You know the feeling. Your team's retros are positive. Velocity is stable. People genuinely like working together. Psych safety is high — folks admit mistakes, ask dumb questions, challenge each other without it getting weird. By every internal measure, you're a healthy, high-performing team.

And yet.

Every dependency is a nightmare. Every cross-team interaction feels like pulling teeth. You're waiting three weeks for a PR review from another squad. Their API keeps breaking yours. Planning sessions with them feel like hostage negotiations. And the conclusion your team reaches — naturally, inevitably — is: "We're fine. It's them."

I've been in this room. Multiple times. On both sides of it. And I've come to believe that this specific pattern — a team that feels healthy internally but generates friction at every boundary — is one of the most dangerous failure modes in engineering orgs. Not because it's dramatic, but because it's invisible. The team genuinely is healthy by local measures. That's what makes it so hard to diagnose.

I've started calling this the insular health fallacy — the belief that internal team health equals systemic health. The team isn't broken. The interface is broken. But from inside, it looks like everyone else is the problem.

Social psychology has a name for the underlying mechanism: in-group bias. The minimal group experiments in the 1970s showed that people will favour their own group — even when the groups are assigned randomly. Give people a label, any label, and they'll start preferring "us" over "them." Now imagine what happens when "us" is a team that's genuinely built trust, shared context, and psychological safety over months or years. The in-group cohesion becomes a fortress. And fortresses, by design, keep people out.

In software engineering, cognitive load refers to the total amount of mental effort being used in a developer's working memory to complete a task. Think of it like the RAM in a computer: if you try to run too many heavy applications at once, the system slows down, glitches, or crashes.

When a developer's cognitive load exceeds their mental capacity, productivity drops, the quality of code suffers, and the risk of burnout increases.

Somewhere in your organisation right now, an engineer wants to use a tool. It's open source. It's battle-tested. Half the Fortune 500 runs it in production. But first, they need to fill out a vendor assessment form, get InfoSec sign-off, wait for procurement to confirm there's a contract in place, and then — maybe, in four to six months — they'll get a "yes" or a "no" from a committee that's optimised for risk avoidance, not risk management.

This isn't an argument against governance. Governance matters — especially in regulated industries. This is an argument that the way most enterprises do governance today is broken: optimised for the appearance of control rather than the reality of it. The question isn't whether to govern. It's whether your governance framework is actually reducing risk — or just reducing speed.

Meanwhile, the startup down the road shipped the feature last Tuesday.

But hey, at least you've got a contract. You can sue them if things go wrong. Right?

A new project kicks off — migrating a critical system to a platform nobody on the team has used before. Well, almost nobody. There's one person who's built on it. Shipped production workloads. Knows the failure modes.

They don't get the lead. The person with the most years of experience does. The senior. The one with the title.

Everyone defers. The titled lead chairs the meetings, makes the architecture calls, approves the designs. The person who actually knows the platform sits three rows back on the call, unmuted only when asked a direct question.

Six weeks later, the project is behind. Decisions are being revisited. The team is frustrated but can't quite name why.

You've seen this movie. Maybe you've been in it. Maybe you've been on both sides.

I'm a new parent. I have no idea how to be a good father. I've read zero parenting books. I have no framework, no methodology, no "5 pillars of effective fatherhood."

But I know what a bad father looks like. I know what breaks trust. I know what makes a child stop talking to you. I know what happens when you're physically present but emotionally absent.

I don't have a playbook for getting it right. I have a very clear list of things to never do.

Turns out, that's enough. And it applies to more than parenting.

Look, you worked hard. You stayed late. You shipped that thing nobody else could ship. You earned every single promotion, every bit of recognition, every seat at the table. It was all you. 100%. No asterisks. No footnotes. Definitely no luck involved.

Right?

You send a Slack message to another team. It's a reasonable request — a small API change, maybe a code review, maybe just a question about how their service handles edge cases. You write it clearly. You tag the right person. You even add a polite emoji. And then... nothing. No reply. No acknowledgment. Just the quiet hum of a message marked as read and promptly ignored.

You're not being ghosted because they're bad people. You're being ghosted because the game they're playing rewards ignoring you.

This isn't a people problem. It's a math problem.

You've seen it. Every team is shipping. Every sprint has velocity. Dashboards are green. And yet somehow, the organisation feels slower than it should. Everyone's busy, but nothing moves faster.

Here's a clue from an unexpected place.

Picture a motorway at rush hour. Every driver is making the smartest choice for themselves — fastest lane, shortest route, optimal speed. Nobody's doing anything wrong. And yet the whole system grinds to a halt. More cars, more rational decisions, more gridlock.

This isn't a failure of individual intelligence. It's a failure of coordination. Game theorists have a name for it — the Price of Anarchy — and it might be the most useful mental model for understanding what management actually is, when it matters, and when it doesn't.

Look, I get it. Someone at a conference said "InnerSource" and now Slack is buzzing — or is it Teams? Honestly, who can keep track anymore. People are sharing links to the InnerSource Commons, talking about "breaking down silos" and "cross-team collaboration" like they've discovered fire. Let me save you the trouble — here's why you should absolutely, categorically, never do InnerSource.
