| Task: Model Task Services |
 |
 |
|
| Services that provide task-specific business logic.may not be highly reusable but are often composed as part of an orchestrated service, and are therefore useful to model as services. |

Initial service candidate model for this task service is created. The focus of this task is on services contained in choreograpy models that are not entity or utility type services. This is logic that includes business rules, conditional logic, exception logic, etc. This business logic may be implemented in rules, procedural code, scripting languages, etc. If the business logic is best expressed as business rules, then reference should be made to the associated Rule List. These task services do not include the high level processes themselves, which are orchestrations implemented in orchestration language such as BPEL.
If this task service candidate needs to coordinate (compose) the use of other previously identified
services in order to meet its processing requirements, that composition (which can also be described as a
collaboration) is also modeled in this task. |

Analyze the services in the choreography model that remain after eliminating entity and utility application services.
Add other task service candidates and their candidate tasks to the service candidate model / list / repository
Associate business rules.
For task service candidates whose business logic has been described using business rules, specify the associate reulste list and perform the Analyze Business Rules Task
|
| Task services represent business process specific logic. |
