FAR Part 15 keeps source selection tied to stated criteria
For negotiated federal acquisitions, the documented decision must compare proposals against the solicitation's criteria and explain the business judgments behind tradeoffs.
Editorial figure by Procurement Technology Current. Source context: U.S. Federal Acquisition Regulation — Part 15, Contracting by Negotiation.
Configuration begins with the solicitation
A sourcing platform can offer flexible scoring, artificial-intelligence summaries, and reusable templates, but a negotiated federal acquisition is bounded by the issued solicitation. FAR Part 15 states that proposals and their relative qualities are evaluated solely on the specified factors and subfactors. The configured evaluation model therefore needs traceable lineage to that source.
Buyers should test how the product imports or creates factors and subfactors, locks the approved version, controls weights and scoring rules, and handles amendments. Every evaluator should see the applicable version, and the record should show when a change became effective. A convenient hidden criterion or post hoc scoring adjustment can undermine the decision even if the arithmetic is correct.
The authority must exercise independent judgment
The FAR assigns the source selection decision to the source selection authority and requires independent judgment. Decision-support technology may organize proposal content, surface evidence, compare evaluations, or draft a starting narrative. It should not obscure whose judgment controlled or present generated language as an unexplained conclusion.
A credible workflow preserves evaluator inputs, conflicts and reconciliations, access controls, advisory outputs, the authority's edits, approvals, and the final record. Where automation ranks or summarizes content, the system should expose the underlying proposal evidence and configuration so a qualified user can verify the result. The acceptance test is reviewable decision support, not autonomous selection.
Tradeoffs need reasons, not just scores
FAR Part 15 requires documentation of business judgments and tradeoffs, including the benefits associated with added costs, while not requiring those tradeoffs to be quantified. That distinction matters for product design. A score table may be useful, but it does not by itself explain why one proposal's evaluated benefit justified a premium or why another advantage did not.
Buyers should ask the system to construct a comparative assessment across all stated criteria and link each material judgment to proposal evidence and evaluator reasoning. The final narrative should retain exceptions, dissent, and revisions rather than collapsing the record into a single unexplained rank. Cost, price, technical, past-performance, and risk information need their governed context.
Test an amendment and a tradeoff
A bounded proof can use a synthetic solicitation with multiple factors, an amendment, two proposal revisions, and a best-value tradeoff. The provider should show version control, evaluator assignments, access boundaries, discussions or clarifications where applicable, final proposal revisions, comparative assessment, source citations, authority review, and an exportable decision record.
FAR Part 15 is a legal framework for contracting by negotiation; it does not endorse a procurement platform or determine the correct procedure for a particular acquisition. Contracting officers, counsel, and acquisition leadership must set the applicable process. The product decision is whether the tool supports that process without introducing unstated criteria or hiding the rationale.
Enterprise buyer test
Translate this change into the exact population, record type, workflow stage, decision owner, effective date, and evidence that could be affected. Ask current or prospective providers to demonstrate the named workflow with representative data and an exception—not a polished feature tour. Record what official documentation establishes, what a provider states, what the team observes, and what remains unresolved.
A defensible review also identifies the dependency outside the product. Authority interpretation, policy configuration, data quality, integrations, human judgment, approval rights, release governance, training, and retained evidence may remain customer or service responsibilities. The evaluation should preserve those boundaries instead of treating a technology claim as the complete operating model.
What we will watch next
Procurement Technology Current will watch the named source and affected market records for later evidence that changes status, scope, availability, implementation timing, workflow consequence, or the limits of the initial report. A later announcement does not silently overwrite this dated account; the change ledger preserves the sequence.
