It happens on opportunity after opportunity. A partner commits a named Key Person during teaming, and by the time work starts, that person is booked on three other jobs and will never touch your project. Or the partner cites past performance that sounds perfect, until a single phone call to the reference shows the work was smaller, older, or in a different domain than promised. Or the subject matter expert they staff for proposal writing turns out to have no real depth in the area you need covered.

If you have run enough captures, you have seen all three. And you have probably watched the same thing happen the same way each time, because the teaming phase has a blind spot.

During teaming, much of the focus is on the paperwork – the teaming agreement, the NDA, the workshare split. These matter, and they get careful attention. But too little time is spent checking the thing that decides whether the bid can be delivered: whether the partner can really do what it says it can do.

Partner assessment is not a new idea. Shipley and APMP material both cover it, and most capture guides mention it somewhere. What is rare is seeing it scoped as a defined capture activity, with a named owner, evidence standard, and a decision that changes when the evidence does not show up. The idea is widely acknowledged, and the step is seldom run.

Treat Teaming Like an Acquisition

Here is the reframe that fixes it. Teaming is not a contracting activity. It is an acquisition. You are buying capabilities you do not have, on a deadline, and folding them into a bid you are personally accountable for as prime. Nobody buys a company on the seller’s word alone. They verify. They scale the scrutiny to what is at stake. They put representations and warranties in the deal, with remedies if the seller was wrong. And they keep the right to walk away. Teaming deserves the same discipline, and the payoff is simple: an hour of verification during capture saves you weeks of scrambling during your capture, proposal, or after award. It protects the evaluation score you are bidding to win.

The objection is always time. Proposals are rushed, teaming moves fast, and there is no room for a diligence process. But most of the proof you need is fast to get, if the partner has the goods. A strong partner can produce the person, the rating, and the writing sample in 48 hours. One that stalls is not busy. It is showing you the future.

What to Verify Before You Commit

Here is what to verify, and how to do it quickly.

1. Key Personnel

Get a commitment letter signed by the individual, not just the company. Then spend 30 minutes on a live call with the named person. The bait and switch dies the moment you talk to the human being who is supposed to do the work. Confirm a real availability date and, where it applies, current clearance status. If the partner cannot get you 30 minutes with someone they are proposing as key, you have your answer.

2. Past Performance

Adjectives are not evidence. Ask for the contract number, the agency and the program, the period of performance, the scope and dollar value, the claimed rating, and a reference you can call. Where classification or a proprietary restriction limits what a partner can hand over, ask for what they can share and get the rest from the reference call. Then run the relevance test the evaluation will run: does this work match the factors and the domain in front of you? A strong job in the wrong area may earn little or no credit depending on how the solicitation defines relevance, and you need to know that before you write it into your bid.

3. Proposal Support

Require named people before the teaming agreement is signed, not a promise to assign someone later. Then run the cheapest test in the world. Have your proposed writer or SME spend 20 minutes talking through your real solution or review a short writing sample against the subject at hand. Almost nobody does this, and it catches the mismatch instantly.

4. Capacity

If the partner is carrying meaningful workshare, ask for a bench count of qualified, cleared people, or a concrete hiring plan with a named recruiter and a real pipeline. “We can staff it” is not a plan. A named path to the people is.

5. Standing and Readiness

Capability is one question. Whether the partner is positioned to perform is another. Confirm active SAM registration and a clean exclusions record, any banned equipment representations, CMMC status where it applies, facility clearance and DD-254 flowdown if the work is classified, and accounting system adequacy if the contract is cost type. On any partner carrying real workshare, get a basic read on financial capacity. These checks are quick, mostly public or one question to the partner’s contracts lead, and a buyer confirms them before relying on the capability.

6. Scale the Diligence to the Risk

You cannot run all of this on every partner, and you should not try. Scale the diligence to the risk. A partner carrying major workshare with a scored Key Person gets deep scrutiny. A partner with limited, noncritical workshare, no scored personnel, and no past performance cited in the bid gets a light touch. Matching the effort to how much of the evaluation score and the delivery risk rides on a partner is what keeps this realistic inside a live schedule.

7. Give the Teaming Agreement Teeth

The verification is only half of it. The other half is giving the teaming agreement teeth, and this is where most teaming agreements fall short. Borrow again from how acquisitions are written.

8. Add Representations

The partner formally states that the named person is available and committed, and that the past performance is accurately characterized. If those turn out to be false, that is a breach, not a surprise.

9. Add a Substitution Clause

Any replacement for a named resource must be equally or better qualified and approved by you. Many solicitations carry a key personnel clause that requires advance notice and approval of substitutions after award. Where the solicitation has one, the teaming agreement should mirror it during the proposal, when a quiet swap can cost you points.

10. Add a Trigger and an Off-ramp

If promised resources have not materialized by a defined milestone, you get a remedy: reduced workshare, or the right to remove the partner and bring in a replacement before submission. Knowing you can walk is what gives every earlier conversation its weight.

Move Partner Diligence into Capture

One more point, and it may be the most important. Almost none of this can happen in the proposal crunch, which is exactly why the activity goes missing. People file partner vetting under “proposal,” where there is no time for it. It does not belong there. It belongs in capture, before you commit, while you still have leverage and other partners to choose from. Move it left, and everything above becomes possible.

Moving it left works when the activity has a home. Make partner diligence an exit criterion at the bid decision gate, with a named owner and a one-page summary in front of the gate reviewer: what the bid relies on from each partner, what has been verified and how, what is still open, and what risk the team is accepting by going forward. A gate that sees that page can weigh the risk while there is still time to change partners.

Diligence Should Strengthen the Partnership

A word on the relationship, because someone will raise it. Diligence can feel adversarial, and in a market where good partners have options, pushing too hard can send one to a competitor. The way through is to frame it plainly as mutual protection. A verified partner makes a stronger bid, and a stronger bid is more likely to win, which serves both of you. And notice who bristles. A partner who resists reasonable proof is telling you something useful before you are bound to them.

None of this requires a new process or a new tool. It requires treating teaming for what it is. You are acquiring the capabilities your win depends on. Buy them the way a careful buyer would. Verify before you commit, scale the scrutiny to the stakes, write the deal with teeth, and keep your right to walk. A little rigor up front is far cheaper than the alternative, which you have already paid for more than once.
