Finish-to-start dependency. (Image courtesy of Wikipedia.)

A finish-to-start dependency between activities is one of the four possible logical relationships between activities in a schedule using the precedence diagramming method (PDM). With a finish-to-start relationship, the successor activity cannot begin until the predecessor activity is complete. This is the most common dependency relationship between activities. It is used for about 95% of the activity relationships.[1]


Examples of finish-to-start dependencies include

  • The cookie dough must be mixed before it can be cooked.
  • The truck needs to arrive before you can begin loading it.
  • The operating system has to be installed before the application.
