DEFINITION OF INNOVATION
• Innovation - the use of new technological or market knowledge to offer a new product or service that customers want
• Innovation = invention + commercialization
• Innovation - the adoption of ideas that are new to the adopting organization

New Market Knowledge
• New Product• -Low Cost• -Improved Attributes• -New Attributes
THEORIES OF INNOVATION
• Three general categories
• 1) theories that predict who might innovate
• 2) static theories
• 3) dynamic theories
INNOVATION• Afuah
Innovation is the use of new technological and market knowledge to offer a new product or service to customers.
• A product/service can be considered ‘new’ if: its costs are lowered it has new attributes it is, indeed, a new product or service
Profits
• Profits = Revenues – Costs• = P( z , q ) x q( z ) – C( q ,
z )• where• P = price• C = cost• q = quantity• z = attributes
Value Creation, Costs and Competition
3-10
Overview• Several dimensions are used to categorize
innovations. These dimensions help clarify how different
innovations offer different opportunities (and pose different demands) on producers, users, and regulators.
• The path a technology follows through time is termed its technology trajectory. Many consistent patterns have been observed in
technology trajectories, helping us understand how technologies improve and are diffused.
3-11
Types of Innovation• Product versus Process Innovation
Product innovations are embodied in the outputs of an organization – its goods or services.
Process innovations are innovations in the way an organization conducts its business, such as in techniques of producing or marketing goods or services.
Product innovations can enable process innovations and vice versa.
What is a product innovation for one organization might be a process innovation for another• E.g., UPS creates a new distribution service (product innovation)
that enables its customers to distribute their goods more widely or more easily (process innovation)
3-12
Types of Innovation• Radical versus Incremental Innovation
The radicalness of an innovation is the degree to which it is new and different from previously existing products and processes.
Incremental innovations may involve only a minor change from (or adjustment to) existing practices.
The radicalness of an innovation is relative; it may change over time or with respect to different observers.• E.g., digital photography a more radical innovation for
Kodak than for Sony.
3-13
Types of Innovation
• Competence-Enhancing versus Competence-Destroying Innovation Competence-enhancing innovations build on the firm’s
existing knowledge base• E.g., Intel’s Pentium 4 built on the technology for Pentium III.
Competence-destroying innovations renders a firm’s existing competencies obsolete.• E.g., electronic calculators rendered Keuffel & Esser’s slide rule
expertise obsolete.
Whether an innovation is competence enhancing or competence destroying depends on the perspective of a particular firm.
3-14
Types of Innovation
• Architectural versus Component Innovation A component innovation (or modular innovation)
entails changes to one or more components of a product system without significantly affecting the overall design.• E.g., adding gel-filled material to a bicycle seat
An architectural innovation entails changing the overall design of the system or the way components interact.• E.g., transition from high-wheel bicycle to safety bicycle.
Most architectural innovations require changes in the underlying components also.
3-15
Technology S-Curves
• Both the rate of a technology’s improvement, and its rate of diffusion to the market typically follow an s-shaped curve.
• S-curves in Technological ImprovementTechnology improves slowly at first because it is poorly understood.
Then accelerates as understanding increases.
Then tapers off as approaches limits.
3-16
Technology S-Curves• Technologies do not always get to reach their limits
May be displaced by new, discontinuous technology.• A discontinuous technology fulfills a similar market need by means
of an entirely new knowledge base.– E.g., switch from carbon copying to photocopying, or vinyl records to
compact discs
• Technological discontinuity may initially have lower performance than incumbent technology.– E.g., first automobiles were much slower than horse-drawn carriages.
Firms may be reluctant to adopt new technology because performance improvement is initially slow and costly, and they may have significant investment in incumbent technology
3-17
Technology S-Curves• S-Curves in Technology Diffusion
Adoption is initially slow because the technology is unfamiliar.
It accelerates as technology becomes better understood.
Eventually market is saturated and rate of new adoptions declines.
Technology diffusion tends to take far longer than information diffusion.• Technology may require acquiring complex knowledge or
experience.• Technology may require complementary resources to make it
valuable (e.g., cameras not valuable without film).
3-18
Technology S-Curves• S-Curves as a Prescriptive Tool
Managers can use data on investment and performance of their own technologies or data on overall industry investment and technology performance to map s-curve.
While mapping the technology’s s-curve is useful for gaining a deeper understanding of its rate of improvement or limits, its use as a prescriptive tool is limited.• True limits of technology may be unknown• Shape of s-curve can be influenced by changes in the market,
component technologies, or complementary technologies.• Firms that follow s-curve model too closely could end up switching
technologies too soon or too late.
3-19
Technology S-Curves
• S-curves of diffusion are in part a function of s-curves in technology improvement Learning curve leads to price drops, which accelerate
diffusion
3-20
Diffusion of Innovation and Adopter Categories Everett M. Rogers created a typology of adopters:
Innovators are the first 2.5% of individuals to adopt an innovation. They are adventurous, comfortable with a high degree of complexity and uncertainty, and typically have access to substantial financial resources. Early Adopters are the next 13.5% to adopt the innovation. They are well integrated into their social system, and have great potential for opinion leadership. Other potential adopters look to early adopters for information and advice, thus early adopters make excellent "missionaries" for new products or processes. Early Majority are the next 34%. They adopt innovations slightly before the average member of a social system. They are typically not opinion leaders, but they interact frequently with their peers. Late Majority are the next 34%. They approach innovation with a skeptical air, and may not adopt the innovation until they feel pressure from their peers. They may have scarce resources.Laggards are the last 16%. They base their decisions primarily on past experience and possess almost no opinion leadership. They are highly skeptical of innovations and innovators, and must feel certain that a new innovation will not fail prior to adopting it.

