What is the Swiss Cheese Model and how does it work?

The Swiss Cheese Model, developed by safety scientist James Reason, pictures an organization's defenses against failure as stacked slices of Swiss cheese. Each slice is a barrier—a review, a checklist, an owner—and each has holes, representing its inherent weaknesses. A failure only gets through when a hole in every slice momentarily lines up, creating a clear path. For teams, it explains why no single safeguard is enough and why you need complementary, overlapping layers.

Who created the Swiss Cheese Model?

Psychologist James Reason of the University of Manchester developed the model, introducing it in his 1990 book *Human Error* and popularizing it in his 2000 BMJ paper "Human error: models and management." It became foundational in aviation, healthcare, and other high-reliability fields, and is now widely borrowed for cybersecurity ("defense in depth") and team operations.

What is the difference between latent and active failures?

Active failures are the immediate unsafe acts at the point of work—a missed reply, a wrong entry, a forgotten follow-up. Latent failures are the dormant conditions that let those acts cause harm: an unclear process, an unowned task, a tool nobody checks. Active failures trigger an incident; latent failures are why it slips through. You fix latent failures by repairing the system, not by telling people to try harder.

What is the difference between the Swiss cheese model and the Swiss cheese method?

They're unrelated despite the name. The Swiss cheese *model* is Reason's theory of how failures pass through layered defenses. The Swiss cheese *method* is a personal-productivity tactic for beating procrastination by poking small "holes" in a big task—doing tiny chunks whenever you can. This article is about the model.

Why does work fall through the cracks in remote teams?

Because remote work replaces ambient, in-person safeguards with explicit, tool-mediated handoffs, and each handoff has a hole at the same point: turning a live decision into owned, findable work. Ad hoc and cross-time-zone meetings leave no durable record, context scatters across apps, and owners go unnamed—so the holes in your meeting, notes, handoff, and follow-up align, and the work drops through. Capturing decisions at the source closes the biggest gap.

The Swiss Cheese Model for Remote Teams

Microsoft's 2025 Work Trend Index found that employees are now interrupted every two minutes during core work hours—275 times a day by meetings, emails, and chats. In a distributed team, every one of those interruptions is a moment where a decision can go unrecorded or an owner can go unnamed. When work later falls through, the instinct is to blame a person: someone forgot, someone dropped the ball. That's almost never the real cause.

The real cause is structural, and a safety scientist named James Reason mapped it decades ago. The Swiss Cheese Model for remote teams is the most useful mental model you can borrow for understanding why things slip. Your team's safeguards are like stacked slices of Swiss cheese—each one full of holes. Trouble gets through only when those holes happen to line up.

This piece explains what the model actually says, why remote and hybrid work punches more holes than the office ever did, where each of your defensive "slices" leaks, and how to stack them so the gaps stop aligning.

What the Swiss Cheese Model Actually Says

The Swiss cheese model was developed by James Reason at the University of Manchester and laid out in his 2000 BMJ paper "Human error: models and management". It's the backbone of safety thinking in aviation, healthcare, and engineering—anywhere a single mistake can be catastrophic.

The idea is simple. Picture your defenses against failure as slices of Swiss cheese stacked side by side. Each slice is a barrier: a checklist, a review, a second pair of eyes. None of them is solid—every slice has holes, the weaknesses inherent to that defense. On any given day the holes shift around. Disaster strikes only in the rare moment when a hole in every slice lines up at once, creating what Reason called a "trajectory of accident opportunity." The hazard passes straight through.

Reason also drew a line between two kinds of holes. Active failures are the obvious unsafe acts at the sharp end—the missed reply, the wrong number typed in. Latent failures are the quiet conditions that sit dormant in the system for weeks: an unclear process, a tool nobody checks, a norm everyone has stopped questioning. Active failures trigger the incident; latent failures are what let it through. Understanding latent and active failures is the difference between blaming the person who typed the wrong number and fixing the system that made the error invisible.

That distinction matters for one reason: you cannot fix a latent hole by telling people to be more careful. You fix it by adding or repairing a layer.

Why Remote Teams Have More Holes in the Model

The model was built for cockpits and operating rooms, but it describes a distributed team eerily well—because remote work quietly drills new holes into every slice. Preventing mistakes in distributed teams starts with seeing where those holes come from.

In an office, a lot of defense is ambient and free. You overhear the decision. You catch someone at their desk to confirm an owner. You see the whiteboard the next morning. Remote work strips all of that out and replaces it with explicit, tool-mediated handoffs—and each handoff is a new seam where work can slip.

The data shows the seams widening. Microsoft found that 57% of meetings are now ad hoc calls without a calendar invite, and nearly a third of meetings span multiple time zones, up 35% since 2021. An ad hoc, cross-time-zone call produces decisions with no agenda, no durable record, and half the stakeholders absent. Meanwhile, context is scattered across more tools than anyone can track: Asana's Anatomy of Work report found that 60% of knowledge-worker time goes to "work about work"—duplicated effort, status-chasing, and juggling apps—and that a quarter of people using sixteen or more apps miss messages and actions because of the constant context-switching.

