Dependency — A dependency is a situation where one task or activity relies on another to be completed first.

In plain English

A dependency means your work depends on someone else’s work.

You can’t finish until they do.

What they actually mean

Dependencies are where plans go to die.

They look harmless on a roadmap —
until one slips and takes three other tasks with it.

Most delays aren’t caused by bad execution.
They’re caused by underestimated dependencies.

Example

Does it actually matter?

✅ Yes — structurally.
Dependencies determine how fragile a plan really is.

✅ Fewer dependencies mean more control.
⚠️ Hidden dependencies mean surprise delays.
