The following table shows activities with duration, dependency, dependency type, and the number of workers from one small segment of a project network. Draw the segment of the network diagram and then: (a) Show the resource usage (chart) if activities A, B, and C start on day one; (b) Show the new network diagram and the resource usage (chart) when resources are leveled after applying appropriate slack times.

Draw a neat network diagram and find the critical path for the given activity table for software development. Activity Description Predecessor Duration A Analysis None 2 B Development None 6 C Testing None 4 D Documentation A 3 E Training C 5 F Implementation A 4 G Maintenance B, D, E 2   a)    Draw a neat network diagram and find LS,LF,ES,EF and mark appropriate Activity on Node. b)    Find the completion time of the project. c)    Find critical path. (calculation of ES, EF, LS, LF)
