Your mission partners mean well, but that brand name justification they handed you probably needs some work. Learn what to look for, what questions to ask, and when a sole source actually makes sense.
Your job is not to rubber-stamp what the customer sends you. Your job is to evaluate whether the justification actually holds up. Here is how to do that.
In operational contracting, you receive J&As with your packages regularly. Mission partners are domain experts who understand what they need. They have done the legwork, determined their requirements, and tried to justify a specific approach.
A brand name J&A says "we need this specific product from this specific manufacturer, and nothing else will work." That is a high bar to clear.
The first thing you do when you receive a brand name J&A is walk the customer back through their reasoning.
How did they get to that determination? What market research did they do? Did they look at alternatives? Did they talk to other vendors?
Is this company really the only one who can supply this? Or did they just Google it, find one company, and call it a day?
Is it truly a brand name requirement, or is it a performance requirement that happens to be met by one brand they know about?
Many times the customer found one vendor that works and stopped looking. That is not a justification. That is convenience.
There are legitimate reasons to restrict competition. The key is whether the justification actually supports the restriction.
Substantial duplication of costs. If the Government has an existing system built around a specific manufacturer's components, and switching would require replacing the entire infrastructure, that is a real justification.
Proprietary interfaces and data rights. If the manufacturer owns the technical data and nobody else can legally produce the item, competition is not possible.
Safety and interoperability requirements. Genuine limitations that cannot be met by alternatives are legitimate grounds.
The justification needs to explain WHY, not just WHAT. "We need Brand X" is not a justification. "We need Brand X because our existing system uses proprietary connectors that only Brand X manufactures, and replacing the system would cost $2M with no operational benefit" is a justification.
"This is what we have always used" - not a justification.
"The vendor is local" - not a justification.
"We already have a relationship with them" - not a justification.
No market research documented at all.
The J&A was clearly written by the vendor - you can tell.
The justification describes a brand name but the actual requirement could be written as a performance specification.
The Air Force uses a simplified single source justification form for acquisitions under the simplified acquisition threshold. This is the template you will see most often when customers bring you a brand name buy at the base level. It has five sections:
Section A: General Contract Information. The basics: contracting activity, project name, PR number, and estimated cost. Nothing to evaluate here, just make sure it matches the package.
Section B: Description of the Supplies/Services Required. What are they buying? This should be clear enough that someone unfamiliar with the requirement can understand it.
Section C: Justification for Soliciting from a Single Source or Brand Name. This is where the real evaluation happens. The customer needs to explain WHY this specific source or brand name is necessary.
Section D: Efforts to Obtain Competition. What did they do to look for alternatives? Did they check SAM.gov? Did they contact other vendors?
Section E: Steps to Preclude Future Single Source or Brand Name Awards. What will they do differently next time to allow competition?
Check the J&A Examples tab to see how this looks on paper, and how it falls apart when done wrong.

A fire department sends you a single source justification for 15 Motorola APX 8000 portable radios at $6,800 each ($102,000 total). The justification states:
Section C: "We need Motorola APX 8000 radios because they are the best radios on the market and our firefighters are already trained on them. Motorola is the industry standard for public safety communications."
Section D: "We checked Motorola's website for pricing."
Section E: "We will continue to purchase Motorola radios as they become available."

A calibration lab submits a single source justification for 30 Fluke 80PK-27 temperature probes at $89 each ($2,670 total). The justification states:
Section C: "The Fluke 80PK-27 probe uses a proprietary SureGrip connector interface that mates directly with our Fluke 287 and Fluke 289 True-RMS multimeters. These multimeters use a banana plug/thermocouple socket combination unique to Fluke's design. Third-party K-type thermocouple probes require an adapter (Fluke P/N 80AK) that introduces measurement error of +/- 0.5 degrees C, which exceeds the 0.3 degree tolerance required by our PMEL calibration procedures (TO 33K-1-100-2)."
Section D: "Searched SAM.gov on 3 Feb 2026. Searched GSA Advantage on 4 Feb 2026. Contacted Omega Engineering (555-0177) and Extech Instruments (555-0234), neither of whom manufactures a probe with the proprietary Fluke connector. See attached emails."
Section E: "When the multimeters reach end of life (estimated FY29), replacement specifications will require standard K-type thermocouple interfaces to enable competitive probe sourcing."

The communications squadron submits a single source justification for 8 Cisco Catalyst 9300 switches at $9,200 each ($73,600 total). The justification states:
Section C: "Our network infrastructure is built on Cisco IOS-XE. All 47 existing switches are Cisco Catalyst series. Adding a different manufacturer's switches would require a separate management platform, separate training for network administrators, and separate spare parts inventory. Per the attached cost analysis, maintaining a dual-vendor environment would cost an additional $185,000 over three years in licensing, training, and support contracts versus $73,600 for Cisco replacements."
Section D: "Searched SAM.gov and GSA Advantage on 10 Jan 2026. Contacted Juniper Networks (555-0312) and Aruba/HPE (555-0287) for compatibility assessments. Both confirmed their switches can operate in a Cisco environment but require additional management software. See attached correspondence."
Section E: "The base network modernization project (programmed FY29) will evaluate open-standard network architectures that do not require single-vendor lock-in."
