The Project management application supports two types of external dependencies - hard
and soft.
The type of external dependency can be set during adding a dependency between two projects tasks on the planning console.
Hard dependencies
In a hard dependency, any changes made in the predecessor project are automatically
propagated to the successor project. A notification for the changes made is triggered in the successor project. The
following image shows the process flow for a hard dependency type:Figure 1. External hard dependency
Soft dependencies
In a soft dependency, any changes made in the predecessor project trigger a notification
in the successor project. As the project manager of the successor project, you can choose to
accept or reject the changes in the notification. If you accept the notification changes,
the changes in the predecessor project are synced to the successor project and the project
is recalculated. If you reject the notification changes, the changes are not propagated to
the successor project. The following image shows the process flow for a soft dependency
type:Figure 2. External soft dependency
