The primary reason an IS auditor reviews an organization chart is to better understand the responsibilities and authority of individuals.

Explanation
Conducting periodic testing and incorporating lessons learned is the best way to improve the effectiveness of an incident response team. This allows the team to practice their response procedures, identify any gaps or weaknesses in their response, and learn from their mistakes. It also helps to keep the team's skills sharp and up-to-date. The lessons learned from these tests can then be used to improve the team's procedures and performance12. While understanding information systems technology, disseminating incident response procedures, and publishing KPI metrics can contribute to the effectiveness of the team, they do not provide the same level of continuous improvement as periodic testing and learning from experience.

Explanation:
One of the main objectives of an audit is to identify potential risks; therefore, the most proactive approach
would be to identify and evaluate the existing security practices being followed by the organization. IS
auditors should not prepare documentation, as doing so could jeopardize their independence. Terminating
the audit may prevent achieving one of the basic audit objectives, i.e., identification of potential risks. Since
there are no documented procedures, there is no basis against which to test compliance.
