Section: The process of Auditing Information System

Explanation
Root cause is the most important thing for an IS auditor to determine and understand to develop meaningful recommendations for findings. A root cause is the underlying factor or condition that leads to a problem or issue. A finding is a statement that describes a problem or issue identified during an audit. A recommendation is a suggestion or advice that aims to address or resolve a finding. To develop meaningful recommendations for findings, an IS auditor should determine and understand the root cause of each finding, as this can help to identify the most effective and appropriate actions to prevent or correct the problem or issue. The other options are not as important as determining and understanding the root cause, as they do not directly address or resolve the finding. References: CISA Review Manual, 27th Edition, page 434

The role of an IT steering committee is to ensure that the IS department is in harmony with the organization's mission and objectives. To ensure this, the committee must determine whether IS processes support the business requirements. Assessing proposed additional functionality and evaluating software stability and the complexity of technology are too narrow in scope to ensure that IT processes are, in fact, supporting the organization's goals.
