Step 8: Correct Current Data Errors

Business Benefit and Context

The correction of current data errors is an exciting milestone in the information and data quality improvement process. However, for continuous improvement it is important not only to correct current data errors, but also to prevent future ones. Larry English strongly recommends that data correction activity should be a “one-time event only, coupled with process improvement to prevent occurrence of those defects” (1999).
