Benefits of Coordinating Activities

  • For External Auditors (EA):
  • More Insight: Gain a comprehensive view of audit processes and risk areas.
  • Improved Client Relations: Encourages collaboration and trust with clients.
  • For Internal Auditors (IA):
  • Identifying Areas for Investigation: Enables IA to focus on areas of concern highlighted by EA.

  • Engagement Client Staff:
  • Relationships based on mutual trust ensure relevant and useful information is shared with IA.
  • External Auditor:
