Latest / The Buyer's Side with Fexingo: Procurement, Sourcing, and B2B Purchasing Decisions / How One Buyer Used Red Teaming to Uncover Supplier Weaknesses
Transcript
- Lucas: So there's this procurement manager I came across recently — Sarah Chen at a mid-sized electronics firm. She walked into a critical supplier negotiation and, instead of just reviewing their standard audit docs, she had her team run something closer to a military-style red team exercise before the meeting. Luna: Red teaming — like, simulate the other side's playbook? In procurement? Lucas: Exactly. Sarah had a hunch the supplier was being a little too optimistic about their production capacity. So she pulled together a team from engineering, finance, and quality — people who don't normally join a negotiation pre-brief — and told them, 'Your job is to be the supplier. Defend their claims. Find every hole in our own assumptions.' Luna: And did they find anything? Lucas: They found that the supplier's claimed capacity of 50,000 units per month was actually closer to 35,000, because the supplier was leasing a key piece of equipment that had already been repossessed by the lessor. That detail never surfaced in any formal audit. The supplier had been patching together production through a single subcontractor without telling anyone. Luna: Wow — so the red team basically uncovered a hidden single point of failure. Lucas: Exactly. Sarah went into the negotiation with that knowledge. She didn't lead with it — she let the supplier make their usual pitch about capacity and reliability. Then she asked a few pointed questions about the leased equipment and the subcontractor. The supplier realized she knew more than they expected. Luna: I imagine that shifts the power dynamic pretty dramatically. Lucas: It does. She ended up getting a 10 percent price reduction and a contractual requirement that the supplier maintain a qualified backup for that subcontractor within 90 days. Without the red team, she might have agreed to the original terms and discovered the capacity gap later, during a production crunch. Luna: So when does red teaming make sense for a typical procurement team? Not every negotiation needs that level of prep. Lucas: Right. Sarah herself says she reserves it for high-stakes situations — sole-source suppliers, critical components, or suppliers whose claims feel too rosy. It's also useful when you're entering a new market or a new relationship where you don't have years of history to draw on. The key is to treat it as a structured exercise, not a fishing expedition. Luna: And you need the right people on the team — people who aren't afraid to challenge assumptions. Lucas: That's the hardest part. Most organizations are culturally allergic to internal conflict. Sarah had to hand-pick people who could separate the role from the relationship. She told her team, 'We're not attacking the supplier. We're stress-testing our own plan.' That framing made all the difference. Luna: It's interesting — we've talked a lot on this show about supplier collaboration and trust. Red teaming seems almost like the opposite. How do you keep it from damaging the relationship? Lucas: That's a fair point. Sarah's approach was to use the red team findings internally to shape her strategy, not to ambush the supplier. She shared the capacity issue as a joint problem — 'Hey, we both want a reliable supply chain. Let's fix this together.' The supplier actually appreciated that she caught it before it became a crisis. Luna: So it's not about being adversarial — it's about being prepared. Lucas: Exactly. And that's a mindset that takes practice. Speaking of practice — these conversations are part of how we, at Fexingo, try to help people think more strategically about their work. We deliberately don't run ads on these shows — it keeps the focus on ideas, not interruptions. If you find that valuable, and you want to support that choice, there's a link at buy me a coffee dot com slash fexingo. It's a simple way to say 'this matters' without any pressure. Luna: Yeah, it really does help us keep going. And on that note — back to red teaming. What's the biggest mistake buyers make when they try this? Lucas: The biggest mistake is treating it like a one-time event. Sarah runs red team exercises periodically, even when there's no immediate negotiation. She'll pick a key supplier and run a two-hour session where the team tries to identify what could go wrong. It builds the muscle of adversarial thinking so that when a real negotiation comes, the team is ready. Luna: So it becomes part of the procurement toolkit, not just a crisis response. Lucas: Exactly. And the tools themselves don't have to be complex. Sarah uses a simple framework: three columns — 'what the supplier claims,' 'what we suspect,' and 'what we can verify.' The red team's job is to populate the third column. Sometimes they find nothing. But often, they find something that changes the whole conversation. Luna: I wonder how many procurement teams are actually doing this. I've been in rooms where people just accept the supplier's data at face value. Lucas: Not enough. A survey from the Institute for Supply Management a couple years ago found that less than 20 percent of procurement organizations use any kind of adversarial simulation. That means 80 percent are going into high-stakes conversations with only the information the supplier chose to share. Luna: That's a huge blind spot. So what's the first step for a team that wants to try this? Lucas: Start small. Pick one supplier where you have a moderate level of concern — maybe a single-source supplier with no backup. Invite three people from different functions. Spend 90 minutes listing every assumption you're making about that supplier's operations, finances, and reliability. Then ask each person to bring one piece of evidence that could challenge each assumption. Luna: And if you find nothing, that's also useful — it builds confidence in the relationship. Lucas: Exactly. Sarah says her team's confidence in their supplier relationships actually improved after red teaming, because they knew they weren't being naive. There's a big difference between blind trust and verified trust. Luna: Verified trust — I like that. Any final advice for someone who's about to try this? Lucas: Yeah — don't keep the results to yourself. Share the general findings with the supplier in a constructive way. Sarah wrote a one-page summary for her key suppliers that said, 'Here are the risks we identified together. Here's how we're addressing them.' That transparency actually deepened the partnership. It turned a potentially adversarial exercise into a collaborative risk-management conversation. Luna: So red teaming, when done right, becomes a relationship-building tool. Lucas: It can be. It depends on how you frame it. If you frame it as 'we're trying to beat you,' you'll get resistance. If you frame it as 'we're trying to make sure we both succeed,' you get buy-in. Sarah chose the latter, and it paid off. Luna: Great case study. I'll definitely be thinking about this next time I review a supplier's capacity claims. Lucas: Same here. And if you try it, we'd love to hear how it goes. That's it for this episode of The Buyer's Side.
