Thanks for the comments.

We do seem to agree on most of the benefits of modeling. When I talked about creating 100% semantically complete models, I was talking about executable UML models — not code generation. It is possible to create models that are immediately executable and I have been using this approach for the past few years to develop business applications. You can see references to some examples in the previous comments.

However, as you pointed out, picking the right amount of and types of models is important. Key is to use just enough models to impart executable semantics to the target domain. For example, in the platform I worked with used only class diagrams (to capture business objects) and activity diagrams (to capture business processes) to create a fully functioning application from the models.
