To build a Service Hierarchy model, populate a Service Component definition with the Services that it provides and the Component Category that it belongs to.
1 Create a Service Component Definition.
2 Populate the Category property of the Service Component by adding a Component Category.
3 Add Services to the Service Component definition: either add new Services, or click Choices, and then drag from the choices presented.
4 Create a Service Hierarchy diagram, and then put the Component Category symbols of interest on it.
5 Attach all Component Category symbols to a Business Domain symbol to complete the model.
