You use a simple tagging language to identify workspace objects as members of functional, structural, or other types of groupings. After you set up these groupings, you can chart them in EV or “black-box” them in the Diagrammer.
Each member of a grouping is identified by a tag, "Payroll," for example. Each grouping can, in turn, reference a more inclusive grouping, "HR," for instance. The figure below shows the tag hierarchy for a typical enterprise:
In fact, this is the default tag structure that ships with EA. The "Enterprise" tag is the root of the structure. The "Finance," "HR," and "Sales" tags represent departments in the enterprise. The "Accounting," "Payroll," and "CRM" tags are the applications owned by the departments.
