According to IIA guidance, the chief audit executive (CAE) is required to report the results of ongoing monitoring and periodic quality assessments to both senior management and the board at least annually. This ensures transparency and allows for any necessary actions to improve the quality and performance of the internal audit activity. References: The IIA's International Standards for the Professional Practice of Internal Auditing (Standards), specifically Standard 1311 - Internal Assessments, Standard 1320 - Reporting on the Quality Assurance and Improvement Program, and Standard 1312 - External Assessments.

The most helpful metric to measure the success of an internal audit activity in providing risk-based assurance is the percentage of highly significant risks covered by the internal audit plan. This demonstrates that the internal audit function is focusing its resources on the most critical areas that could impact the organization's objectives, ensuring that significant risks are being addressed and managed appropriately. This alignment with the organization's risk profile is a key indicator of effective risk-based auditing.

2010 - Planning, and Standard 2120 - Risk Management.

According to IIA guidance, a new internal auditor is expected to possess a broad understanding of IT risks and controls. This competency is crucial because:
* IT risks and controls are integral to the overall control environment and impact all areas of an organization.
* Knowledge of IT risks and controls enables auditors to assess the effectiveness of controls over information systems, data security, and technology infrastructure.
* As technology evolves, internal auditors must understand how to evaluate IT-related controls to provide relevant assurance and advisory services.
While technical industry-specific expertise, cybersecurity expertise, and forensic accounting knowledge are valuable, they are not core competencies expected of every new internal auditor according to IIA guidance.
The fundamental requirement is a solid grasp of IT risks and controls.

Segregating duties between code development and migrating changes into production is a critical control to prevent fraudulent activities by developers. This control ensures that no single individual has the ability to develop code and deploy it to the production environment without oversight. Key benefits include:
* Reducing the risk of unauthorized or malicious code changes.
* Ensuring that changes are reviewed and tested by a different team before deployment.
* Increasing accountability and transparency in the software development lifecycle.
By implementing this control, organizations can prevent developers from committing fraud or making unapproved changes to the ERP system, thereby protecting the integrity and security of the system.

Workshops are likely the most efficient way for management to self-assess the overall effectiveness of the controls in a 200-person manufacturing department. Workshops can facilitate interactive discussions and group activities that help identify control gaps, understand employee perspectives, and consolidate feedback effectively across a large group.References: Best practices in internal control assessments and organizational development literature.
