Who can do this

Admins and Project Managers can add and edit dependencies.

What a dependency does

A dependency links one task (the predecessor) to another (the successor) so that when the predecessor's dates change, the successor's dates automatically adjust to match.

Steps

  1. 1Open the Schedule tab for the project.
  2. 2Select the task that should depend on another.
  3. 3Choose the predecessor task it depends on.
  4. 4Pick the relationship type — most commonly Finish-to-Start (FS), meaning the successor starts after the predecessor finishes.
  5. 5Add lag days if there should be a gap between the two (for example, drywall mud needing a day to dry before paint starts).
  6. 6Save the dependency.

Other relationship types

Besides Finish-to-Start, Doxlair also supports Finish-to-Finish, Start-to-Start, and Start-to-Finish relationships for less common sequencing needs.
