    Project task relationships and dependencies

    The Project Management application enables you a create parent-child relationships between tasks and dependencies, such as finish-to-start and finish-to-finish, between tasks.

    This table explains the types of task relationships and dependencies that you can create.
    Table 1. Project relationships and dependencies
    Concept Description
    Finish-to-start dependency A dependency that indicates that a task must not be started until its predecessor finishes.
    Start-to-start dependency A dependency that indicates that a successor task must not be started until the predecessor task has started.
    Start-to-finish dependency A dependency that indicates that a successor must not be finished until the predecessor task starts.
    Finish-to-finish dependency A dependency that indicates that a task must not be finished until another task finishes.
    Lag time A manually specified time break between predecessor and successor tasks.
    Parent task A project task with smaller tasks, referred to as child tasks, underneath it. Child tasks break down the work of a parent task into more manageable subsets. Certain fields for child tasks, such as planned end date, roll up and affect the same field in the parent task.
    Child task A project task that is a subset of a larger task. Child task start dates cannot occur before the start date of the parent task.
    Rollup task Another term for a parent task in the context of aggregating child task items, such as effort or resources, into a larger parent task calculation. All fields on rollup task forms are read-only.
    Roll down State changes roll down from the project to project tasks, and from parent tasks to child tasks.
    Note: Only one relationship can exist between two tasks.

    The Project Management application provides several properties that control how tasks are calculated and behave. See Project property for more information.

    • Project task dependencies

      A task dependency is created when one task is prevented from starting or finishing based on the state of another task.

    • Parent-child task relationships

      If a task is relatively large and requires several users with different skills to manage, break the task into subtasks and create parent-child relationships. A child task is a relatively smaller, manageable size of work.

    • Parent-child rollup task calculations

      Date changes, stage changes, and value calculations roll up from child tasks to parent tasks.
