Using Earliest Available Time

Earliest Available Time is a Task Constraint that schedules a task to begin at the earliest available time after considering any predecessor relationships. 

To update the Task Constraint to Earliest Available Time:

  1. Navigate to a task whose Task Constraint you want to update.
  2. Click Edit Task.
  3. In the Overview section, expand the Task Constraint drop-down menu.
  4. Select Earliest Available Time.
  5. Click Save Changes.

Understanding the Difference between Earliest Available Time and As Soon As Possible

[! This section is duplicated in "Earliest Available Time"]The Earliest Available Time constraint differs from the As Soon As Possible constraint when all of the following criteria exist:

  • The project is scheduled From Completion
  • Tasks in the project have a predecessor relationship
  • The predecessor task has a flexible task constraint

In this situation:

  • Earliest Available Time: Using the Earliest Available Time constraint on the successor task gives priority to the predecessor's flexible constraint.
    For example, suppose that Task A is a predecessor to Task B. Task B has the Earliest Available Time constraint and Task A has the As Late As Possible constraint. In this situation, the task is scheduled as close to the completion of the project as possible.
  • As Soon As Possible: In this scenario, using the As Soon As Possible constraint on the successor task gives the priority to the successor task.
    For example, suppose that Task A is a predecessor to Task B. Task B has the As Soon As Possible constraint and Task A has the As Late As Possible constraint. In this situation, the task is scheduled as close to the start of the project as possible.
