A Fixed dependency enforces a set date relationship between two items. When the first item’s dates change, the second item automatically shifts to preserve the same gap between them—keeping their timing locked relative to each other on the timeline.
Begin by expanding the item and go to the
section of the card.
⚠ Warning: Fixed Dependencies Can Impact Downstream Dates
Fixed dependencies maintain a rigid time gap between connected items. If one item moves, all linked items will shift accordingly to preserve the same interval.
This means that changes to a single task can unintentionally push or pull critical downstream dates.
If you're concerned about key milestones moving, you can lock the start or target dates of an item to prevent unintended changes.
You can add a Fixed dependency as either Blocked By or Blocking, depending on how you want the relationship to flow.
In this article, we’ll add a Fixed dependency and set it to Blocking. To get started, click the Is blocking selection bar.
If you’re adding a Blocked By dependency, select the Is blocked by selection bar instead.
Under each selection bar you will see a list of available items that you can link as dependencies.
