Hi Folks:

Lots of people don't think visually. Some people like Use Case Models, or
step-by-step written instructions. Others use more complex diagramming
formalisms. My favourite is stock-and-flow diagramming because I can
simulate and calibrate my model with Vensim.

The folks in the world of Agile Modelling discuss this often. The best
process modelling technology is speech.

Iteratively. You write it, try it out, and fix it at the point of
failure. Repeat. :-)

Lots of garbage appears in poorly-constructed flowcharts, too.
