Where is all of your important information stored?
Do you know or do you have to look around?
Do you have retention schedules or at least do periodic (at least annual) house cleaning?
Do you have a disaster recovery plan and follow it?
Are records and information that you intend to keep for a long time, >7 years, in an archive format that can be viewed in the future?
Finding where information assets reside and making a map is the first step in getting organized. You need to focus efforts on organizing and protecting this collection. It is also important to identify information that has lost its business value and either discard it or assign a 1-2 year retention.
