The internal audit activity should not be responsible for identifying and prioritizing CSR issues, as this task typically falls under the purview of senior management or a dedicated CSR team. Internal audit's role is to provide assurance and consulting services to ensure the effectiveness and efficiency of the organization's operations, including CSR initiatives. Consulting on project design and implementation, serving as an advisor on internal controls, and evaluating the effectiveness of CSR efforts are all activities that fit within the internal audit’s scope of work.
