- Suppose you are the project manager for the following project: First, draw a network diagram for the project. Determine the critical path and slack times for all of the tasks. This completes your plan for the project schedule. During project execution, you become aware of the need to change the duration of Task 4 to five days. Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects do these changes have on your project? What would have happened if you had not been monitoring the status of the project?arrow_forwardDave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Dave's earliest start (ES) and earliest finish (EF) are: Dave's latest start (LS) and latest finish (LF) are: Activity A B C D Time (weeks) 7 6 2 2 Immediate Predecessor(s) A A Activity A C D F G H Activity H Time Activity (weeks) E 4 F 6 G 10 H 6 ES 0 0 7 7 6 6 10 12 LS 14 EF 7 9 1228 10 20 LF Immediate Predecessor(s) B B C, E D, F 27arrow_forwardThe following is a table of activities associated with a project at Rafay Ishfaq's software firm in Chicago, their durations and what activities each must precede: Duration (weeks) Precedes B, C F E F This exercise contains only parts b, c, and d. b) The activities on the critical path are c) The total project completion time for Rafay Ishfaq's software firm is d) Determine the slack time for each of the activities.
