Start-to-start (SS)

Start-to-Start Relationships 

SS precedence relationships are used in situations where one or more key activities must be started at the same time so that a project can remain on schedule.  An SS dependency requires that the predecessor activity be scheduled to start before or simultaneously with the successor activity.  In the following example, activity 1.2 cannot start until activity 1.1 has started.
  
These are examples of SS relationships:
