Two Task Behaviors

Task links are constraints that control how linked tasks shift when a task's date is changed. QuickPlan supports two link types.

Please note the differences in how successors are moved.

  • Finish to Start: The traditional "Finish to Start" link ensures the predecessor's finish date is not later than the successor's start date.
    • When moving a predecessor, if its end date becomes later than the successor's start date, the successor moves to maintain the constraint.
    • Moving a successor does not affect the predecessor. Task links are typically used for rescheduling during execution; completed tasks (predecessors) should remain unchanged.
    • One task can link to multiple predecessors and successors.
  • Simple Link: Tasks are tightly linked; moving one task in a chain moves all other linked tasks simultaneously.
    • Sucessors move simultaneously with the predecessor.
    • Moving a successor does not affect the predecessor. Task links are typically used for rescheduling during execution; completed tasks (predecessors) should remain unchanged.
    • One task can link to multiple predecessors and successors.
    • We developed this feature based on user feedback. This link type feels more natural than traditional ones, though it is not standard in other planning apps.

Configure Project Task Link Behaviour

  • Tap to change the option.

Best Practice

Mathematical constraints are precise, but are they practical for large numbers of links? Read our article on how to organize tasks effectively.
