The PremiseThe Premise
“This book is about the failure of companies to stay atop their industries when they confront certain types of market and technological change. It’s not about the failure of simply any company, but of good companies – the kinds that many managers have admired and tried to emulate, the companies known for their abilities to innovate and execute.”

The DilemmaThe Dilemma
“…the logical, competent decisions of management that are critical to the success of their companies are also the reasons why they lose their positions of leadership.”

Relationship to CourseRelationship to CourseThe development, management, and commercialization (DMC) of technologyDilemma is how to handle all of these tasks in the face of disruptive technologiesDisruptive technologies may change industries in the long runConflicts can arise within organizations– Across functional departments– Across technologies in the firm’s portfolio– Across market segments– Across time (short and long run)

The Key ConceptThe Key Concept
“There is a strategically important distinction between what I call sustaining technologies and those that are disruptive.”
“These concepts are very different from the incremental-versus-radical distinction that has characterized many studies…”
![Page 11: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/11.jpg)
Sustaining TechnologiesSustaining Technologies
Sustaining technologies foster improved product performance.– They can be discontinuous or radical, or
they can be incremental– Always improve performance of
established products along dimensions valued by mainstream customers in major markets
![Page 12: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/12.jpg)
Disruptive Technologies (1)Disruptive Technologies (1)
Disruptive technologies result in worse product performance, at least in the near term.– Emerge occasionally– Bring to market a different value
proposition than available previously– Underperform established products in
mainstream markets– Have features that fringe/new customers
value

Disruptive Technologies (2)Disruptive Technologies (2)
“Products based on disruptive technologies are typically cheaper, simpler, smaller, and frequently more convenient to use”– Small off-road motorcycles– Transistors and transistor radios– HMOs (!)

Additional FactorsAdditional Factors
“…technological progress can, and often does, outstrip what markets need.”
…customers and financial structures of successful companies color heavily the sorts of investments that appear to be attractive to them, relative to certain types of firms.”

Principles of Disruptive Principles of Disruptive InnovationInnovation
1. Companies depend on customers and investors for resources
2. Small markets don’t solve the growth needs of large companies
3. Markets that don’t exist can’t be analyzed
4. Technology supply may not equal market demand
![Page 18: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/18.jpg)
Resource Dependence (1)Resource Dependence (1)“…companies find it very difficult to invest
adequate resources in disruptive technologies – lower-margin opportunities that their customers don’t want – until their customers want them. And by then it is too late.”
Solution: “…set up an autonomous organization charged with building a new and independent business around the disruptive technology.”
![Page 19: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/19.jpg)
Resource Dependence (2)Resource Dependence (2)• This is an argument about internal incentives
within an organization• These incentives play an important role in
determining the cost structure, which Christensen argues differs across high and low margin businesses
• Think of the airlines and their unions – it’s not just a question of margins, but of being locked into cost structures that cannot be varied across different lines of business within a company, especially if those lines are close
![Page 20: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/20.jpg)
Market SizeMarket Size
First mover advantages in emerging marketsHarder for big companies to enter small new marketsGrowth targets to satisfy investors bias efforts toward large marketsSo this assumes that firms are not long run profit maximizers – maybe a key requirement for Christensen’s argument to work
![Page 21: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/21.jpg)
Market AnalysisMarket AnalysisIf markets for disruptive technologies cannot be quantified, this biases resource allocation away from themThere is an implicit assumption here about internal incentives and individual risk-taking within an organizationIn large organizations, this may lead to risk aversion in decision-makingThe argument may also be couched in terms of policies and procedures, or organizational inertia, a kind of lock-in, perhaps
![Page 22: Innovators Dilemma-prof. n Singh-ppt](https://reader034.vdocuments.mx/reader034/viewer/2022052401/55cf9921550346d0339bbc93/html5/thumbnails/22.jpg)
Supply and DemandSupply and DemandCompetition leads to oversupplying performance relative to what customers wantLeaves room at the low end of the market for products based on disruptive technologiesThis implicitly assumes that firms cannot simultaneously produce different products (i.e., vertical product differentiation)Goes back to internal organizational constraints, or to reputational spillovers

Sustaining technological changes– Grinding ferrite heads finer (incremental)– Smaller, more finely dispersed oxide
particles (incremental)– Innovation in product architecture (14”
Winchester drives – discontinuous)Disruptive innovations (series)– Further shrinking the drives (8”, 5.25”, 3.5”)

Case Study: Disk Drives (2)Case Study: Disk Drives (2)For minicomputer manufacturers, 8” drive was superior to 5.25” drive – Capacity– Cost per megabyte– Access time
For PC makers, though, 5.25” drive was– Small– Lightweight– Relatively cheap

Case Study: Disk Drives (3)Case Study: Disk Drives (3)Seagate was innovator in 5.25” drivesSeagate personnel showed 3.5” drives to customers for evaluationOpposition came from marketing and executives, who argued that the market wanted higher capacity and lower cost per megabyteExisting customers showed little interestSeagate finally shipped 3.5” drives three years lateCannibalization versus new marketsFear of cannibalization can become a self-fulfilling prophecy

Value NetworksValue Networks• Existing value networks support sustaining
innovations• Disruptive technologies get their start in new
value networks• There is an implicit argument here about lock-
in through irreversible investments upstream• Value networks increase lock-in, but lock-in
can occur even with internal irreversible investments
• Downstream, the value network involves customers with differing wants

Services vs. Products Services vs. Products Disruptive innovations can be in services as well as products – Retailing– Airlines
In either case a want is being satisfied, with the disruptive innovation providing an innovative mix of characteristicsDisruptive innovations in services will involve process innovation, more so than in productsProcess innovation may put more strain on existing organizational structures

Conclusions Conclusions (Christensen’s Dilemma)(Christensen’s Dilemma)
Christensen has a precise notion of disruptive technologies, which is often misrepresented, and confused with discontinuitiesUnderlying his arguments are some economic issues that need to be looked at in more detail– Internal organizational incentives and attitudes,
including risk aversion and fairness– Assumptions about how capital markets work,
possibly promoting short-termism and risk aversion
– Lock-in and irreversibility seem to be key underlying factors in the “innovator’s dilemma”

Conclusions (DMC)Conclusions (DMC)Dilemma is how to handle DMC of technology in the face of disruptive innovationDisruptive technologies may be industry-changingConflicts can arise– Across functional departments– Across technologies in the firm’s portfolio– Across market segments– Across time (short and long run)
Incentive structures (internal) and market structures (external) are key to these conflicts
