UML Abuse

Had a mixed day at work today, good and bad.

The bad today was around a discussion of how we were going to use UML to analyse use cases. All was going well until we got on to discussing how to model the user interface. We need to record the navigation between screens, the decision made was to do this with a mixture of class and statechart diagrams. I argued against this and suggested Visio, but was overridden on the basis that we wanted to do it all in UML via Rational Rose.

Thinking back I realise that I have actually seen this a lot, people determinedly using UML when another style of diagram would have been more appropriate. I seem to recall that Jacobson, Grady and Rumbaugh, when they first wrote up UML, were quite clear that while the diagrams covered the majority of design cases, they by no means covered them all. Where has this attitude gone?

Does anyone else see UML abuse as a problem?