Theory In Action
Technology Trajectories and “Segment Zero” Technologies often improve faster than customer requirements
demand This enables low-end technologies to eventually meet the
needs of the mass market. Thus, if the low-end market is neglected, it can become a
breeding ground for powerful competitors.

Technology Cycles
• Technological change tends to be cyclical: Each new s-curve ushers in an initial period of
turbulence, followed by rapid improvement, then diminishing returns, and ultimately is displaced by a new technological discontinuity.
Utterback and Abernathy characterized the technology cycle into two phases:• The fluid phase (when there is considerable uncertainty about the
technology and its market; firms experiment with different product designs in this phase)
• After a dominant design emerges, the specific phase begins (when firms focus on incremental improvements to the design and manufacturing efficiency).
3-27
Technology Cycles Anderson and Tushman also found that technological
change proceeded cyclically.• Each discontinuity inaugurates a period of turbulence and uncertainty
(era of ferment) until a dominant design is selected, ushering in an era of incremental change.
3-28
Technology Cycles
Anderson and Tushman found that:• A dominant design always rose to command the majority of
market share unless the next discontinuity arrived too early.• The dominant design was never in the same form as the original
discontinuity, but was also not on the leading edge of technology. It bundled the features that would meet the needs of the majority of the market.
During the era of incremental change, firms often cease to invest in learning about alternative designs and instead focus on developing competencies related to the dominant design.
This explains in part why incumbent firms may have difficulty recognizing and reacting to a discontinuous technology.

