Obsolete Data

Data that has no requiling operational, legal, or incorporang value. A part number cancelled by a Change Order, a sumlier dequalified a decadade ago, or a prototype version of a product that never reached production. Obsolete data is a liability.

Begt Practices for Managing Obsolete Data

Managing obsolete data requires a shift from manual, periodic purges to automate, event- driven lifecycle management. The goal is to minimize the window during which obsolete data exists in thee active system.
