According to the IIA Standards, particularly Standard 2500 - Monitoring Progress, internal auditors are responsible for monitoring the disposition of results communicated to management. They need to assess whether management has taken appropriate action to address audit findings or has consciously accepted the risk of not taking action. The follow-up process is crucial to ensure that identified risks are managed effectively. References: = IIA's Standard 2500 - Monitoring Progress and Practice Guide on Follow-up Processes.

Objectives fall into three categories per COSO:
* Operations objectives: relate to efficiency, effectiveness, and safeguarding of resources.
* Compliance objectives: adherence to laws and regulations.
* Financial reporting objectives: reliability of reporting.
Verifying timely delivery of raw materials relates to operational efficiency, so the correct answer is Operations (A).

To efficiently gather input from a large, geographically dispersed group, a structured survey with scaled responses (B) is most effective. This allows for easy comparison and aggregation of results. Options A and C are less efficient due to open-ended responses, while D is too narrow.

A periodic report from the chief audit executive (CAE) to the board typically includes information about the internal audit activity's purpose, authority, responsibility, and performance relative to the audit plan. This report ensures that the board is kept informed about the internal audit activity's alignment with organizational goals, its independence, and any significant issues or deviations from the plan.
IIA References:
* IIA Standard 2060: Reporting to Senior Management and the Board requires the CAE to report periodically to the board on the internal audit activity's purpose, authority, responsibility, and performance relative to its plan. This standard ensures that the board has a clear understanding of how the internal audit activity is fulfilling its role.
* The Practice Guide on Effective Communication with the Board recommends that the CAE provide regular updates on the internal audit activity's progress against its plan and any significant issues that require the board's attention.

When using the balanced scorecard approach to assess the performance of the internal audit activity, a key performance indicator relevant to the audit client is the percentage of recommendations implemented by the corrective action date. This KPI measures the effectiveness and impact of the audit activity by tracking how well the audit recommendations are being acted upon within the agreed-upon timeframe. It reflects the responsiveness and commitment of the organization to address identified issues and improve its control environment, which is directly relevant to the interests and concerns of the audit clients.
