Critical
High
Normal

A large amount of valuable information in an organization has often accumulated over time into hard-to-find and manageable unstructured data — excels, text documents, intranet pages, or emails.

Once this information has been identified, a determined effort can be made to minimize its amount.Important data outside data systems is subject to one of the following decisions:

  • move into a data system
  • get rid of (when the information is old, no longer necessary or otherwise irrelevant)
  • is kept in use and a responsible person is appointed to manage the risks
