I did some research to figure out what icons exist for decision support, and which of those represents the decision support the best. I didn't find any suitable icons, because I think they don't represent the "support" aspect, and are not widely used: the user can not understand what the icon means.
These two seem to be useful:
But both are too complex for me, and don't represent the workflow decision, like this:
But the last one is also not understandable for a regular user.
Does anyone have a good idea for a decision support icon? My goal is to represent that a software helps to classify incoming measured data, make a decision and track the decision's consequences.
