Key Terms

• ?Task Dependencies The relationship between two
  tasks in a project
• ?Critical Path The tasks that must be completed
  by the given schedule dates in order for the
  overall project to be completed in the shortest
  amount of time
• ?Slack The amount of time that a task may be
  delayed from its scheduled start date without
  delaying the entire project
• ?lag time A period of time imposed on a
  relationship between tasks
• ?Positive Lag Time When a project is scheduled
  from a Start Date, moves the second of the two
  related tasks forward in time
• ?Negative Lag Time When a project is scheduled
  from a Start Date, moves the second task of two
  related tasks backward in time AKA lead
  time

Task Dependencies

• ?Finish-to-Start (FS)
• Task 1 must finish before task 2 can start
• ?Start-to-Start (SS)
• Task 1 must start before task 2 can start
• ?Finish-to-Finish (FF)
• Task 1 must finish before task 2 can finish
• ?Start-to-Finish (SF)
• Take 1 must start before task 2 can finish

Key Take-Away

• ?4 Types of Task Dependencies
• Finish-to-Start Start-to-Start
• Finish-to-Finish Start-to-Finish
• ?Most common type of task dependency
• Finish-to-Start
• ?Critical tasks appear within a red border shape
  in the Network Diagram view
• ?Non-Critical tasks appear with a rounded
  rectangle in the Network Diagram view. The border
  is blue, and the interior is light blue

Key Take-Away

• ?When scheduling is done from a project Start
  Date, positive lag always pushes the 2nd task
  forward in time
• ?When a project is scheduled from a Start Date,
  applying negative lag time to task dependencies
  that are on a critical path is a common way to
  shorten the critical path because it brings the
  second task backward in time, causing the tasks
  to overlap
• ?When a project is scheduled from a Finish Date,
  all tasks have as late as possible schedules and
  lag time affects the first task rather than the
  second
• ? Positive lag time always increases the amount
  of time between tasks and pushes the first task
  backward in time
