SDR

Definition

SDR (System Design Review) is a technical review assessing whether a system design satisfies requirements. Part of the defense acquisition lifecycle milestones.

Where this matters in federal contracting

SDR is a step or workflow in the federal-procurement lifecycle. Knowing where SDR fits in the larger acquisition arc — from market research through award through performance — helps contractors time their engagement, identify the right contracting officials, and avoid showing up too late to influence the requirement. Many proposal failures trace back to misunderstanding when SDR occurs, who owns it, and what artifacts it produces. The related terms above name the adjacent process steps that most commonly precede or follow SDR, and tracking those transitions over time is one of the more reliable ways to build pipeline visibility ahead of formal solicitations.