Drivers of technological evolution
• Paradigms where researchers seek answers based on prior knowledge
• Social, economic, and political forces
• Technology trajectories - paths of improvement of a technology on some performance dimension
• Paradigm shifts necessary to create new opportunities
©2009 Prentice Hall2-32
Radical and Incremental Technological Change
• Most technological innovation is incremental, and involves small improvements to existing technologies
• Some technological innovation is radical, and involves fundamentally new ways of solving a problem
©2009 Prentice Hall2-33
Technology S-Curves
• Graphical representations of the development of a new technology
• Compare some measure of performance with some measure of effort
• The relationship between effort and performance is typically S-shaped: Initially performance improvements per unit of effort
are small Once key drivers of performance are identified rapid
improvement follows Diminishing returns as physical limits reached
©2009 Prentice Hall2-34
The technology S-curve for Intel’s semiconductors
©2009 Prentice Hall2-35
Technological improvements along an S-curve
• Tend to be incremental, building on prior developments, and taking place within an existing paradigm
• Usually done by established firms: they have existing technical, market, and
organizational capabilities they have an existing customer base they have access to internal cash flow to
invest
©2009 Prentice Hall2-36
Shifting S-Curves
• Happens when an existing technology reaches the point of diminishing returns
• A new technology is often developed to challenge the existing technology
• Initially, the new technology is usually inferior to existing technology on key dimensions
• But the new technology has greater potential for performance improvement
©2009 Prentice Hall2-37
Shifting S-curve example
©2009 Prentice Hall2-38
Who Shifts the S-Curve?
• Usually new entrants because: Incumbents have no incentive to introduce the new
technology Incumbents have investments in existing technology Products based on the new technology cannibalize
incumbents’ sales Managers at incumbent firms do not see the new
technology as a threat Incumbent firms can improve the performance of their
old technologies Incumbent firms face organizational obstacles to
changing their core technologies
©2009 Prentice Hall2-39
Using Technology S-Curves as a Management Tool
• Incumbents can predict when to invest in a radical new technology
• Limitations: the inability to identify when to switch technologies the failure to incorporate all of the factors that matter
to the decision to switch the need for adopters of the new technology to focus
on niche markets before tackling the mainstream of the market
the existence of alternative ways respond to the introduction of new technology
©2009 Prentice Hall2-40
The Abernathy-Utterback Model
• Technology evolves through periods of incremental innovation, interrupted by periods of radical innovation
• The development of a radical innovation leads to a fluid phase, during which time many firms enter and compete on the basis of different product designs
• Eventually, the firms in the industry converge on a dominant design, which results in the specific phase, during which time only incremental innovation occurs
• After a while, the cycle repeats itself
©2009 Prentice Hall2-41
The Nature of Innovation and Competition
• Product innovation: when technological innovation involves the creation of new goods and services sold to customers
• Process innovation: when technological innovation involves problem solving that improves the method of creating or delivering a product or service
• Fluid phase dominated by product innovation• Specific phase dominated by process innovation
©2009 Prentice Hall2-42
The Timing of Product and Process Innovation
©2009 Prentice Hall2-43
Firms in an industry
• New firms perform best in the fluid phase: They are better than established firms at
product innovation Less important that they are worse at efficient
production based on scale economies
• During the specific phase, a shakeout typically occurs, with approximately half of the firms exiting the industry; those firms least able to fit their operations to the dominant design tend to exit
©2009 Prentice Hall2-44
Limitations to the Model
• Holds best in assembled manufacturing in which consumers have homogenous consumer tastes
• Holds less well in non-assembled manufacturing, and manufactured products based on non-assembled components
• Does not hold in services
©2009 Prentice Hall2-45
Modifications to the Abernathy and Utterback Model
• Barras’ reverse product cycle theory
• Tushman’s model of competence destroying and competence enhancing innovation
• Christensen’s model of value networks and disruptive innovation
• Henderson and Clark’s model of architectural innovation

Reverse Product Cycle Theory
• Model for service industries
• Stage 1: Adopt a technology from a goods industry to make services more efficient
• Stage 2: Use the technology to make the service more effective
• Stage 3: Use the technology to create new services (radical change)
©2009 Prentice Hall2-49
Competence-Enhancing and Competence-Destroying Innovation
• Radical new technology does not always undermine the capabilities of incumbent firms
• It is competence-enhancing if it makes use of existing knowledge, skills, abilities structure, design, production processes and plant and equipment
• It is competence-destroying if it undermines existing skills, structures, etc.
• Established firms are able to transition to a radical technology when that technology is competence-enhancing but fail to do so when it is competence-destroying
©2009 Prentice Hall2-50
Architectural Innovation
• A modular innovation is one that changes the components from which the innovation is created, but not the linkages between those components
• An architectural innovation is one that changes the linkages between the components, but leaves the components themselves intact
©2009 Prentice Hall2-51
Henderson and Clark’s Taxonomy of Innovations
©2009 Prentice Hall2-52
Why incumbent firms fail in the face of Architectural Innovation
1. Often lack the right external linkages to gather information about a new technology architecture emerging in an industry
2. Often lack the capacity to recognize the value of information about architectural innovation that is presented to them
3. Often have difficulty making use of information because adopting an architectural innovation typically requires a company to restructure
©2009 Prentice Hall2-53
Disruptive Technology and Value Networks
• For new firms: target a new or underserved segment of the market with a disruptive innovation
• For incumbent firms: make sure core technology conforms to the features of the dominant design because deviation from the dominant design will make it harder for you to satisfy customers once that design has emerged
• As an incumbent firm, develop a new company to exploit the disruptive technology, rather than ignoring it, or trying to develop the technology within the confines of your existing organization

Focus on technological component of innovation; bundles technological and market knowledge; bundles component and architectural knowledge.
Strategic Incentive to Invest View
• In this view the type of innovation (radical vs. incremental) determines what type of firm is likely to invest to be first to exploit the innovation.
• A short coming is that this model assumes that firms have recognized the potential of the innovation and, in terms of radical innovation, only the fear of cannibalization prevents them from exploiting it.
Organizational Capabilities
• Incumbents have two problems with radical innovations: since change is competence destroying they may not
have the capabilities to exploit it existing capabilities may not only be useless, they
may actually be a handicap, if culture and processes of the old technology are firmly entrenched
