Part 2 — Executive Summary (Milestone 2)

Purpose

The executive summary is for non-technical leadership. It should:

• Fit on one page


• Explain overall risk posture


• Highlight critical issues


• Recommend immediate actions


• Avoid technical jargon

Executive Summary Template

# Executive Summary
