Having an independent party review the source calculations provides an additional layer of validation and assurance. This helps ensure the accuracy and integrity of the calculations by having someone separate from the original creator verify the logic, formulas, and assumptions used in the calculations. Independent reviews can help identify errors, inconsistencies, or potential risks in the calculations, reducing the likelihood of unintended modifications causing issues. Overall, independent review adds accountability and improves the quality of the calculations in end-user computing environments.

Having an independent party review the source calculations is a crucial control measure to ensure accuracy and reliability. Independent review can help identify errors, omissions, or unintended modifications made by the original creator of the EUC. It provides an objective assessment and can help catch mistakes that may not be apparent to the creator. In summary, while all these measures may contribute to risk mitigation, having an independent party review the source calculations is the most effective way to reduce the risk of unintentional modifications in complex calculations in end-user computing.
