Create Gantt chart relations

After creating the phases, milestones and tasks for your Gantt chart you can continue by creating follows and precedes relationships between them. To do this, activate the Gantt chart and right click on an element (e.g. a phase). Select either Add predecessor or Add follower to add a preceding or following work package.

Follows precedes relationship

This highlights the selected work package. You can now click on the work package to which you would like to create a relationship. Note that this may reschedule the selected work package to correctly reflect the relationship.

Create relationship

When you reschedule the preceding task, phase or milestone, the following work package will be updated accordingly.

To remove a relationship again, open the work package details view, select the Relations tab and click on the remove icon. For details, take a closer look at work package relations.

Frequently asked questions (FAQ)

Why are the relations lines in the Gantt chart not shown properly?

Make sure that the browser zoom level is set to 100%. If you use a different browser zoom level (e.g. 90%), the lines may not be displayed correctly.

Adding a follow / precedes relationship adds a delay of at least one day. Can I schedule multiple work packages on the same day and still have a follows-precedes relationship?

When you create a follows-precedes relationship between work package, there will always be a delay of at least one day (i.e. no two tasks which are in a follows-precedes relationship can have overlapping dates). If you have smaller tasks which take less than a day to complete, you can create a common work package parent (with the duration of at least one day) and assign all the smaller tasks as children to this parent work package. The child tasks can then be scheduled on the same day. Instead of creating a follows-precedes relationship between the children, you can create a relationship between the work packages preceding and following the parent work package.
