  1. Draw an Activity-on-Arrow (AOA) network diagram representing the project. Put the node numbers in circles and draw arrows from node to node, labelling each arrow with the activity letter and estimated time.
  2. Identify all the paths on the network diagram and note how long they are.
  3. What is the critical path for this project and how long is it?
  4. What is the shortest possible time it will take to complete this project?
