Sources Sought

What is a sources sought notice and how might I know to respond to one?

A sources sought notice is a market research announcement. A government agency asks industry to identify itself and describe its capability before any solicitation exists, and the responses directly determine whether the eventual contract goes to small business as a set-aside.

A sources sought notice is a market research announcement. A government agency asks industry to identify itself and describe its capability before any solicitation exists. The responses directly determine whether the eventual contract goes to small business as a set-aside.

It is not a solicitation, and no award can result from it. It is nonetheless one of the highest-leverage documents in the federal market.

Why it matters more than it looks

FAR 19.502-2 states the "Rule of Two." It applies to an acquisition above the simplified acquisition threshold. It requires a small business set-aside when the contracting officer has a reasonable expectation of both of the following:

  • Offers will be obtained from at least two responsible small business concerns.
  • Award will be made at fair market prices.

Sources sought responses are the primary evidence for that determination. Two small businesses that respond capably can convert a full-and-open competition into a small business set-aside. The absence of qualified responses is exactly how a requirement stays unrestricted. A decision not to respond is a decision about the competitive field you will later face.

The second reason to respond is to shape the requirement. At the sources sought stage the agency is still writing it. Feedback has a real chance of changing the eventual solicitation. Useful feedback covers scope and an unrealistic delivery schedule. It also covers a specification that only one vendor can meet, or a labor category mix that does not match the work. After the RFP drops, that window has closed.

Related notice types

Federal opportunity notices carry a type, and the type tells you what stage the acquisition is in.

  • Sources sought. Market research to identify capable sources.
  • Presolicitation notice. Advance warning of a solicitation.
  • Request for information (RFI). Broader industry input, sometimes on approach or technology rather than on sources.
  • Special notice. Industry days and pre-proposal conferences.

All four are pre-solicitation intelligence. By the time the solicitation or combined synopsis/solicitation appears, the agency has largely fixed the requirement.

What a good response contains

  • Your business information. Legal name, UEI, CAGE code, socioeconomic certifications, and the NAICS codes under which you qualify as small.
  • A direct capability statement mapped to the stated requirement. Not a generic corporate brochure. Address the specific tasks the notice describes, in the vocabulary of the notice.
  • Relevant past performance. Contracts of similar scope, size and complexity. Give enough detail (agency, value, period, your role) for the government to judge relevance.
  • An honest self-assessment of size status under the applicable NAICS code. That status is the fact the Rule of Two turns on.
  • Answers to whatever questions the notice asks. Many notices include specific questions, and many responses ignore them.
  • Constructive feedback on the requirement, where you have something real to say.

Respect the format constraints. Sources sought notices frequently impose a page limit, and agencies commonly discard a response that exceeds it without reading it.


The mistake that makes this term matter

A sources sought notice does not look like an opportunity. There is no solicitation number to bid, no due date that costs you anything to miss, and nothing to win. It arrives in the same feed as the real opportunities, and it asks for unpaid work: a capability statement, written to an outline somebody else wrote, for a requirement that may never get funded. So it goes to the bottom of a list that is always long.

Months later the same requirement appears as a full-and-open RFP, and the company that skipped the notice bids against primes many times its size. Nothing went wrong in the procurement. The contracting officer looked for a reasonable expectation of two capable small businesses, found one response, and recorded what the evidence supported. The companies that answered decided the competitive field, before a solicitation existed to compete for.


What goes wrong in practice

The response is a capability brochure. A contracting officer who must decide whether two small businesses can do this specific work cannot extract that from a general marketing document. Map your capability to their task list explicitly.

Teams assert size status loosely. Small business status turns on the size standard for the specific NAICS code the procurement assigns. Some codes use receipts and others use employees. A loose assertion undermines the response and can create representation problems later.

Nobody responds, and then everyone complains. A requirement that goes out unrestricted after a sources sought notice drew one response drew exactly the outcome the process exists to produce.

Responders over-share proprietary detail. Sources sought responses generally do not carry the protection that proposals carry, and the government may release portions of them. Describe capability. Do not hand over your approach.

The window is short. Agencies often allow only a week or two, and they rarely extend it.

What to do

  1. Monitor sources sought and presolicitation notices in your NAICS codes as actively as solicitations.
  2. Respond to anything genuinely within your capability.
  3. Map the response to the stated scope, and keep it inside the stated format.
  4. Contact the technical point of contact where the notice permits it.
  5. Compare the eventual solicitation against the sources sought notice.
  6. Read the changes as evidence of who else responded and what they said.

The acquisition is still malleable at the notice stage. That is the reason to watch this stage as closely as you watch the solicitations themselves.

What a sources sought notice is not

It is not a solicitation, and it is not a request for pricing. A response creates no obligation on either side.

It is also not a guarantee that a procurement will happen at all. Agencies issue many notices for requirements that never get funded. And a strong response earns no preference in the eventual competition. The benefit is in shaping the field and the requirement, not in earning credit.

This term, read against your solicitation.

A definition tells you what the words mean. What decides the bid is whether your company clears the requirement behind them, and that is a question about your registrations, clearances and past performance, not about vocabulary.
