100% agreed.
I usually use inShort for defining AND implementing processes but it does not limit itself to that and allows for much more productive analysis and uses in day to day work.
Whenever I need to formalize a process or issue it in the organization, I just redraw it using the standard tools and all is good.
Otherwise, inShort would just be useful in designing process and would fall short on its ability to actually roll it out and follow it.
My 2 cents.
