5 Mistakes That Ruin a Supply Chain Stress Test

When it comes to resilience, practice beats theory. A supply chain stress test—or as we call it, a War Game—lets your team rehearse what happens when things go sideways. It’s the difference between reacting in chaos and responding with clarity.

But not every stress test builds real muscle. Too often, teams walk away with notes and no next steps. Here are five common mistakes that turn a promising exercise into another lost afternoon—and how to fix them.

1. Too many scenarios, too little depth

It’s tempting to throw in every possible disaster: port strikes, system outages, truck thefts, supplier shutdowns. But when everything’s a crisis, nothing gets solved.

Do this instead: Pick one or two realistic, high-impact disruptions. Then go deep—trace the ripple effects through planning, procurement, fulfillment, and finance. Clarity comes from depth, not breadth.

2. Leaving functions out of the room

If your stress test only includes ops or logistics, you’ll miss the full picture. Finance, marketing, and customer service all feel the shockwaves of disruption.

Do this instead: Bring a cross-functional group to the table. War games work best when the people who feel the pain are part of the solution.

3. Overly wild hypotheticals

A meteor hitting your 3PL isn’t strategy—it’s entertainment. The point isn’t to imagine every apocalypse; it’s to prepare for the disruptions most likely to happen to you.

Do this instead: Use real data to pick plausible risks. A hurricane near your port, a packaging recall, or a carrier strike are enough to surface where your systems bend—or break.

4. No documentation or ownership

If no one takes notes—or worse, no one owns the action items—you’ve wasted your time.

Do this instead: Assign a scribe and create a shared document that captures decisions, gaps, and next steps. Then assign owners with deadlines. A stress test without follow-up is just theater.

5. Treating it as a one-time event

Supply chains evolve. So do their risks. Running one stress test and calling it “done” is like exercising once and expecting endurance.

Do this instead: Build a cadence. Run mini-tests quarterly or after major system or supplier changes. The goal is a team that knows what to do before the crisis hits.

Case in Point: Quiet Platforms

When Quiet Platforms scaled its logistics network, it didn’t just expand capacity—it closed systemic gaps.

Through better orchestration, shared infrastructure, and unified visibility, Quiet transformed a fragmented fulfillment ecosystem into one resilient enough to handle volume spikes and regional disruption.

The result: lower delivery costs, faster speed, and higher reliability across brands.

It’s a reminder that resilience isn’t just about reacting—it’s about redesigning the system to absorb shocks before they reach the customer.

The takeaway

Resilience isn’t built in the moment—it’s built in rehearsal.

A supply chain stress test is your chance to surface weak points, define ownership, and turn chaos into clarity.
