A.  What is a SSDD?

The SSDD is the SSA's written record documenting the rationale to justify and explain the award decision.  This "single summary" document reflects the SSA's comparative assessment and decision and includes the rationale for any business judgments - tradeoffs made or relied on by the SSA - including benefits associated with additional costs.  The SSDD supports selection of the best value proposal consistent with the stated evaluation criteria.  It clearly explains the decision and documents the reasoning used by the SSA to reach the decision.  When reading a well written, stand alone SSDD, an individual should understand why the SSA made the decision.
