Modularity and industry evolution
At the birth of many industries, a few firms develop all
or almost all the components necessary to make the products. As
industries evolve, what generally happens is that specialized firms
emerge to develop certain components of the larger puzzle. An
increasing number of industries today consist of different
firms that each develop one component of a big jigsaw puzzle.
Economists refer to these industries as "de-integrated." This
evolution has happened in the computer industry, where companies
like vertically integrated IBM and Digital Equipment Corporation
(DEC) have left center stage for a specialist, hardware component
maker, Intel, and a specialist, software component maker,
Microsoft—and the plethora of complementary developers around
them.
The reasons industries evolve this way are widely discussed, but
a central tenet of many theories is the concept of modularity. A
module is a unit whose structural elements are powerfully
connected to each other and relatively weakly connected to elements
in other units. Clearly there are degrees of connection, thus there
are gradations of modularity. Many industries of complex products
have evolved toward a more modular architecture, including the
computer, telecom, and automotive industries. Consequences of
modular designs reach far beyond the purely technical
characteristics of the products, for example, the physical shape of
the product or its internal structure. 4
Design decisions affect the organization of production, and modular
designs provide the means for people to divide up the work in tasks
or groups of tasks that are relatively independent of each other.
Modularity in product design has a powerful impact on innovation:
Innovation can happen on modules of the product without having to
impact (and thus threaten the integrity of) the overall system.
In addition to modular designs, the vast improvement in tools of
communication is another factor accelerating the pace of innovation.
The development of the Internet, for example, has reduced
tremendously the difficulties of coordinating work on discrete
modules or components across distant locations and fostered
collaboration on new products.
Another aspect of modern industry is the ubiquity of software.
Organizations and individuals have used software tools in a
pervasive manner to achieve improvements on products and processes.
Software expertise—fueled by developments in computer higher
education and the ubiquity of cheap PCs—has also reached
unprecedented levels and availability. The combination of these
factors leads to the fact that technological innovation—once
restricted to the labs of rich and powerful companies—has never been
so prevalent and widely distributed. Barriers to innovation are at a
historical low.
The ability for an increased number of actors to innovate
separately on different modules of systems is radically altering the
nature and stability of relationships between the firms that make
core products and the developers of complementary products. This
book analyzes the strategies that executives at Intel, Microsoft,
Cisco, Palm, NTT DoCoMo, and supporters of the Linux operating
system, have developed for facing these challenges. Their strategies
differ in many respects, but they also share many similarities. Each
group, in their own way, follows an approach that we have called
platform leadership.
Platform leadership
Platform leadership refers to the common objective sought
by the companies we talked to: to drive innovation in their
industry. The increased breadth of innovation described earlier
creates the necessity for either one firm or a group of firms to
ensure over time the integrity of an evolving platform. It also
creates strategic opportunities to channel the direction of
innovation on complementary modules or products. Ensuring the
integrity of the platform and driving its evolution become strategic
imperatives in industries where distributed innovation constantly
challenges established relationships of power between suppliers of
complementary products.
More and more firms want their products to become the
foundation on which other companies build their products or offer
their services; that is, they want to become platform leaders. A
platform leader can benefit from—but is also highly dependent
on—innovations developed at other firms. Platform leaders might rest
easier if they had the resources to create the core components and
all possible complementary products themselves for every market
around the world. But this is impossible. No single company can
replicate all the innovative capabilities of a market, especially at
a time when tools and knowledge necessary to innovate are more
widespread than ever. As a result, nearly all the platform leaders
we observed have had to work closely with other firms to create
initial applications and then new generations of complementary
products. Platform leaders and complementary innovators have great
incentives to cooperate, however, because their combined efforts can
increase the potential size of the pie for everyone.
From the perspective of the platform leader, complements are both
a curse and a blessing. They can be a curse when a firm that depends
on complements developed externally fails to get them created in a
timely manner or at a high enough level of quality or volume. On the
other hand, complements can draw new customers in, inducing them to
buy the core product. For Microsoft, whose core product is the
Windows operating system, a large number and variety of
complementary Windows-compatible software applications are a
blessing because it encourages potential customers to buy
Windows-based computers. Likewise, having a large number and variety
of movies on VHS-compatible videocassettes available in video stores
pushed the sales of VHS recorders. The availability of a large
number of complementary products adds value to the core
product. Innovation on complementary products, therefore,
constitutes a great opportunity.
In short, in industries that center around platform products, the
value of a platform increases when there are more complements. The
more people who use these complements, the more incentives there are
for complementary producers to introduce more complementary
products, which then stimulate more people to buy or use the core
product, stimulating more innovation, and so on. It is, therefore,
in the interest of a platform leader to stimulate and channel
innovation on complementary products.
The game is risky, though, because platform producers may fail to
get other firms to cooperate and innovate, and this failure can lead
to greatly reduced sales for everyone tied to the same platform.
Since platforms are made of components that interact following
standard interfaces, standard wars are necessarily part of platform
strategies. Examples include Sony and the Betamax standard, which
failed to dominate the VCR market, and the Apple Macintosh line of
PCs, which has found some resurgence in recent years but has not
unseated Windows machines as the mass-market standard. DEC's Alpha
microprocessor failed to garner much of a following, mainly because
of a lack of software applications. Informix has found a niche in
the corporate database software market, but lost out to Oracle and
Microsoft as the industry standard. QUALCOMM is in the midst of a
global struggle with companies such as Nokia, Ericsson, AT&T,
and Motorola to establish its technology as the international
standard for next-generation wireless cell phones.
