# Predecessor dependencies in the planning console

In the WBS section of the planning console, you can create dependencies between tasks by specifying a series of values.

The **Predecessor** column on the planning console can specify dependencies between tasks. The values that you put in this column must be in the following format:

`{WBS_number}{dependency_type}+{lag_time}`

Where

-   `WBS_number` is the number of the predecessor task in the relationship.
-   `dependency_type` is one of the [types of dependencies](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-business-management/project-management/c_ParentChildRollupTaskCalcs.md) that the application supports.
-   `lag_time` is the amount of time, in days, to delay the start of the dependent task. This value can be positive or negative integers.

The values are entered without the curly braces \{\}. See the examples in the table.

**Note:** You can also edit tasks from the Gantt chart by clicking the relationship line. See [Gantt chart options](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-business-management/project-management/r_EditTasks.md) and [Modify a project task dependency](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-business-management/project-management/t_ModifyProjectTaskDependencies.md) for details.

|Dependency type|Example|Additional information|
