When communicating the results of the quality assurance and improvement program (QAIP) to senior management and the board, the chief audit executive (CAE) must include disclosures on the "Scope and frequency of both the internal and external assessments." This information provides stakeholders with insight into the comprehensiveness and timing of the QAIP evaluations, ensuring transparency and accountability in the internal audit function's efforts to maintain or improve quality and effectiveness.
IIA Standard 1312 - External Assessments

The best step for the chief audit executive (CAE) to take when determining that the internal audit activity lacks adequate independence is to request that the board restructure the reporting line to ensure the CAE has unrestricted access to the board. This action will help to enhance the independence and objectivity of the internal audit activity by ensuring that the CAE reports functionally to the board, which is a key aspect of maintaining organizational independence.
The IIA Standards: Standard 1110 - Organizational Independence: "The chief audit executive must report to a level within the organization that allows the internal audit activity to fulfill its responsibilities. The chief audit executive must confirm to the board, at least annually, the organizational independence of the internal audit activity." IIA Practice Guide: "Independence and Objectivity": Discusses the importance of reporting lines and organizational structure in maintaining the independence of the internal audit activity.

The feedback from operational management highlights a lack of effective communication. While the internal audit team effectively communicated the audit findings, they failed to adequately consider and integrate management's input on resolving the issues. Improving communication skills would help the internal audit team to better engage stakeholders throughout the audit process and integrate their perspectives into the audit recommendations effectively.
The Institute of Internal Auditors (IIA) - Competency Framework for Internal Auditors

According to IIA guidance, the chief audit executive should review the quality assurance and improvement program of the internal audit activity progressively on a day-to-day basis. This continual review ensures that the internal audit activity remains effective and aligned with the organization's objectives and adheres to professional standards, thereby maintaining and enhancing the value provided by the audit function.
IIA standards related to the quality assurance and improvement program, which advocate for ongoing monitoring to ensure the effectiveness of the internal audit activity.

The scenario describes a substantial increase in cancelled proposals, which could indicate fraudulent activity.
One potential fraud risk scenario is that some electricians might be offering clients reduced fees if they pay with cash, leading to off-the-record transactions. This can result in the cancellation of official proposals and lost revenue for the company, as these transactions might not be recorded in the company's financial systems.
This type of fraud involves bypassing the formal processes and price lists, which impacts the integrity of the procurement and sales processes.
