To discover the causes of errors, so that the causes can be eliminated.The saying about the rotten apple in the barrel applies here. Get it out of the barrel before it spoils more apples. Put more emphasis on prevention than cure. When an inventory error is discovered, not only fix the record but—what’s far more important—eliminate the cause of the error. Was the cause of the error an inadequate procedure, insufficient security, a software bug, or perhaps incomplete training of a warehouse
person? Whenever practical, find the cause of the error and correct it so that it doesn’t happen again.
