What is task dependency and what is it used for?

Some tasks need to be completed in a particular order. When the approach to a certain task depends on the result of another, dependency helps associate them together and determine an order to work. Projects' end-to-end Gantt visualization provides a bird's eye view of your tasks, helping you track them easily. Using the Chronology Gantt chart and the Milestone Gantt chart, you can effortlessly establish dependencies between tasks.

Feature Availability:
  1. Dependency between tasks of the same project: Premium and Enterprise plans
  2. Dependency between tasks across projects: Enterprise  plan

Types of Dependency

Zoho Projects supports four types of dependency.

  1. Finish-To-Start (FS) : The successor or dependent task can’t begin until the predecessor or parent task is finished. For instance, in a journal publishing process, self-review of a journal can’t begin until the draft is completed by the writer.

  2. Start-To-Start (SS): The successor or dependent task can’t begin until after the predecessor or parent task has started. For instance, as the peer review of the journal starts, the manager review can also be initiated.

  3. Finish-To-Finish (FF) : A task (successor/predecessor) can't be completed until the other task is finished. 
    For instance, error correction can't be completed until the manager review is finished.

  4. Start-To-Finish (SF) : The successor or dependent task can be completed when the predecessor or parent task is about to begin.  For instance, publishing the journal can’t be completed unless the journal binding starts.
