Delivery management - Concept
Dependency
Something that must happen or be available before another piece of work can finish
What's it for?
Shows which work must happen first so plans and dates are realistic.
For example…
The mobile app cannot launch until the identity team finishes single sign-on—tracked as an external dependency.
User training depends on the final workflow being agreed, so a delay in process design pushes the training start date
Think of it like…
Needing the electrician before the plasterer: one trade blocks the next if the order is wrong
