Double Data Entry
  • The data entry job is divided into batches and each batch of document has a covering "Keying Specification Instruction Sheet".
  • Two data typists enter the data in different files to generate the output say A & B.
  • These two files are electronically compared through software. The program stops where it finds and mismatch between the two files giving the operators the opportunity to correct the mistakes. This type of comparison is done by two operators to generate the output files say C & D.
  • The two files (C and D) are again electronically compared to generate the file say E.
  • The text file (E) is audited to check the required accuracy level of 99.995%.
  • The data file generated is copied on CDs and couriered to client. Simultaneously, the data files are also transferred onto the Internet FTP site on a daily basis.
