When you have a computerized readout of WHAT SHOULD BE THERE it gives you something with which to reconcile the actual count. When the computer says you should have more than the physical count shows it is called "SHRINKAGE". Or as is sometimes true the value of what people stole from you.
In the olden days before computers. there were TWO COUNTS. The first one would be the benchmark that the second count should match. If it didn't that would require a 3rd count. Oy vey! So computers have materially affected for the better the taking of inventory. What else has the computer materially affected for the better in your opinion? What has it irreparably damaged?
