Add a task dependency

Add a dependency between tasks under an activity when one task must follow another. You do this in the Lookahead (the 6-week or 8-week plan where activities are broken down into smaller tasks).

A task dependency is the relation between two tasks. Adding a dependency makes a task the successor of a predecessor task. The successor respects the predecessor's end date.

You can also add a cross dependency between tasks under different activities, to show how they relate. The steps are the same.

Add a dependency

1. Double-click the task bar in the Gantt chart.
2. Open the Dependency list tab and click Add New Dependency.
3. Choose Add Predecessors or Add Successors.
4. In Select Predecessor Activity (or Select Successor Activity), select the activity.
5. In Select Predecessor Task (or Select Successor Task), select the task.
6. Choose the Type: FS, SS, FF or SF.
7. Enter the Lag in days.
8. Click Save.

Repeat the steps to add more dependencies.

You can also add a dependency by drag and drop: drag from the box of one task to the box of another. This opens Create Dependency.

Good to know

Dependency types:

• FS: Finish-Start
• SS: Start-Start
• FF: Finish-Finish
• SF: Start-Finish

Lag is the number of days added between a predecessor and its successor.

You cannot add a predecessor to a committed task. The app shows "A predecessor dependency cannot be added for a committed task".

The Dependency list tab does not show in the Do tab.

Activity dependencies are added the same way. See Add an activity dependency.
