Engineers vs. Artists

UML has 2 problems:

1) It has everything, including the kitchen sink, in it. This makes for a big complicated application that is hard to learn.

2) UML doesn't enforce a work flow from design to code. It fact it has no direct decomposition into code the way a structured design would.

The main problem is the tendency for developers to be programmers instead of software engineers. The mindsets are different: one is death-or-glory/John Wayne type of person and the other makes solid dull code that works and knows how to handle things when it didn't work (BSOD anyone?)
