Responding to McNeile... ... That is what a traditional Domain Model does. However, an executable OOA model only models the software portion. [BTW, this is my...
Below is a message I posted to Scott Ambler's Agile Modeling Group. I have (so far) had no reply. I was wondering if anyone in this group could help. Ashley ...

Responding to Mark T... ... Yes, there seems to be a major risk. Recently there was an issue of IEEE Software that had five short pieces, including one by...
Are the IEEE Software articles on UML 2.0 you mention available on the web? I suppose that, if UML aims to be "descriptive" rather than "prescriptive" (i.e.,...

Responding to McNeile... ... Actually, I miscited; sorry about that. They were in the ACM Communications about 2-4 months ago. Sorry about that. I know that...
I just finished reading Executable UML and was unable to determine the justification for one of its design decisions. Most state machine executives I have...
Hello Caitlin - ... No. I'll let Steve and/or Marc respond more fully why they chose only Moore notation for the book, but in general simplification is a good...
... I'll post a second message after this one that summarizes our rationale behind the simple Moore state machine (actions on states) approach. ... A state...
In the Executable UML book we model object lifecycles using state machines in which the action is executed upon entry to the state. These are known as Moore...
IMO, actions on transitions and actions on states are both necessary, but appropriate in different circumstances. Take the example of a Bank Account. The...
Responding to Bestler... Let me add an additional spin to what Balcer and Fontana said WRT why Moore is used. There is an aesthetic problem with the Mealy...

... I can see how a "decision state" can be implemented as a state with actions that *always* produce a signal to self. But this strikes me as considerably...
