$($i$)$ Use the information in the table above to draw a precedence network $($PERT$).$ Each activity node should contain: Activity label, Duration, Earliest start $($ES$),$ Earliest finish $($EF$),$ Latest start $($LS$),$Latest finish $($LF$)$ and Float $($use the British Standard BS $4335$

labelling convention$).$

Show all calculations. Justify your estimates for activities B$,$ H and K$.$

$($ii$)$ Identify the critical path of the activity network you created in part $($i$)$ above. Based on the given estimates, what is the minimum time required to complete the above project?

$($iii$)$ Explain in detail, $5$ different measures a project manager could take to reduce the duration of the above project and discuss their overall impact on the project.
