OPINION: Warehouses of Data Are No Use without Control
Here's an entertaining and instructive story that highlights just how easy it is to let too much data prevent you from seeing the wood for the trees. It concerns Ben & Jerry's, the ice-cream maker now part of Unilever.
Last spring it began to record a noticeable rise in complaints about its popular Cherry Garcia brand; the majority were about the lack of cherries in the product.
