Two Task Behaviors

Task links are the constraints between tasks to control how to change the date of other linked tasks after changed a task's date. QuickPlan supports two task link types.

Please pay attention to the differences in the condition to move the successors.

  • Finish to Start. The traditional "Finish to Start" task link defines the constraint that the predecessor task's finish date cannot be later than the successor's start date.
    • When moving a predecessor, suppose the predecessor's end date will be later than the successor's start date. The successor should also move to keep the constraint valid.
    • Moving a successor will not impact the predecessor. As typically, we use the task links for re-scheduling when executing the project. When re-scheduling, the passed tasks should be completed, which can not be changed again.
    • One task can link with multiple predecessors and multiple successors.
  • Simple Link - Linked Tasks are really linked, moving one task in a linked list, other tasks in the linked list will be moved simultaneously.
    • All the successors move simultaneously with the predecessor.
    • Moving a successor will not impact the predecessor. As typically, we use the task links for re-scheduling when executing the project. When re-scheduling, the passed tasks should be completed, which can not be changed again.
    • One task can link with multiple predecessors and multiple successors.
    • We developed this feature for QuickPlan based on the feedback from the users. This link type is more natural than the traditional link types. However, it is not a standard one supported by other planning apps.

Configure Project Task Link Behaviour

  • Tap the project name on the toolbar in an opened project window to edit project properties, including link behavior.
  • Tap to chagne the option

Best Practice

Using constraints from a mathematical perspective is a perfect approach, yet is it an excellent way to use task links in large quantities? We have an article related to the way to organize the tasks well.
