Big Data is growing at a rapid pace and with Big Data comes bad data. Many companies are using Business Intelligence to make strategic decisions in the hope of gaining a competitive advantage in a tough business landscape. But bad data will cause them to make decisions that will cost their firms millions of dollars.

According to analyst firm Gartner, the average organization loses $8.2 million annually through poor Data Quality, with 22% estimated their annual losses resulting from bad data at $20 million and 4% put that figure as high as an astounding $100 million. Yet according to the Experian Data Quality report, 99% of organizations have a data quality strategy in place. This is disturbing in that these Data Quality practices are not finding the bad data that exists in their Big Data.
