XKCD "Dependency"

Use when a sprawling system or large group quietly depends on one overlooked person doing the load-bearing work.

What it expresses: Many people assume the operation sustains itself, while one under-supported contributor actually keeps every dependent part functioning.
Example: Thirty people attend the launch, but one coordinator handles every booking, reminder, access request, and last-minute rescue alone.
When not to use it: Avoid when responsibility is genuinely distributed across several supported owners rather than resting on one hidden dependency.
