Who manages customer data? It’s marketing at about one-third of the companies polled by DataIQ for the UK Royal Mail. Two-thirds cited a central data organization or IT. (Multiple answers were allowed so at some companies it’s both, and/or other groups including CRM and customer service.) Rather shockingly, one-third (32.7%) had no formal data quality process and 16.3% don’t validate internal data at all. Lots of other interesting data, including estimates of how much bad data harms the bottom line.
