Add an activity dependency

Add a dependency to link two activities in the Masterplan. A dependency makes one activity the predecessor or successor of another.

Add a dependency from the dialog

1. Open the activity's Dependency list in one of two ways:
   • Double-click the activity bar, then click the Dependency list tab.
   • Hover over a leaf activity in the Gantt chart. Boxes appear at the start and end of its bar. Click a box.
2. Click + Add New Dependency. The Create Dependency dialog opens.
3. Choose the Add Predecessors or Add Successors tab.
4. In Select Predecessor Activity (or Select Successor Activity), search for the activity by its name or WBS number, and select it.
5. Choose the Type: FS, SS, FF or SF. FF and SS are available only with milestones.
6. Enter the Lag in days.
7. Click Save.

Repeat these steps to add more dependencies. In the Dependency list, the Predecessors and Successors tabs show the dependencies you added.

Add a dependency by dragging

1. Hover over a leaf activity to show the boxes at the start and end of its bar.
2. Drag from one box to the start or end box of another activity. The Create Dependency dialog opens with the type already set. For example, from a finish box to a start box gives FS.
3. Click Save.

The video shows how.

Dependency types and lag

There are four types of relationship between activities:

• Finish-Start (FS)
• Start-Start (SS)
• Finish-Finish (FF)
• Start-Finish (SF)

Lag is the number of days added between a predecessor and its successor. With a Finish-Start lag of 2, the successor starts 2 days after the predecessor ends. Lean PlanDo does not support negative lag: you cannot type a negative value.

Adding a task dependency works the same way. See Add a task dependency.
