“Data-mining”, “drilling down”, “insight extraction.” You might think this sounds like an awful lot like hard work and in reality, it is! Getting insights from a customer data set requires a technically skilled analyst ...with a lot of patience…. and a lot of time. The similarities to the lone miner searching for black gold are striking (geddit). The tools may be different (excel rather than a pick axe) but the realities are the same. It is an inefficient way of finding opportunities.
