I have been doing some form of segmentation since the mid seventys. At the begining we just relied on the mathematics used in the segmentation strategy to "profile" the segments. This works fine with scientists and statisticians because they understood the math concepts.
For the last 15 years or so, as I became more involve with delivering segmentation results to a more general audience, I quicly discovered that the sementation profile this audience required need to be more qualitative then quantitative.
We actually employed the skills of people trained in Library Science and Biology to help create descriptive profiling. This special talent, required associating data not used to build the segment to members of a segment (i.e. demographics).
I have found myself and others spending 4 to 5 times the effort defining a profile then it took to do the segmentation itself.
Recently I was forced to do this "profiling" myself. I started to look at the techniques required and found that my quantitative approach was too esoteric for my audience.
