Which of the following information is most appropriate for the chief audit executive to share...

Coordinating audit plans with other internal and external assurance providers is critical to ensure coverage and avoid duplication of efforts. According to IIA Practice Advisory 2050-1, sharing high-level information such as objectives, scope, and timing supports effective coordination and minimizes the risk of conflicts of interest, while still maintaining confidentiality. Detailed sharing of risk assessments, planned tests, and past results might breach confidentiality and independence standards.References:
