Can Tipping Points Be Measured?

I was thinking today that if statistical sampling is valid, and adoption rates for new products can be measured in small areas, is there a way to use that to model tipping points with a reasonable degree of accuracy? I think one of the most difficult things in launching a new venture is to know when to change. Have you given it enough time, are you near a tipping point, or are you on the wrong path? Sometimes if you are growing, but slowly, it is tough to figure that out.

You are a bunch of smart people. If you know of any work along these lines, please point me in that direction.
