The best way to determine whether IT investments are meeting business objectives is to compare the realized return on investment (ROI) versus the projected ROI (Option B). This approach measures actual performance against planned expectations.
ISACA CISA Reference: The ISACA IT Governance framework emphasizes performance measurement through ROI analysis, ensuring IT investments align with strategic objectives.
Risk Implication: If actual ROI is lower than projected, this may indicate ineffective investment decisions, poor execution, or misalignment with business goals.
Alternative Choices:
Option A: Break-even analysis only determines when an investment recoups its costs but does not measure performance against business objectives.
Option C: Budgeted versus actual spend assesses financial discipline but does not indicate business impact.
Option D: Industry average ROI provides benchmarking but does not assess internal goal achievement.

The best evidence of an IT strategy correction's effectiveness is the synchronization of IT activities with corporate objectives. The IT strategy correction is a process of reviewing and adjusting the IT strategy to ensure that it aligns with and supports the corporate strategy and objectives. The synchronization of IT activities with corporate objectives means that the IT activities are consistent with and contribute to the achievement of the corporate goals and vision. The IS auditor can measure and evaluate the IT strategy correction's effectiveness by comparing the IT activities with the corporate objectives, and assessing whether they are aligned, integrated, and coordinated. The other options are not as good evidence of an IT strategy correction's effectiveness, because they either do not reflect the alignment of IT and business, or they are inputs or outputs of the IT strategycorrection process rather than outcomes or results.

The most important consideration for a go-live decision when implementing an upgraded enterprise resource planning (ERP) system is the business case. The business case is the document that defines and justifies the need, value, feasibility, and risks of the project. It also outlines the expected costs, benefits, outcomes, and impacts of the project. The business case provides the basis for measuring and evaluating the success of the project. Therefore, before deciding to go live with an upgraded ERP system, it is essential to review and validate the business case to ensure that it is still relevant, accurate, realistic, and achievable.
A rollback strategy, test cases, and post-implementation review objectives are not the most important considerations for a go-live decision when implementing an upgraded ERP system. These are important elements of project planning, execution, and evaluation, but they are not sufficient to determine whether the project is worth pursuing or delivering. These elements should be aligned with and derived from the business case.

The correct answer is B. Management's commitment to information security. Management's commitment to information security is the most critical factor for the success of an information security program, as it provides the leadership, support, and resources needed to establish and maintain a secure environment.
Management's commitment to information security can be demonstrated by:
Setting the vision, mission, and goals for information security, and aligning them with the organization's strategies and objectives1.
Establishing and enforcing the policies, standards, and procedures for information security, and ensuring compliance with relevant laws and regulations1.
Allocating sufficient budget, staff, and technology for information security, and investing in training and awareness programs2.
Promoting a culture of security within the organization, and engaging with stakeholders and partners to foster trust and collaboration2.

An organization outsourced its IS functions. To meet its responsibility for disaster recovery, the organization should coordinate disaster recovery administration with the outsourcing vendor. This is because the organization remains accountable for ensuring the continuity and availability of its IS functions, even if they are outsourced to a third party. The organization should establish clear roles and responsibilities, communication channels, testing procedures, and escalation processes with the outsourcing vendor for disaster recovery purposes. The organization should not discontinue maintenance of the disaster recovery plan (DRP), as it still needs to have a documented and updated plan for restoring its IS functions in case of a disaster. The organization should not delegate evaluation of disaster recovery to a third party or internal audit, as it still needs to monitor and review the performance and compliance of the outsourcing vendor with respect to disaster recovery objectives and standards.
