Definitions for "Logical relationship"
A dependency between two project activities, or between a project activity and a milestone. The four possible types of logical relationships are: Finish-to-start. The initiation of work of the successor depends upon the completion of work of the predecessor. Finish-to-finish. The completion of work of the successor cannot finish until the completion of work of the predecessor. Start-to-start. The initiation of work of the successor depends upon the initiation of work of the predecessor. Start-to-finish. The completion of the successor is dependent upon the initiation of the predecessor.
The connection of two variables or project tasks based on a direct cause or dependency, rather than coincidence.

Finish-to-finish -- the "from" activity must finish before the "to" activity can finish. Start-to-start -- the "from" activity must start before the "to" activity can start. Start-to-finish -- the "from" activity must start before the "to" activity can finish. Finish-to-start is defined as the standard (or default) logical relationship.
