6. What is "Double Entry Double Compare"?

This method is used for more accuracy demanding clients. Two data entry operators (A & B) key in the data and generate the output files: File A & File B.

A QC operator (C) compares these two files through the compare software. When it shows any discrepancy between the two files, C duly corrects the mistakes and generates File C.

Another QC operator (D) compares these two files through the compare software. When it shows any discrepancy between the two files, D duly corrects the mistakes and generates File D

The final QC operator (E) compares File C and File D. When it shows any discrepancy between the two files, E duly corrects the mistakes and generates the final File E.

For printed matter source documents, an accuracy level of 99.995% can be achieved through this process.
