- Using the Earliest Available Time Constraint
- Understanding the Difference between Earliest Available Time and As Soon As Possible
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:
- Navigate to a task whose Task Constraint you want to update.
- Click Edit Task.
- In the Overview section, expand the Task Constraint drop-down menu.
- Select Earliest Available Time.
- Click Save Changes.
[! 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.
