EXHIBIT 10.7 OVERLAPPING DOMAINS
functionality. Overlapping business domains are common, and their intersected sections reveal
commonalities between business entities in an organization. These shared zones, as depicted in
Exhibit 10.7??”the investments domain and the small-business domain??”may contain mutual services
and other service-oriented assets such as infrastructure or middleware enabling technologies.
Their overlapping regions may also introduce organizational reusability and asset consolidation
opportunities. Chapter 11 introduces modeling opportunities that can leverage common functionalities
of domain structures. This overlapping domain structure would enable practitioners not
only to find software asset reuse opportunities, but also identify business execution redundancy
that should be consolidated.
BUSINESS DOMAIN GEOGRAPHIC BOUNDARIES
Business domains depend on their environments and their natural habitats. Domains are driven
by their underlying technologies and are influenced by their physical environments. Compare, for
example, two mutual fund investment domains, owned by the same company and residing on
different continents??”North America and Europe. Would their hosting environments treat them
differently? Would U.S. and Canadian government regulations and compliance rules apply to the
European domain?
Geographic boundaries can also impose technological hurdles.
