Source Selection Plan (SSP)
A Source Selection Plan (SSP) documents how a competitive negotiated acquisition will be evaluated and decided: the organization of the evaluation team, the factors and subfactors, their relative importance, and the methodology for reaching an award decision.
The SSP is written before the solicitation goes out and governs everything after proposals arrive. It establishes the source selection authority, evaluation board structure, rating method, and the factors — technical, past performance, price — that the RFP's Sections L and M must mirror exactly. Divergence between the SSP, the solicitation, and the actual evaluation is a classic protest-sustainer.
DoD source selections follow the DoD Source Selection Procedures, which prescribe standard rating scales and documentation requirements beyond the FAR baseline.
Regulatory Reference

RFO Status
Model deviation text for FAR Part 15 issued September 30, 2025 rewrites contracting by negotiation, and DoD Source Selection Procedures still apply on top; verify both against your agency's adopted text before drafting.
