The following represents a very simple project. The calendar allows for 5 work days (M-F) per week. To keep things simple we won’t separate capital expenses and labour. The cost per activity shown below is total (i.e. not per day). Activity Duration (days) Precedent Cost A 5 None* $500 B 7 None* $1000 C 3 A , B $400 D 4 C** $500 E 6 C** $800 * Except for ‘Start’ ** The project can only be signed off once D and E have been completed. Enter the data into a software tool such as GanttProject, and generate the Gantt chart. Please ensure that: 1.…
Dave 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.
