I agree that agile and MDA are just two different tools in the toolbelt, part of the stuff I'm working on are to reduce the impedance mismatch between the various aspects (IA, design, code) and faciliate easy change, as even the best models may dash against the side of a road on a curve nobody could see. Bring ducktape and a ruler ;) http://troyworks.com/blog/?p=22#respond Good post.

These all highlight a really important angle of modelling -- using models as useful conversational playthings, rather than as static representations of a "perfect" world. A model drawn on a whiteboard has some interesting aspects that a model in a document lacks:

* it has a “semantic soundtrack”: as the model is drawn, an explanation is nearly always given with it.

* it unfolds in time: as someone draws and talks, the model appears in stages that make sense, rather than appearing all at once.

* it is communal: anyone in the conversation can walk up to it and change it

* it has a dead-simple user interface and zero cost, in contrast to most modelling software tools.

These all highlight a really important angle of modelling — using models as useful conversational playthings, rather than as static representations of a “perfect” world.
