The usual notion of differentiation is a way of understanding the infinitesimal behaviour of a map, i.e. the map restricted to ever decreasing scales. However there are elements of the differentiation process that make sense at larger scales as well. I will discuss the utility of this view point in the work of Eskin-Fisher-Whyte on quasi-isometries of the 3 dimensional solvable group and some subsequent generalization.
