Your slide deck outlines several key entities involved in ICS reviews.<\/p>\n<h2><strong>Business Impact: Key Audit Organizations<\/strong><\/h2>\n<h3><strong><span data-redactor-style-cache=\"font-size: 16px;\">1. DCAA \u2013 Defense Contract Audit Agency<\/span><\/strong><\/h3>\n<p>For Department of Defense (DoD) contracts, DCAA is the primary reviewer of incurred cost submissions.<br \/>\nDCAA examines your:<\/p>\n<ul>\n<li>Direct and indirect costs<\/li>\n<li>Indirect rate calculations<\/li>\n<li>Compliance with FAR Part 31<\/li>\n<li>Supporting documentation<\/li>\n<\/ul>\n<h3><strong><span data-redactor-style-cache=\"font-size: 16px;\">2.
