The engagement supervisor should encourage the auditor to improve communication skills. Effective communication is essential for internal auditors, especially in ensuring that process owners have the opportunity to respond to and clarify any issues raised in the draft audit report. This collaboration helps ensure that the audit findings are accurate and that any misunderstandings or errors are resolved before the report is finalized. Encouraging better communication also helps build a positive relationship between the audit function and the audit clients.

To provide effective governance over the organization's culture, the organization's governing body should provide direction. This involves setting a tone at the top that promotes ethical behavior, accountability, and transparency throughout the organization. Providing direction helps ensure that organizational values are communicated and reinforced, influencing the culture and ethical climate of the entire organization.References: IIA guidance on governance and leadership's role in organizational culture.

Assessing soft controls can help internal auditors in undertaking root-cause analysis because soft controls, such as corporate culture and employee behavior, often provide insights into the underlying causes of observed deficiencies. By evaluating these soft controls, auditors can identify why certain hard controls may be failing and what might be influencing employee actions and attitudes, thus facilitating a more effective audit.References: The Institute of Internal Auditors (IIA) guidance on behavioral and cultural audits and risk management practices.

In this situation, the appropriate action for the internal auditor is to remain independent and avoid roles that could impair this independence, such as making managerial decisions. By advising and then directing the management to submit the proposal to senior management and the board, the auditor maintains an advisory role without crossing into decision-making territory, thus preserving the independence necessary for an assurance role.References: Institute of Internal Auditors (IIA) - International Standards for the Professional Practice of Internal Auditing

When a risk assessment shows that the cost of addressing a particular risk is greater than the perceived benefit, the appropriate risk response approach is to accept the risk. Risk acceptance means acknowledging that the risk exists but deciding not to take any action to mitigate it, usually because the cost of mitigation is higher than the potential impact. This approach is a rational decision when the risk is deemed to have a low likelihood or impact, or when other controls are considered sufficient.
