Unplanned recoveryA recovery is referred to as "unplanned" when there was no planned barrier, such as a checkpoint in the work process, to "catch" the error.
Example: A driver and passenger approach a washed out road. There is no roadblock, but an observant passenger sees the washed out road and yells, "Look out!"
The recovery resulted from an accidental catch, not a planned barrier, such as a roadblock; therefore the recovery was unplanned.
