Based on the predecessor table below, 1) complete the network diagram with ES, EF, LS, LF dates, and float for each activity and 2) identify the project's critical path. Follow the network diagram format that we used in class. ID Description Predecessor Duration (days) A Define scope None 2 B Document requirements A C Analyze & design prototype B D Buy materials C E Build prototype C 6 F Implement prototype D, E G Test prototype F 4 H Present prototype to customer G 2 1. Forward pass: determine ES, EF Legend A 2. Backward pass: determine LS, LF Task ID Duration 3. Calculate float/slack & identify critical path o Float = LS - ES ES EF LS LF Float B D G F F H The critical path is: ; length of the critical path is days
