How to enter Tasks Duration

When determining the duration of tasks, you will consider only the tasks at the lowest level of the WBS: the Elementary tasks or Children tasks.


If your Schedule Mode is "Critical Chain", do not forget to select the Planning Mode. The Switch to Tracking Mode (alarm22_md.png) button must be displayed in the Main toolbar.

  1. Log in to the HTML5 client.

  2. Select the Work workspace, Gantt tab.

  3. Select a project in the Project Data Selector.

  4. Select the Scheduler (viewmode_activegantt22_md.png) mode.

In the Gantt spreadsheet

  • In the Gantt spreadsheet, enter a value in the Duration field of each elementary task.


The duration of Parent tasks will be computed automatically.

In the Gantt chart

  1. Place the mouse pointer at the end of the task to be extended.

  2. When the Extend task (GanttExtendTask.png) icon appears, hold down the left mouse button and drag the task to the date to which the task needs to be extended.


Extending a task is the same as if the user were defining a new task Duration or a new Finish date.
