Here’s how the four dependency types work:
Finish-to-start: A finish-to-start dependency is the most common type
of dependency link. In this relationship, the predecessor task must be
completed before the successor task can start. When you create a
dependency, the default setting is finish-to-start.
An example of a finish-to-start dependency is when you must complete
the Print Invitations task before you can begin the Send Out Invitations
task. Figure 6-2 shows two tasks with the finish-to-start relationship
indicated by a successor taskbar that starts where the predecessor taskbar
Start-to-finish: In a start-to-finish dependency, the successor task can
finish only after the predecessor task has started. If the predecessor is
delayed, the successor task can’t finish.
Suppose that you’re planning the building of a new cruise ship. You
might start selling tickets for the ship’s maiden voyage while the ship is
being built, and you don’t want to stop selling tickets until the ship is
ready to leave. So, the predecessor task is Ship Ready for First Voyage (a
milestone), and the successor is Sell Tickets for Maiden Voyage. If the
ship isn’t ready, you can keep selling tickets. When the ship is ready to
go, the ticket windows close, and that task can finish. Bon voyage!
