Which test approach provides the GREATEST assurance of the completeness of transactions transferred between systems?
Testing the reconciliations of the totals of transactions in the two systems provides the greatest assurance of the completeness of transactions transferred between systems. This method involves verifying that the total amounts of transactions match in both the originating and the receiving systems, covering all transactions rather than just a sample. This comprehensive approach ensures that all transactions have been transferred completely and accurately, identifying any discrepancies that may indicate issues in the transfer process.
Testing the reconciliations of the totals of transactions in the two systems provides the greatest assurance of completeness because it covers ALL transactions, not just a sample. This approach checks whether the total amounts match in both the originating and the receiving systems. If there are any discrepancies, it highlights that some transactions may not have been transferred completely or accurately. This holistic view of all transactions is more comprehensive and thus provides greater assurance compared to testing only a sample of transactions.
B. Testing a sample of transactions in the source system from a list of all transactions in the destination system: This approach checks if some transactions made it, but doesn't guarantee all originating transactions were transferred. Should be D
This approach involves directly verifying that transactions originating from the source system have been correctly and completely transferred to the destination system. By sampling transactions from the source system and confirming their presence in the destination system, auditors can ensure that the transfer process is accurately capturing all transactions. This method directly assesses the completeness of the transfer by validating that all transactions from the source system are appropriately reflected in the destination system. Therefore, option D offers the greatest assurance of completeness in this scenario.
Answer D is the most effective approach for providing assurance of the completeness of transactions transferred between systems.
