This document explains how the DSA conducts assurance. It is subordinate to DSA 01: The DSA Sub-Operating Model and complements the other documents in the DSA 01 series. Together, the 01 series provides people in the DSA, and across defence, an understanding of how the DSA conducts its activity and what can be expected from its outputs.