The result is a team that *feels* well-defended—you have meetings, you have Slack, you have a project tracker, you have an AI notetaker—but whose slices all have holes in roughly the same place: the moment a decision is made and needs to become durable, owned work. No surprise that Atlassian's State of Teams 2025 found teams waste 25% of their time just searching for answers they already produced once. That's the hazard passing through.

The Slices in Your Defense—and Where Each One Leaks

Most write-ups of the model stay abstract: "add redundant barriers." That's useless until you name the actual slices in a remote team's stack. Here are the five that matter, and the hole in each. These are your real-world swiss cheese model examples.

The Live Meeting

The meeting is your first slice. Everyone's together; alignment happens in real time. The hole is that nothing said in the room is captured unless someone deliberately writes it down—and in a cross-time-zone team, the people who most needed to hear it often weren't there. A decision made out loud at 4 p.m. in New York is invisible to the teammate logging on in Singapore. The slice did its job for the people present and left a hole for everyone else.

The AI Notes and Recording

This is the newest slice, and teams are leaning on it hard: a 2026 industry report found 75% of professionals now use an AI notetaker, and that the average professional otherwise burns 146 hours a year reconstructing meeting context. Real value—but the slice has a specific hole. Verbatim transcription is reliable; the *summary* is where it leaks. An AI summary will confidently record that you decided to launch in one market when you were debating another, or flatten a tense "let's not do this yet" into a clean action item. The recording captured every word and still missed the decision.

The Action-Item Owner

A decision without a single named owner is a decision that won't happen. This slice is supposed to assign accountability, and its hole is the most expensive one in remote work: the diffuse "we should do that" that no individual ever picks up. As AI agents start *doing* work, the hole widens—"the agent handled it" becomes the new "I thought someone else had it." This is exactly how action items get lost in remote meetings: not because the work was hard, but because ownership was never pinned to a person.

The Async Handoff

Between meetings, work moves through Slack threads, docs, and tickets. This slice covers the gaps between live calls—and it's riddled with holes, because a decision buried in message 47 of a thread is functionally lost. Without strong async communication habits, the handoff degrades into "I'm pretty sure we agreed to…," and the actual rationale—the provenance of the decision—evaporates. Two weeks later someone reopens the settled question because no slice preserved the answer.

The Follow-Up

The last slice is the standup or review where dropped work is supposed to surface. Its hole is timing: by the time a forgotten item shows up, the context is gone and the cost has compounded. Worse, when nobody can find the original decision, two people quietly redo it—which is how distributed teams end up with duplicated work nobody intended.

Notice the pattern. Every slice is genuinely useful, and every slice has a hole at the same point in the workflow: capturing a live decision and turning it into owned, findable work. When all five holes sit on top of each other, the decision falls straight through the stack.

How to Strengthen the Swiss Cheese Model for Remote Teams

You don't fix this by demanding more diligence, and you don't fix it by buying more tools. You fix it by stacking layered defenses for remote teams so intelligently that the holes no longer align. Four principles do most of the work.

Add complementary layers, not redundant ones. Three chat apps are not three slices—they're one slice with the same hole, copied. A real second layer covers a *different* failure mode. If your meeting captures discussion, your second layer should capture decisions and owners, not just re-record the conversation. Stacking tools that all leak in the same spot, the SaaS sprawl most teams suffer from, is the illusion of defense.

Capture at the source, not after the fact. The biggest latent hole is the gap between when a decision is made and when someone remembers to write it down. Close it by capturing the decision *in the room, as it happens*, tied to the moment and the people who made it. A decision recorded at the source can't depend on anyone's memory later.

Keep one durable artifact per decision. A decision that lives in five places lives in none. Each one needs a single home—what was decided, why, and who owns the next step—that anyone in any time zone can find without asking. That one artifact is the slice that has no hole.

Make the work visible. Holes hide in the dark. When the canvas, the decision, and the owner are visible to the whole team, a missing owner or an unrecorded outcome becomes obvious in the moment instead of two weeks later.

This is the thinking behind Coommit. Putting video, an interactive canvas, and contextual AI on one surface adds a slice precisely where the others leak: the AI watches both the conversation and the canvas, so the decision and its owner are captured as they're made, in one durable place the whole team can see. It doesn't replace your other slices—it's positioned to cover their shared hole.

The Bottom Line

Work doesn't slip through your team because people are careless. It slips because every safeguard has a hole, and remote work keeps nudging those holes into alignment. The Swiss Cheese Model for remote teams turns a vague frustration—"things keep falling through"—into a precise diagnosis you can act on: find the slice that's missing, and stack it where the others leak.

The stakes are rising, not falling. As AI adds a powerful new slice to every team's stack, it adds new holes too—the confident-but-wrong summary, the action nobody owns because "the agent had it." Intelligence scales automatically; accountability does not. The teams that win the next few years won't be the ones with the most tools. They'll be the ones whose holes never line up.
