You look at the org chart and the headcount report says the team is basically intact. Then the sprint slips. A rollout stalls because the one person who understood the old deployment flow is gone. Finance asks why you're still paying for seats nobody uses. Support tickets bounce between people because ownership got fuzzy after two “small” exits.
That's usually the moment attrition stops being an HR term and starts looking like an operations problem.
The plain attrition rate meaning is simple. It's the rate at which people leave a team or company and aren't replaced. That last part matters. If someone exits and the role stays empty, your capacity dropped, even if payroll hasn't fully caught up with reality yet. In practice, that shows up as delayed work, tool sprawl, underused licences, longer onboarding pressure on the remaining team, and more meetings because fewer people still hold the context.
For IT leaders in the Netherlands, this lands fast. Hybrid teams can look stable on paper while actual delivery gets slower week by week. The damage isn't dramatic. It's operational drag. A few missing people, a few idle laptops, a few SaaS seats nobody reclaimed, a few senior staff spending too much time covering basics instead of moving projects forward.
Attrition is the quiet loss of capacity you feel before it appears clearly in the budget.
If you manage endpoints, software spend, or engineering throughput, attrition belongs on your dashboard for the same reason uptime and licence use do. It tells you whether the team that should be doing the work still exists in a usable form.
