Errors and omissions can be minimized through good input form design. Detect errors and irregularities so they can be reported and corrected. Source Data Collection and Entry Establish that data input is performed in a timely manner by authorized and qualified staff. Correction and resubmission of data that were erroneously input should be performed without compromising original transaction authorization levels. Where appropriate for reconstruction, retain original source documents for the appropriate amount of time. Accuracy, Completeness and Authenticity Checks Ensure that transactions are accurate, complete and valid. Validate data that were input, and edit or send back for correction as close to the point of origination as possible. Processing Integrity and Validity Maintain the integrity and validity of data throughout the processing cycle. Detection of erroneous transactions does not disrupt the processing of valid transactions. Output Review, Reconciliation and Error Handling Establish procedures and associated responsibilities to ensure that output is handled in an authorized manner, delivered to the appropriate recipient, and protected during transmission; that verification, detection and correction of the accuracy of output occurs; and that information provided in the output is used. Transaction Authentication and Integrity Before passing transaction data between internal applications and business/operational functions (in or outside the enterprise), check it for proper addressing, authenticity of origin and integrity of content. Maintain authenticity and integrity during transmission or transport.
