If a control is found to be poorly designed during the planning stage, testing its operating effectiveness becomes redundant because even a well-implemented but poorly designed control will not achieve its intended objectives. The primary focus should be on redesigning the control to ensure it is effective in mitigating risks. Therefore, the auditor should not have proceeded to test the operational effectiveness of a control that was already deemed poorly designed.

The risk assessment process in planning begins with identifying inherent risks (risks without considering controls). The next logical step is to identify and map existing controls to those inherent risks to determine whether they mitigate them effectively. Only after this step can residual risk be assessed. Detecting actual fraud (Option B) is not part of planning. Risk appetite (C) is a management responsibility, not audit's. Option D occurs later after evaluating controls.

According to the International Standards for the Professional Practice of Internal Auditing (Standards) set by the Institute of Internal Auditors (IIA), internal audit functions are allowed flexibility in including consulting engagements in their annual plans. Standard 2010 - Planning states that "the chief audit executive must establish a risk-based plan to determine the priorities of the internal audit activity, consistent with the organization's goals." This risk-based plan should consider the potential value-add of consulting engagements. Consulting engagements that are expected to add significant value or align with strategic objectives are often included, but not all requests need to be automatically included unless they meet these criteria.

Strategic goals are long-term, broad, and mission-driven.
* Options A, B, and C represent short-term operational or tactical goals.
* Option D (carbon neutrality in 5 years) represents a long-term strategic goal.

Job enrichment involves giving an employee more responsibility and control over their work, which increases the employee's sense of ownership and involvement in the task. This concept is about enhancing the role by adding more meaningful tasks and duties to it, rather than simply increasing the quantity of tasks (which would be job enlargement).
This concept can be found in management and organizational behavior theories, such as Herzberg's Two- Factor Theory, which discusses how job enrichment can lead to higher job satisfaction.
