Disruptive innovation

Joseph L. Bower and Clayton M. Christensen introduced the theory behind disruptive innovation in their 1995 article “Disruptive Technologies: Catching the Wave.” A disruption begins with a business model that serves overlooked low-end customers or enables new customers to participate, then improves until it can challenge established providers in the mainstream market.

When to use it

Use the theory to examine how a well-managed incumbent can still be displaced. Established firms often see the emerging technology, but their customers, margins, processes and resource-allocation rules make the early opportunity unattractive. A start-up with a different cost structure and value network can pursue it.

Two principal patterns are:

• Low-end disruption. The entrant serves overserved, price-sensitive customers with a simpler, more affordable offer. Incumbents may willingly retreat because the segment is less profitable. The entrant then improves and moves upmarket while preserving a cost or business-model advantage.
• New-market disruption. The entrant makes consumption possible for people who previously lacked the money, skill, access or convenience required by existing solutions. Growth comes from non-consumption before the offer competes directly with incumbents.

A radical or successful innovation is not automatically disruptive. The path through an overlooked foothold and subsequent movement toward the mainstream is essential to the theory.

Origins

Bower and Christensen published the core argument in 1995. Christensen developed it further in The Innovator’s Dilemma, explaining why rational investment in the needs of an incumbent’s best customers can cause the organisation to miss a smaller, initially inferior-looking market. Later work refined the distinction between low-end and new-market footholds and emphasised the enabling business model rather than technology alone.

What it is

The diagram contrasts the performance customers can use with the trajectories of sustaining improvement and an entrant that begins below mainstream requirements. As the entrant improves, it becomes “good enough” for progressively more demanding customers.
