• Presedence Tables can be used to show which activities must be completed before another activity starts.
• When another activitiy cannot start until another activity is completed it is called a dependency
  
  

  

• On Activity Networks (also called arc networks), the arcs are referred to as activities, and the nodes represent the completion of the task.
• Each arc/task is labelled with a letter to represent it and the arrow is used to define the direction. The nodes are numbered starting from 0 (or 1).
• The first node is called the source node.
• You have to number each node as it is added to the network.
• The final node is called the sink node.
  
  
  YOU CANNOT HAVE TWO ACTIVITIES WITH THE SAME START/FINISH NODE
