Exhibit 1.7 illustrates the four major reasons for the transformation of a solution service
into an analysis entity: (1) granularity alignment, (2) reusability enhancement, (3) functionality
redundancy reduction, and (4) solution reevaluation.
From Solution to Design Service. A solution service should be reverted back to its design state
if a contract with its corresponding consumer is about to be modified. More specifically, this
transformation should take place if requirements dictate modification to a service??™s collaboration,
interaction, and integration with its peer services and subscribing consumers. This alteration
of service behavior obviously can influence the coexistence conditions in a service community.
???Behavior,??? for that matter, is associated with business or technical functionality activities managed
and executed during transactions. This includes frequency of message delivery, coordination
of message transmissions, reaction to message requests and responses, management of service
availability, and even the method by which a service manages allowable consumption rates.
The following three major conditions suggest redesign of a solution service:
