3. The Idea (it is a process)
“Disruption” describes a process whereby a smaller company with fewer resources is
able to successfully challenge established incumbent businesses.
Specifically, as incumbents focus on improving their products and services for their most
demanding (and usually most profitable) customers, they exceed the needs of some
segments and ignore the needs of others.
Entrants that prove disruptive begin by successfully targeting those overlooked segments,
gaining a foothold by delivering more-suitable functionality—frequently at a lower price.
Incumbents, chasing higher profitability in more-demanding segments, tend not to respond vigorously.
Entrants then move upmarket, delivering the performance that incumbents’ mainstream
customers require, while preserving the advantages that drove their early success.
When mainstream customers start adopting the entrants’ offerings in volume, disruption has occurred.

4. The Disruptive Innovation Model
Product (or service) Performance trajectories x Customer Demand trajectories
As incumbent companies introduce higher-quality products or services to satisfy the high end of the market, they
overshoot the needs of low-end customers and many mainstream customers.
This leaves an opening for entrants to find footholds in the less-profitable segments that incumbents are neglecting.
Entrants on a disruptive trajectory improve the performance of their offerings and move upmarket.

5. Is Uber a Disruptive Innovation?
The theory’s core concepts have been widely misunderstood and its basic
tenets frequently misapplied.
Is a disruption any situation in which an industry is shaken up and
previously successful incumbents stumble?
Is Uber disrupting the taxi business?
According to the theory, the answer is NO.
 Uber was launched in a well-served taxi market.
 Their customers already have the habit of hiring rides.
Disruptive innovations originate in low-end or new-market footholds.
[ two types of markets that incumbents overlook ] Disruptive innovations are
initially considered inferior by most of an incumbent’s customers.
Sustaining innovation, make good products better (incremental advances or
major breakthroughs) in the eyes of an incumbent’s existing customer.
Uber is an outlier. It started on a mainstream market with a competitive
“better” service (in a regulated taxi business).

6. Important points
1. Disruption is a process - it refers to a product or service evolution
over time. Ex: PC x Minicomputers. Netflix x Blockbuster.
“Because disruption can take time, incumbents frequently
overlook disrupters”
2. Disrupters often build business models that are very different
from those of incumbents - it is not just technology.
3. Some disruptive innovations succeed; some don’t - a common
mistake is to focus on the results achieved—to claim that a
company is disruptive by virtue of its success.
4. The mantra “Disrupt or be disrupted” can misguide us -
Incumbent companies do need to respond to disruption if it’s
occurring, but they should not overreact by dismantling a still-
profitable business. Instead, they should continue to strengthen
relationships with core customers by investing in sustaining
innovations. In addition, they can create a new division focused
solely on the growth opportunities that arise from the disruption.

7. New Technology and Strategy Choices
When New Technology arises, disruption theory can guide Strategic Choices.
[ taking a sustaining path x taking a disruptive one (with a new business unit) ]
The theory of disruptive innovation was simply a statement about correlation:
“Empirical findings showed that incumbents outperformed entrants in a sustaining
innovation context but underperformed in a disruptive innovation context”.
Two reasons why:
1 - strategic change is profoundly affected by the interests of customers who provide the resources
the firm needs to survive.
2 - Incumbents’ focus on their existing customers becomes institutionalized in internal processes that
make it difficult for even senior managers to shift investment to disruptive innovations.
[ high margins and targeted large markets with well-known customers ] x
[ smaller markets with poorly defined customers ].
Disrupters work starting with simple products, more convenient, or less costly. And along the time
they improve their products and drive upmarket.
