During an audit of a reciprocal disaster recovery agreement between two companies, the IS auditor would be most concerned with the allocation of resources during an emergency. A reciprocal disaster recovery agreement is an arrangement by which one organization agrees to use another's resources in the event of a business continuity event or incident. The IS auditor would need to ensure that both parties have clearly defined their roles and responsibilities, their resource requirements, their priority levels, their communication channels, and their escalation procedures in case of a disaster. The IS auditor would also need to verify that both parties have tested their agreement and have updated it regularly to reflect any changes in their business environments. The frequency of system testing is not as critical as the allocation of resources during an emergency, because system testing can be performed periodically or on demand, while resource allocation is a dynamic and complex process that requires careful planning and coordination. The differences in IS policies and procedures are not as critical as the allocation of resources during an emergency, because both parties can agree on common standards and protocols for their disaster recovery operations, or they can adapt their policies and procedures to suit each other's needs. The maintenance of hardware and software compatibility is not as critical as the allocation of resources during an emergency, because both parties can use compatible or interoperable systems, or they can use virtualization or cloud computing technologies to overcome any compatibility issues.

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.
