The design comparison view allows you to compare the structural properties of two UML designs. This is useful in a number of situations.

Comparing subsequent versions of a design. Object-oriented systems are usually developed in an incremental, iterative fashion. After a design phase at the beginning of an iteration, you can compare the current design to the previous iteration:

Comparing design alternatives. If you have modeled alternative solutions to a design problem, the structural properties of the candidate designs can help support the decision which of the alternatives to choose for implementation.
