Gantt Chart • Use the WBS and the Activity List to generate a Gantt Chart which shows

- The start and finish dates of the different activities - The overall time of the project - The dependency relationships between activities - The critical path and milestones

Activity on Node (AON) Network • Draw an Activity on Node (AON) network to represent the activities of your project

- Activities are represented by nodes - The dependencies between activities are indicated by arrows