The Navigator browser, which fit into a platform and once had a
market share of around 90 percent, declined sharply in popularity as
a result of Netscape's inability to keep it as the industry
standard. 5
Microsoft's Pocket PC operating system may suffer a similar fate at
the hands of Palm or other competitors if Microsoft cannot persuade
more companies to adopt their system for their handheld computers
and personal digital assistants (PDAs), cellular telephones, or
cable TV set-top boxes.

In other words, it is quite possible to fail to become a platform
leader and to mismanage the process of stimulating and
channeling complementary innovation. The result is an inability to
exploit the dynamics of markets driven by the economic forces we
have described. Of course, there are no guarantees of success in
high-tech markets, where change can be quick and brutal. The VHS
platform for the VCR and what has been called the "Windows-Intel"
platform for the PC are now standards, but their originators did not
win their markets easily or by accidents. 6
Managers and engineers at Intel, Microsoft, Cisco, Palm, and other
successful platform leaders, as well as platform leader "wannabes"
must work hard to establish, maintain, and grow their dominant
positions.
Framework: four levers of platform
leadership
Based on the companies we studied, we
developed a framework that managers can use to design a strategy for
platform leadership or make their existing strategy more effective.
This framework—which we call the Four Levers of Platform
Leadership—allows platform leaders or wannabes to design and test
the validity of their strategy, given the circumstances of their
industry and the competences of their corporation. Here is an
outline of the four levers:
- Scope of the firm: This lever deals with what the firm
does inside and what it encourages others to do outside. Is it
better for firms to develop an extensive in-house capability to
create their own complements or to let the market produce
complements? Is there a "happy medium" between these two extremes?
If so, when is that the best approach?
- Product technology (architecture, interfaces,
intellectual property): This lever deals with decisions that
platform leaders and wannabes need to make with regard to the
architecture of their product and the broader platform, if the two
are not the same. In particular, they need to make decisions about
the degree of modularity, the degree of openness of the interfaces
to the platform, and how much information about the platform and
its interfaces to disclose to outside firms—potential
complementors who may also become competitors. 7
- Relationships with external complementors: This lever
centers on determining how collaborative versus competitive should
the relationship be between the platform leader or wannabe and the
complementors. Platform leaders and wannabes also need to worry
about how to achieve consensus with their partners, and how to
deal with potential conflicts of interest, such as when the
platform leader decides to enter complementary markets directly
and turns former partners into competitors.
- Internal organization: This lever allows platform
leaders and wannabes to use their internal organizational
structure to manage external and internal conflicts of interest
more effectively. Options include keeping groups with similar
goals under one executive, or separating groups into distinct
departments in order to address potentially conflicting goals with
outside constituencies. The issue of culture and process comes in
here: We found that since innovative, modular industries are often
ambiguous environments, where a complementor today can become a
competitor tomorrow, an internal atmosphere that encourages debate
(or at least tolerates ambiguity) accelerates the strategy
reformulations that are sometimes necessary. At the same time,
efficient internal communication of corporate strategy, once a
decision has been made at the top, facilitates the implementation
of strategic reorientations.
We believe that each of these levers is critical for achieving or
sustaining platform leadership. The Four Levers cover both strategy
formulation and implementation issues, which are intertwined. The
levers are distinct but closely related; therefore, platform leaders
or wannabes need to make choices on these dimensions in a coherent
fashion.
The decision of what complements to make inside and what to leave
to external firms is probably the single most important issue that
platform leaders and wannabes have to decide—and keep deciding. It
is not a onetime event because firms innovate continuously on their
products and add new functionalities that may well have been
performed previously by external firms. This decision encompasses
choosing appropriate levels of investment in venture capital
activities or acquisitions aimed at evolving the platform or helping
the complements business.
Decisions on the architecture or design of the product and on how
to treat intellectual property (i.e., whether to keep product
interface specifications "open" or closed"), tend to have a major
impact on the incentives and ability of external firms to innovate
on complements. And deciding how to treat external firms is, of
course, related to the scope of the firm because it requires a
decision on whether to compete or to collaborate.
We shall also see that platform leaders and wannabes need to be
mindful of the consequences of encroaching on the territory of
developers of complements. There is a strategic trade-off between
systematically entering any complementary market that seems to hold
the promise of profit and maintaining goodwill and collaborative
relationships with developers of complements. While some companies
invest a lot of effort in building a strong reputation for not
encroaching on complementors' turf, others are less careful where
they trample. We shall explain the external circumstances that can
justify these different behaviors and clarify the risks involved
with these two approaches.
We shall also see that platform leaders or wannabes need to
establish an internal organization that supports their objectives.
In particular, when the objective is to maintain collaborative
relationships with complementors, certain organizational design
decisions—such as whether to keep particular groups under one
executive or to separate groups into distinct departments—impact the
ability of a platform leader to convince third parties that it will
not recklessly infringe on their turf. Distinct departments reduce
the fears that third parties might have to invest in complementary
products and new technologies.
The important point here is that platform leaders usually need to
perform a delicate balancing act between competing and collaborating
with complements producers, whose products are necessary to create
demand for the platform. The firms we studied relied on various
means to influence outside firms, ranging from specific technical
choices and organizational decisions to initiatives to enhance their
external relationships and reputations.
