When an organization's enterprise architecture (EA) department decides to change a legacy system's components while maintaining its original functionality, there are several factors that an IS auditor should consider when reviewing this decision. However, the MOST important consideration is likely to be the current business capabilities delivered by the legacy system.
Explanation:
A. The current business capabilities delivered by the legacy system: This is the MOST important consideration for an IS auditor because it relates directly to the organization's overall business objectives. The auditor should evaluate whether the proposed changes align with the organization's current business capabilities, processes, and workflows. They should also consider whether the changes will affect the system's ability to deliver the intended business value.
B. The database entity relationships within the legacy system: While this is an important consideration, it is not as critical as the current business capabilities delivered by the system. An IS auditor should assess whether the proposed changes will affect the system's ability to manage data effectively and ensure data integrity, but this is secondary to the system's overall ability to deliver business value.
C. The data flows between the components to be used by the redesigned system: This is an important consideration, but it is not as critical as the current business capabilities. The auditor should evaluate whether the proposed changes will affect the system's ability to manage data flows effectively, but this is secondary to the system's overall ability to deliver business value.
D. The proposed network topology to be used by the redesigned system: While network topology is an important consideration, it is not as critical as the current business capabilities delivered by the legacy system. The auditor should assess whether the proposed changes will affect the system's network performance, scalability, and security, but this is secondary to the system's overall ability to deliver business value.
In summary, an IS auditor should prioritize evaluating whether the proposed changes align with the organization's current business capabilities, processes, and workflows when reviewing the enterprise architecture department's decision to change a legacy system's components while maintaining its original functionality.
