Domain Model with Superimposed World Diagram
for WUIM

Decide on the entities in the WUIM world and capture them in a domain model expressed as a collection of rectangles, one for each entity, as shown on Slides 13, 14, 16, and 19 of the slides about the Requirements Engineering Reference Model.

Then divide these entities into the environment and the system. Superimpose this division on domain model diagram. You can do this superimposition by drawing a shape enclosing the environment entities and another shape enclosing the system entities; then label each shape as ENV or SYS as the case may be, as was done on the blackbord in class when Slide 13 of the slides about Requirements Engineering Reference Model was shown. Alternatively, you could just mark each domain model entity with ``ENV'', ``SYS'', or both, as the case may be.

If you have done this superimposition correctly, you should be able to see clearly which entities are in the interface.
