You can create an SvcV-2 just before finishing an OV-2 or in later stages of the architecture just before finishing the SV-1 or SV-2 views.

To create a SvcV-2 diagram

  1. Create Service Specifications and Service Ports.
  2. Associate Service Specifications using Associations.
  3. Associate Service Ports using Service Connectors. 

You can proceed to create SvcV-4 view as soon as the SvcV-2 has been completed.

You can model internal structure of each Service Specification directly in the compartment area of this element shape or using the SvcV-2 Service Resource Flow Internal Description diagram.
