FIGURE 13.2 Four Common IS Governance Designs

business units control over their own applications by decen-
tralizing the governance of these IS resources. A more
customizedhybrid design is found especially in large, multi-
divisional firms in which some business divisions choose to
have a centralized IS unit handle all of their IT needs, while
other divisions choose to have a federal or decentralized
design in order to have more local control of their own IT
resources, which might even include having their own IS
staff running their own computers. Customized designs are
also common in companies that have acquired other firms,
and then allow them to continue to operate as autonomous
business units or subsidiaries.
Some organizations with centralized designs may
also operate as a “business within a business” where the IS
unit is treated much like an external vendor, with separate
cost and revenue accounting, and an agreed-upon transfer
pricing scheme. Some senior business managers believe
that this is the best way to hold both the IS and business
units accountable for IT costs for both IT service delivery
and new IT applications. In large organizations, a common
approach is to also combine the IS organization with other
functional support organizations (e.g., human resources,
legal, physical facilities maintenance, transportation) into a
shared servicesunit, which may or may not be created as
a separate legal entity. Shared services organizations dedi-
cated to different world regions may also be set up to sup-
port large multinationals, and sometimes these regional
units even compete with each other. (See the box “Shared
Services at a Multinational Firm.”)


How does a firm choose among these IS governance designs?
A firm’s IS governance design needs to be aligned with char-
acteristics of the overall business. If a company is relatively
small, a centralized IS design is most likely. If a company is
large and has multiple business units, and the heads of these
business units operate with a high degree of autonomy, then a
federal or decentralized design may be a better choice. If
some business leaders within a large firm are reluctant to be
responsible for governing IS resources, then a custom design
may be adopted to accommodate business unit preferences.

MANAGING IT SERVICE DELIVERY
The physical technology assets of an organization (e.g., its
computer hardware, software, telecommunications and
data networks) have always represented a very large capi-
tal investment. Although hardware costs have decreased
even as their capabilities have increased, organizational
demands for computing processing power, data storage,
and communications speed and user demands for desktop
PCs, laptops, and other portable devices have also
increased. From a businessperspective, these technology
assets are used to deliver a service—such as access to an
enterprise system screen for entering order information or
a printer connected to a local area network.
Today, employees at all levels in the organization, at
multiple locations, typically interact with the computer
network for essential aspects of their work. Thus, network
or computer failure now has a high degree of visibility—it
