the capability mainstream customers demand, and it improves that capability by 25% a year while customer requirements stay broadly flat. The trajectory runs 50% after one year, 62.5% after two, 78.1% after three, 97.7% after four, and 122.1% after five. The entrant therefore crosses the mainstream requirement during the fifth year, which means an incumbent watching only current capability would see a harmless competitor for four years and a direct rival in the fifth.Case study
Seen in the real world.
Meridian Legal Systems is an illustrative, fictional supplier of contract management software sold to large corporate legal departments at around $240,000 a year. Its board reviewed a startup offering a simplified version at $6,000 a year to small businesses and concluded, correctly at the time, that the product could not handle the complex clause libraries its own clients required.
Over the next four years the startup added features at a rapid pace because its architecture was simpler and its customer base was more tolerant of imperfection. By year five it handled roughly 90% of what mid-sized legal teams needed at a twentieth of the price, and Meridian began losing renewals in the mid-market segment it had always treated as an afterthought.
Meridian's eventual response was to build a stripped-down offering run as a separate unit with its own cost base and sales model, because the existing organisation could not sell a $9,000 product profitably. This illustrative story shows the classic trap: the incumbent's judgement about the product was right, and its judgement about the trajectory was wrong.
Watch out
Common mistakes.
- Calling every new or fashionable product disruptive, which drains the term of meaning and makes it useless for actual strategy discussions.
- Judging an entrant by what it can do today rather than by how quickly it is improving relative to customer requirements.
- Asking an existing business unit to sell the cheap defensive product, when its cost structure and sales incentives make that impossible to do profitably.
Questions
People also ask.
Is disruptive innovation the same as new technology?
No, it is a market and business model pattern; the underlying technology is often ordinary, and the disruption comes from serving overlooked customers at a lower cost.
Can a large company disrupt itself?
Yes, but usually only by setting up a separate unit with its own cost base, targets and freedom to sell at prices the parent would consider unattractive.
How do you spot disruption early?
Look for a competitor with lower margins, simpler products, customers you do not want, and a capability curve rising faster than your customers' expectations.
