I realize that the cost of finding these problems can be enormous, too. It can help to have some industry expert help. I would recommend that you purchase and read any of the several excellent books that Thomas C. Redman has written. These books focus on the data quality problems and have some facts and figures on average cost of poor quality data to business. For more in-depth and technical treatments of data quality management issues I would direct you to books written by Jack Olson and Larry English.
