To make one Asana task wait for another, open the task that must wait, select Add dependencies in its details pane, and choose the task that must happen first. The waiting task will be marked Blocked by the prerequisite task. You can also create and inspect dependencies in a project list, Timeline, or Gantt view.

Set a dependency from task details

  1. Open the task that cannot start or finish until another task is done.

  2. In the task details pane, select Add dependencies or find the Dependencies field.

  3. Type the name of the task that must happen first. Where supported, you can paste that task’s URL instead.

    Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  4. Select the matching task from the suggestions. The task you opened is now Blocked by the selected task.

  5. Check the direction before saving or moving on: Blocked by means this task is waiting; Blocking means this task is holding up another one.

You can add more than one prerequisite to a task, and a prerequisite can block more than one task. To remove a link, hover over its dependency indicator and select the X. For Asana’s instructions, see Task dependencies.

Choose the best place to create or view the link

Where you work How to use it Best suited for
Task details Open the waiting task and use Add dependencies or its Dependencies field. Creating a link when you know which task is waiting and which task is the prerequisite.
Project list Use the project’s field or column controls to add Blocked by and Blocking columns. Reviewing dependency direction across tasks in a list.
Timeline Hover over a task to reveal its connector, then drag the connector to the task that depends on it. Creating or checking links alongside a visual schedule.
Gantt Hover over a task block and drag its dependency handle to another task; use the dependency-type selector after linking. Working with a Gantt schedule or choosing a specific dependency type.

In Timeline, a grey connector indicates no date conflict; a red connector indicates a potential conflict, such as a dependent task starting before its prerequisite is complete. See Asana’s guides to managing tasks and dependencies with Timeline and Gantt view.

Understand dependency direction and types

Blocked by and Blocking describe the same link from opposite sides. If task B cannot proceed until task A is done, B is Blocked by A, while A is Blocking B. Thinking through the relationship this way helps prevent linking the right tasks in the wrong direction.

Asana documents four dependency types. Choose the one that matches how the work overlaps; the type selector is available in Gantt after you create the link.

Know when dependent dates will shift

Creating a dependency does not by itself guarantee that Asana will move dates. Auto-shifting is a separate project setting, and it depends on linked tasks having relevant due dates, the chosen shifting behavior, and the tasks not being completed. When you change dates outside Timeline or Gantt, Asana describes a preview modal showing the resulting dates for dependent tasks.

Asana documents three ways to handle schedule buffer:

  • Maintain buffer: preserve the gap between dependent tasks when dates shift.

  • Consume buffer: use the gap as schedule changes occur.

  • Ignore buffer: do not preserve or consume that gap when shifting dates. Asana’s auto-shifting documentation describes None as the default; it says only new projects with a Gantt tab are set to Consume buffer.

Timeline has a route to project dependency settings through the project’s options. Check the setting in your project before relying on automatic date changes. See Asana’s auto-shift dates documentation and Timeline guide.

Notifications and optional automation

Asana says the assignee of a dependent task is notified when its prerequisite is marked complete, or when the prerequisite’s due date is changed or removed. If the waiting task has multiple prerequisites, its assignee receives one notification after all of them are complete.

You can also create a project rule triggered when a task is no longer blocked. The rule can then take actions such as setting a due date, moving the task to a section, or adding collaborators. This is optional; it is not needed to create the dependency. See Asana’s guide to using dependencies to kick work off at the right time.

Availability

Asana’s cited help pages list dependencies and Timeline for Starter, Advanced, Enterprise, Enterprise+, and certain legacy tiers, including Premium, Business, and Legacy Enterprise. Plan names and entitlements can change, so check the current availability in your Asana account rather than treating those help-page lists as a current pricing comparison.
