<Object-oriented sub-systems should be described using a class diagram. If classes or interfaces are used across sub-systems, make sure you mention this in the description of the class diagrams. If your system entails layers, make sure you indicate this in the class diagram, e.g. by means of packages. For each class diagram, make sure you also mention the deployment artifact (from the deployment diagram) it is part of.>

<Provide sequence diagrams for major object interactions within the sub-system. It is ok if sequence diagrams cross sub-system boundaries. Make sure you explain this in the description of the diagram. Sequence diagrams must be consistent with the class diagrams described above. Also, if sequence diagrams cover interaction with users, make sure the diagrams are consistent with SDDs you may have documented as part of the SRS.>
