A second method for determining whether a problem is attributable to the operator or the system
After correcting or temporarily patching the problem, another method that should be considered is to have another operator recreate the problem and test it on another workstation. This will allow verification that the problem can be recreated on other machines.

Next, have the operator recreate and test the problem against the original machine to verify that the problem can be created and fixed, and to see if any other issues arise with the effected workstation. Having the operator follow the documentation that was originally created for the problem will verify if other operators are following the standard operating procedures as well.
