A side comment: My current company sells to enterprises. Out of curiosity, last year I tried to look at the usage patterns of customers who left (and stayed). I had a simple hypothesis: those who didn't use the software regularly were the most likely to leave. Surprisingly, this had no correlation. It was another reminder, that in enterprise sales, low or high usage patterns are sometimes not a predictor of customer retention. It obviously depends on the industry, but sometimes it has as much to do with internal politics, salesmanship, and other things that are simply outside the scope of your code.
