 The auditor’s next course of action should be to evaluate the appropriateness of the remedial action taken by the auditee. The auditor should assess whether the alternative approach taken by the auditee is effective, efficient, and aligned with the audit objectives and recommendations. The auditor should also consider the impact of the change on the audit scope, criteria, and risk assessment. Conducting a risk analysis incorporating the change, reporting results of the follow-up to the audit committee, and informing senior management of the change in approach are possible subsequent actions that the auditor may take after evaluating the appropriateness of the remedial action taken. References: CISA Review Manual (Digital Version): Chapter 1 - Information Systems Auditing Process

IT value analysis is a process of measuring and demonstrating the contribution of IT to the organization’s goals and objectives. An IS auditor should be concerned about the lack of IT value analysis, as it may indicate that the IT investments and resources are not aligned with the business needs and expectations, or that the IT performance and outcomes are not monitored and evaluated. The other options are less critical findings that may not have a significant impact on the IT governance. References:

The best way to prevent accepting bad data from a third-party service provider is to implement business rules to reject invalid data. Business rules are logical statements that define the data quality requirements and standards for the organization. By implementing business rules, the organization can ensure that only data that meets the predefined criteria is accepted into the enterprise data warehouse. Obtaining error codes indicating failed data feeds, purchasing data cleansing tools from a reputable vendor, and appointing data quality champions across the organization are useful measures to improve data quality, but they do not prevent accepting bad data in the first place. References: ISACA Journal Article: Data Quality Management
