Source Selection Authority (SSA)

The Source Selection Authority (SSA) is the official designated by the agency to make the final award decision in a negotiated procurement, reviewing evaluation board results and issuing a written source selection decision documenting the rationale for selecting the winning proposal.

What is the Source Selection Authority?

The SSA is the single individual responsible for the award decision in a competitive negotiated procurement. Under FAR 15.303, the contracting officer is the SSA for most procurements unless the agency designates a higher-level official due to the program's size, complexity, or strategic importance.

For major programs, the SSA may be:

• A Program Executive Officer (PEO) for large defense programs
• A Senior Procurement Executive for very large civilian agency acquisitions
• An Assistant Secretary for politically sensitive or high-value procurements

The SSA's responsibilities include:

• Reviewing SSEB results: Reading and understanding the technical, management, and past performance evaluation ratings with supporting rationale
• Conducting the best value tradeoff: Independently assessing whether paying a premium for higher technical quality is justified by the specific benefits documented in the evaluation
• Issuing the Source Selection Decision Document (SSDD): Writing the formal decision that explains in detail why the selected offeror's proposal represents the best value to the government
• Signing the contract award: Authorizing the contracting officer to make the award

The SSA is not required to agree with the SSEB's ratings or the SSAC's recommendation, the SSA has independent decision-making authority. However, the SSA must document the rationale for any deviation from SSEB conclusions, and that rationale must be supported by the evaluation record.

The SSDD is a critical document because it is the primary record reviewed in a bid protest. If the SSDD does not adequately explain the award decision with reference to the evaluation record, the award is vulnerable to protest.

Why the SSA matters for government contractors

Understanding the SSA designation tells you something about how strategically important the procurement is to the agency. An SSA who is a senior program official brings a programmatic perspective that may weight technical risk reduction more heavily than a contracting-officer SSA who focuses on price. During proposals and discussions, some companies research the SSA's background and priorities, a former program manager as SSA may value schedule performance highly; a former finance official may weight cost control more heavily. Post-award, the SSDD is the most important document to obtain through a debriefing, it tells you exactly how the SSA characterized your proposal and the winning proposal.

Example

On a $500 million DoD information management contract, the designated SSA is the Program Executive Officer for Enterprise Information Systems, a two-star general with 25 years in military IT. After the SSEB rates Company A (Outstanding Technical, $480M) and Company B (Good Technical, $440M), the SSAC recommends Company B for cost savings. The SSA reviews the evaluation record independently and determines that Company A's Outstanding rating reflects a validated technical risk reduction methodology worth approximately $75M in anticipated change order costs over the contract life. The SSA awards to Company A, documenting the specific technical findings that justify the $40M price premium.

Frequently Asked Questions

Is the SSA the same as the contracting officer?

For most procurements, yes, the contracting officer serves as the SSA. For large, complex, or strategically significant procurements, agencies designate a more senior official as SSA, with the contracting officer continuing to manage the procurement process. When a separate SSA is designated, this is typically disclosed in the solicitation.

Can the SSA change the evaluation ratings before making the award decision?

The SSA cannot change evaluation ratings, that is the SSEB's role. However, the SSA can disagree with the SSEB's interpretation of findings, can weight findings differently in the best value tradeoff, and can request that the SSEB reconsider a rating if the SSA believes an error was made. The SSEB then issues revised ratings if warranted.

How soon after FPR evaluation is the source selection decision made?

There is no regulatory timeframe. For simple competitions, the SSDD may be signed within a few weeks of FPR evaluation completion. Complex procurements may take months. Legal review of the SSDD adds time. The agency has an obligation to act with reasonable diligence to avoid unreasonable delay protests.

Is the source selection decision document available to unsuccessful offerors?

Yes, in redacted form. Unsuccessful offerors who request a debriefing are entitled to see the evaluation results for their own proposal and the overall award rationale. Competitors' specific ratings and proposal details are redacted. The SSDD summary is typically the centerpiece of a debriefing presentation.
