The idea is that by observing people (and their businesses), you'll see choke points that software would solve. For a taco truck, maybe the owner is writing down quantities of ingredients (shells, salsa, meat, etc.) on a physical piece of paper. Once he's low, he calls up the supplier to order more.

A software solution might keep let him keep track of this on an iPad, and perhaps even integrate order forms (so he can order stuff immediately from the iPad).
