6A. Draw the Network Diagram, and identify and discuss the project duration and the
critical path using the following activity notation
ES
SL
LS
ID
EF
ANSWER:
SL
Time LF
First: Draw the precedence diagram.
You can draw the diagram using any software tool and paste it on this area OR you can draw the diagram by
hand on a clean white paper and take a picture to paste it in this area.
Second: Using the notation given identify the duration of the project. THIS PART MUST BE TYPED
If typing is difficult then it can be drawn by hand using the instructions given in the First step above.
Third: identify the critical part and explain the critical path.
Fourth: Explain your answer. This can be done by describing the process and the observations done once the
answer has been found.

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
