In a piece entitled “Mistaken Identity Resolution Part V: Identity Resolution vs. Data Quality” that was posted May 28th of last year, we said that a “Gartner study done several years ago estimated that poor quality customer data costs U.S. businesses an estimated $611 billion dollars a year.” We thank Ted Friedman  and Mark Beyer at Gartner for recently pointing out that the estimate actually came from a 2002 TWDI study by Wayne Eckerson entitled “Data Quality and the Bottom Line.”
