Post-Implementation Review Procedure

A.

The implementation of intelligent-agent software for granting loans to customers is a significant development for any organization. The IS auditor should perform a post-implementation review to evaluate the effectiveness and efficiency of the system and ensure that it complies with relevant laws, regulations, and internal policies.

Among the given options, the KEY procedure for the IS auditor to perform would be A. Review input and output control reports to verify the accuracy of the system decisions. Here is the detailed explanation of why this option is the correct choice:

Intelligent-agent software is designed to perform tasks on behalf of users, such as making decisions or taking actions based on predefined rules and data analysis. In the case of granting loans, the software would use predefined rules, algorithms, and data analysis to determine whether a loan application meets the organization's lending criteria and should be approved or rejected.

However, the accuracy of the system's decisions depends on the quality and completeness of the input data and the logic and accuracy of the algorithms used in the system. Therefore, the IS auditor should review the input and output control reports to verify the accuracy of the system's decisions.

Input control reports would include information about the data that the system uses to make decisions, such as loan application information, customer data, credit scores, and other relevant data. The IS auditor should review these reports to ensure that the data is accurate, complete, and relevant to the lending decisions.

Output control reports would include information about the decisions made by the system, such as approved and rejected loan applications, loan amounts, interest rates, and other relevant data. The IS auditor should review these reports to ensure that the system's decisions are accurate, consistent, and comply with relevant laws, regulations, and internal policies.

In summary, reviewing input and output control reports is the KEY procedure for the IS auditor to perform during the post-implementation review of intelligent-agent software for granting loans to customers. This procedure helps to ensure the accuracy and completeness of the system's decisions and compliance with relevant laws and policies.
