The following portion of a WBS (work breakdown structure) project plan lists the project tasks (labelled by letter), the tasks on which they are dependent, and their estimated duration (in days). You can assume Saturday and Sunday are not work days for the project.

(i) Using the information given, create a Pert chart, clearly indicating the dependencies on the Pert chart and mark the critical path on the chart. Show your workings.

\begin{tabular}{|c|c|c|} \hline Task Name & Dependency & EstimatedDuration(days) \\ \hline A & None & 3 \\ \hline B & None & 5 \\ \hline C & A & 3 \\ \hline D & A, B & 5 \\ \hline E & C & 4 \\ \hline F & C, D & 5 \\ \hline G & E & 3 \\ \hline H & G & 4 \\ \hline \end{tabular}
