12 FEDERATED BUSINESS DOMAIN INTEGRATION ENVIRONMENT
Unfortunately, time-to-market aspects, in the short run, may not benefit from asset reusability
strategies. Indeed, an autonomous business tier structure can leverage commonly utilized
services that serve dispersed tiers that do not maintain a close relationship. But the priorities of
independent business units may dictate otherwise. Therefore, reusability and functionality redundancy
are not the burning issues when integrating services with unstructured business models.
Exhibit 10.13 illustrates autonomous tiers integration environments. Note that some tiers
maintain communications with their peers. However, this general scheme does not support a high
degree of business tier collaboration.
DISTRIBUTED CLUSTER TIER STRUCTURE. A group of tiers that share common business attributes
is named a business cluster structure. Such a collection typically maintains intercommunication
and business dependencies that collectively contribute to an organization??™s objectives. This integration
environment structure is akin to an isolated computer network that maintains a certain
level of autonomy and forms relationships between its internal partner nodes.
For example, a business clustered environment can be composed of tiers linked to carry out
core product execution, such as a variety of retirement investments or a collection of individual
loan programs.
