Assume you have a project with seven activities Labeled A-G, as shown below. Derive the earliest completion time (or early finish time - EF), the latest completion time (or late finish - LF) and slack for each of the following tasks (begin at time =0).
Which tasks are on the critical path? Draw a Gantt Chart for these tasks.
Draw a Network Diagram for the tasks. Highlight the critical path.
Even guidance on drawing Gantt Chart and Network Diagram will do.
