Abstract

The progressive tracking of items in relation to other items as they are processed and transformed through a sequence of processes executed in a workflow procedure intended to produce a finished hard copy document product for transport to a destination location, as a result of a production run, enables permission based control of one or more processing steps during the production run and/or effective scheduling of any re-do operations that may be desired upon detection of any discrepancies in the item processing operations.
