Disruptive Innovation: What the Theory Explains and How to Use It

Understanding competitive footholds, incumbent incentives, and the evidence needed to assess an emerging threat.

Disruptive Innovation: What the Theory Explains and How to Use It

An established software company sells a reporting platform to large organisations. Its customers want more integration options, stronger controls, and specialised support. A smaller competitor offers a simpler product to small teams that find the established platform too expensive and difficult to use.

The incumbent knows about the competitor. Its next investment still goes towards the features requested by larger customers, where demand and revenue are easier to justify. The smaller company continues improving its product outside the part of the market the incumbent prioritises.

This is a useful starting point for examining disruptive innovation. It presents conditions that could support a disruptive trajectory without establishing that one will occur. The smaller company still needs to serve customers economically, improve its offering, and become relevant to a broader market.

What Disruptive Innovation Means

The Christensen Institute describes disruptive innovation as a process through which an entrant can challenge an established business by starting with overlooked customers and subsequently moving towards mainstream demand. The concept concerns the relationship between customers, performance, and the business model supporting an offer.

The reporting competitor’s simpler product is initially less suitable for complex enterprise work. Its limited functionality may still suit teams that place greater value on an affordable tool they can use without specialist help. That trade-off creates room to serve a segment the incumbent has less reason to pursue.

A foothold becomes part of a disruptive trajectory when the offer improves enough to attract customers the incumbent values. Remaining a successful small-team tool would be a different outcome. Size, novelty, and rapid growth alone do not establish the process.

The distinction helps keep the framework useful. It directs attention to where competition begins and how it develops, instead of treating every important market change as the same kind of threat.

Distinguishing Low-End and New-Market Footholds

The Institute’s primer identifies two routes. Low-end disruption begins with customers who are overserved by existing offerings. New-market disruption begins by enabling people who previously could not access or use the established alternative.

For the reporting company, a low-end possibility would involve customers already buying complex software but using little of its functionality. A simpler offer might meet their requirements at a lower price, provided the entrant can sustain the service at that price.

A new-market possibility would involve teams that currently manage without a reporting platform because they lack the money, time, or expertise to adopt one. The initial comparison is then with their existing workaround or inability to complete the task.

The same product could attract both groups, but the distinction changes the investigation. The company needs to establish whether customers are switching from an established offer or gaining access to something they previously could not use. Those findings affect the size of the opportunity and the response it may require.

Why Incumbent Investment Can Favour Existing Customers

The reporting incumbent has a reasonable case for serving its larger customers. They provide revenue, have identifiable requirements, and support the company’s operating model. The smaller segment may need lower prices and a different sales or support process to be viable.

The Institute contrasts sustaining and disruptive innovation through these market relationships. Sustaining improvements serve an established performance trajectory, while a disruptive entrant develops from a less attractive foothold and moves towards more demanding customers.

For management, the difficult choice is how much to invest before the emerging opportunity becomes substantial. Assigning engineers to a simpler product may delay work requested by existing clients. The new offer may also draw customers away from a more profitable package before it produces comparable returns.

Digital adaptation therefore involves resources and operating commitments as well as awareness. A leadership team can understand the possible threat while remaining uncertain about what response the available evidence justifies.

Examining Whether the Entrant Can Progress

The reporting company should investigate what limits the competitor today and whether those limits are changing. A product may work well for a small dataset but struggle with more demanding access controls, reliability requirements, or integrations. Reaching a broader market depends on addressing requirements those customers actually value.

Customer movement is important evidence. The incumbent can examine which organisations choose the alternative, what they stop buying, and why they consider the trade-off acceptable. Trials and publicity may indicate interest without demonstrating replacement or sustained use.

Economics matter alongside capability. An attractive price is not enough if each new customer requires more support than the business can afford. Conversely, a different delivery or acquisition model may allow the entrant to serve customers the incumbent cannot profitably reach through its existing organisation.

These questions produce a hypothesis that can strengthen or weaken. If customers return, delivery costs become manageable, and adoption expands into more demanding use cases, the concern becomes more credible. If those changes fail to appear, the initial foothold may remain limited.

Keeping the Competitive Mechanism Specific

A premium competitor can threaten the incumbent directly with a more capable product for its largest customers. That requires attention, but it presents a different problem from an entrant developing in a segment the company finds unattractive. The Institute’s discussion of head-on competition explains why the starting market matters to the theory.

Technology alone does not settle the classification. Imagine two hypothetical uses of AI in reporting. One improves the incumbent’s enterprise product for its existing customers. Another lets teams without analytical expertise produce a basic report for the first time. Their competitive implications depend on the customers, economics, and subsequent development of each offer.

The company should investigate those differences before deciding how to respond. A direct challenge may require improving the established product. An emerging segment may justify a separate offer or a limited experiment. Using the same label for both can obscure the choice.

Designing a Response That Can Learn

The incumbent does not need to choose immediately between ignoring the smaller company and rebuilding its whole business. It can test a simpler reporting offer with a defined group of customers and examine the requirements, demand, and cost of serving them.

That experiment needs enough independence to test different assumptions, together with access to capabilities it might need later. A team without customer access or a route into production can demonstrate an idea while leaving the company unable to act on the result.

Measures should follow the uncertainty being investigated. Early work might examine whether customers can complete the task and return without assistance. Later decisions need stronger evidence about reliability, retention, acquisition costs, and the resources required to expand.

The decision owner should establish what would justify further funding, revision, or closure. If the evidence supports expansion, leadership also needs to identify which existing commitments will change. A pilot becomes a strategic response when the organisation can move the staff, budget, and authority needed to support it.

Using the Theory Within Its Limits

Disruptive innovation offers a way to examine a particular competitive process. It helps the reporting company ask whether a neglected segment gives an entrant room to develop and whether that development is beginning to affect customers the incumbent values.

Those questions can inform a forward-looking assessment without guaranteeing an outcome. Product development, customer requirements, financing, regulation, and competitor responses can all change the trajectory. The company needs to review the hypothesis as those conditions evolve.

For this incumbent, the useful result is a clearer account of what to watch and what action the evidence would support. It can continue serving established customers while testing whether a different offer deserves investment. The theory contributes when it makes those choices more precise and leaves uncertainty visible enough to revisit them.
