Projects rarely operate in isolation. Without task-level interdependency tracking, dependencies can be missed, delays may be identified too late, and schedules can become unreliable.
How PPM360 supports interproject dependencies
- Makes upstream and downstream relationships visible.
- Helps prevent work from starting before prerequisites are complete.
- Supports proactive replanning when upstream delays occur.
Creating an interproject dependency is simple.
- Open the upstream project.
- Select New Interproject Dependency.

- Select the task that must be completed first. This is the upstream task.
- Then select the downstream project and task.

Interproject dependencies are visible in both the upstream and downstream project task schedules.
- Changes to the upstream task start date, finish date, or effort are visible within the downstream task schedule.
- Changes to the downstream task start date, finish date, or effort are visible within the upstream task schedule.
By default, these dependencies are soft, meaning that changes to an upstream task do not automatically update the downstream project schedule. However, project managers can use native Planner functionality to create task dependencies within their own schedule. Changes to linked tasks outside the parent project are visible, but they are not committed automatically to either schedule.
