a base object model that reflects business needs and how they should be
supported by the solution. This provides some “straw-man” classes that
the Object Interaction Diagrams can be developed from.
work needs to be performed. If not done as a separate task, it will be
done as a part of the Object Interaction Diagrams. Performing this task
prior to the Object Interaction Diagrams provides a more consistent and
well thought out approach to both the object model and the Object Interaction
Diagrams. Not performing this work prior to Object Interaction Diagrams
permits objects to be developed relative to a specific function instead
of cross functional and is therefore more less flexible.
