Assignment - Network Diagram Worksheet
Chapter 10 expands on activity networks and project scheduling techniques from chapter nine. Gantt charts are presented as an alternative to PERT, and Activity-on-Arrow (AOA) networks as an alternative to AON. Additional task relationships include Finish to Start, Finish to Finish, Start to Start, and Start to Finish. Methods to accelerate a project that is falling behind schedule include adding resources, fast-tracking, compromising quality, reducing the project's scope, and using overtime. Crashing links activities to their respective cost to determine the time/cost trade-off to accelerating the schedule. While activity networks are useful for planning the schedule, they can become too large or complex to be meaningful, they can be incorrect due to human errors or oversimplification, they are not suited for all tasks, and they can be problematic when used with subcontractors.
Learning Objectives:
1. Apply lag relationships to project activities.
2. Construct and comprehend Gantt charts.
3. Recognize alternative means to accelerate projects, including their benefits and drawbacks.
4. Develop activity networks using Activity-on-Arrow techniques.
5. Understand some of the important controversies in the use of project networks.

1. Draw the network as a Gantt chart.
2. What is the critical path? Which activities have slack time?
3. What would happen if activities B and D each took 5 extra days to complete instead of the expected duration? How would the critical path change?
