During a pre-deployment assessment, the best indication that a business case will lead to the achievement of business objectives is that the business case reflects stakeholder requirements. A business case is a document that explains the rationale, benefits, costs, and risks of a proposed project or initiative. A business case should align with the strategic goals and vision of the organization and address the needs and expectations of the stakeholders who are involved in or affected by the project12.
Stakeholder requirements are the conditions or capabilities that stakeholders expect from a project or its outcomes. Stakeholders can include customers, users, employees, managers, suppliers, regulators, and others who have an interest or stake in the project. Stakeholder requirements should be identified, analyzed, prioritized, validated, and documented throughout the project lifecycle34.
The business case should reflect stakeholder requirements because they provide the basis for defining the project scope, objectives, deliverables, quality standards, success criteria, and benefits realization. By reflecting stakeholder requirements, the business case can demonstrate how the project will add value to the organization and its stakeholders, justify the investment and resources required for the project, and facilitate the decision-making and approval process for the project5 .
Therefore, during a pre-deployment assessment, an IS auditor should look for evidence that the business case reflects stakeholder requirements as the best indication that the business case will lead to the achievement of business objectives.

Comprehensive and Detailed Explanation:
System exception and deviation reports are the most effective tools for identifying abnormal events, as they highlight deviations from expected processing and performance.
* Logs (A): Provide raw data but require manual review or monitoring tools.
* Operator problem reports (C): Capture issues but depend on human reporting, which may miss critical events.
* Operator work schedules (D): Related to staffing, not abnormal events.

The best recommendation is to align the IT strategy with the business objectives. This will ensure that the IT projects and initiatives are consistent with the organization's vision, mission, and goals. IT strategy should be derived from and support the business strategy, not the other way around. By aligning the IT strategy with the business objectives, the organization can achieve better value, performance, and alignment from its IT investments.
Reviewing priorities in the IT portfolio (option B) is not the best recommendation, as it does not address the root cause of the misalignment between the IT strategy and the IT portfolio. The IT portfolio should reflect the IT strategy, which in turn should reflect the business objectives. Simply changing the priorities in the IT portfolio without aligning the IT strategy with the business objectives may result in suboptimal or conflicting outcomes.
Changing the IT strategy to focus on operational excellence (option C) is also not the best recommendation, as it may not be aligned with the business objectives. The organization's IT strategy should be based on its competitive advantage, market position, customer needs, and industry trends. If the organization's business strategy is heavily focused on research and development, then changing the IT strategy to focus on operational excellence may not be appropriate or beneficial.
Aligning the IT portfolio with the IT strategy (option D) is also not the best recommendation, as it does not address the misalignment between the IT strategy and the business objectives. Aligning the IT portfolio with the IT strategy may improve the coherence and consistency of the IT projects, but it may not ensure that they are aligned with the organization's vision, mission, and goals.
Therefore, option A is the correct answer.
