A. B. C. D.D.
The best course of action for an IS auditor to verify that a released application system is providing value to the organization would be to perform a gap analysis against the benefits defined in the business case. Therefore, the correct answer is D.
Explanation:
A gap analysis involves comparing the actual performance of a system to the expected or desired performance. In this case, the benefits defined in the business case are the expected or desired performance of the system. By performing a gap analysis, the IS auditor can determine if the system is delivering the expected benefits, which is a good indicator of the value the system is providing to the organization.
Reviewing the results of compliance testing (option A) may provide information on whether the system is compliant with relevant laws and regulations, but it may not provide information on the value the system is providing to the organization.
Quantifying improvements in client satisfaction (option B) may provide some indication of the value the system is providing, but it may not be the best course of action since client satisfaction may not directly translate to organizational value.
Confirming that risk has declined since the application system release (option C) may be an important consideration for the organization, but it does not necessarily provide direct evidence that the system is providing value to the organization.
Therefore, option D, performing a gap analysis against the benefits defined in the business case, is the best course of action for an IS auditor to verify that a released application system is providing value to the organization.
