Start-to-Start (SS)


In project scheduling, setting a dependency rule that the ‘start date’ of a particular task is dependent on the ‘start date’ of its specified predecessor task.

Project Manager Usage Context

Setting Start-to-Start dependencies is done within a project scheduling application such as MS Project by either the Project Manager of a Project Scheduler.

Start-to-Start is one of the less common task dependencies.

Setting task dependencies is an integral part of working out the planned duration of your project as well as critical to both the sequence order and timing of all project tasks.

Comments / Tips

To avoid any confusion with your project stakeholders, avoid using the term “Start-to-Start” when communicating this sort of dependency.

Rather, lay it out in layman's terms.

E.g. “We need to ensure that Team B starts their system testing as soon as Team A starts.”

There are 4 types of task dependencies - also see :
