Follow-up Question

6C. Change the time of at least two activities that can reduce the overall project duration, draw the new critical path and the new Gantt chart.

First: Repeat 6B by changing the task time of any 2 or 3 tasks that will result in a smaller project duration.

Please note that changing only terminal tasks (ending tasks) will not give you any credit as it is easy to reduce the duration of the project by changing the duration of the last task.

To make the reduced task time more visible you can colour them RED and write about them.

Second: identify the critical part and explain it. Explain if the critical path has changed and why? or why not?

Third: Explain your answer for the new (shorter) project duration. This can be done by describing the process and the observations done once the answer has been found.

Fourth: Draw the new project’s Gantt chart

Fifth: Explain the Gantt chart by emphasizing the observations made. State your conclusions.

thank you
