The impact if corrective actions are not taken is the most important factor to consider when scheduling follow-up audits. An IS auditor should prioritize the follow-up audits based on the risk and potential consequences of not addressing the audit findings and recommendations. The other options are less important factors that may affect the timing and scope of the follow-up audits, but not their necessity or urgency. References:

 Providing security certification for a new system should include an evaluation of the configuration management practices prior to the system’s implementation. Configuration management is a process that ensures that the system’s components are identified, controlled, and tracked throughout the system’s lifecycle. Configuration management helps to maintain the security and integrity of the system by preventing unauthorized or unintended changes. End-user authorization to use the system in production is not part of security certification, but rather a post-implementation activity that grants access rights to authorized users. External audit sign-off on financial controls is not part of security certification, but rather a verification activity that ensures that the system complies with financial reporting standards. Testing of the system within the production environment is not part of securitycertification, but rather a validation activity that ensures that the system meets the functional and performance requirements. References:

 Incremental backups are backups that only copy the data that has changed since the last backup, whether it was a full or incremental backup. The main reason to use incremental backups is to minimize the backup time and resources, as they require less storage space and network bandwidth than full backups. Incremental backups can also improve key availability metrics, such as recovery point objective (RPO) and recovery time objective (RTO), but that is not their primary purpose. Reducing costs associated with backups and increasing backup resiliency and redundancy are possible benefits of incremental backups, but they depend on other factors, such as the backup frequency, retention policy, and media type. References: CISA Review Manual (Digital Version): Chapter 5 - Information Systems Operations and Business Resilience

This is the most helpful method for measuring benefits realization for a new system, because it involves evaluating the actual outcomes and impacts of the system after it has been implemented and used for a certain period of time. A post-implementation review can compare the actual benefits with the expected benefits that were defined in the business case or the benefits realization plan, and identify any gaps, issues, or opportunities for improvement. A post-implementation review can also assess theeffectiveness, efficiency, and satisfaction of the system’s users, stakeholders, and customers, and provide feedback and recommendations for future enhancements or changes.

The other options are not as helpful as post-implementation review for measuring benefits realization for a new system:

Function point analysis. This is a technique that measures the size and complexity of a software system based on the number and types of functions it provides. Function point analysiscan help estimate the cost, effort, and time required to develop, maintain, or enhance a software system, but it does not measure the actual benefits or value that the system delivers to the organization or its users.

Balanced scorecard review. This is a strategic management tool that measures the performance of an organization or a business unit based on four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard review can help align the organization’s vision, mission, and goals with its activities and outcomes, but it does not measure the specific benefits or impacts of a new system.

Business impact analysis (BIA). This is a process that identifies and evaluates the potential effects of a disruption or disaster on the organization’s critical business functions and processes. A BIA can help determine the recovery priorities, objectives, and strategies for the organization in case of an emergency, but it does not measure the benefits or value of a new system.
