Question $4$

$($Marks: $20)$

Given the following project activities, their predecessors, duration, and resource estimates answer the following questions:

$\backslash$table$[[$Activity Number,Predecessor$($s$),$Duration $($Days$),$Resources $($People$)],[$A$,,1,2],[$B$,$A$,4,2],[$C$,$A$,5,2],[$D$,$B$,$ C$,3,1],[$E$,$D$,1,3],[$H$,$F$,$ G$,3,2]]$

Q$\mathrm{.}4\mathrm{.}1$ Draw a graph of the resource loading for this project based on the earliest start

$(10)$

times of the activities. $($Graph does not need to be correctly scaled but must clearly show resource levels, fluctuations, and durations of usage$)$

Q$\mathrm{.}4\mathrm{.}2$ Without extending the project duration, draw a graph of the levelled resource

$(10)$

loading $($Minimise resource usage and fluctuations$).$ Briefly explain why the levelled resource loading diagram makes sense and list the activities that were affected and how the overall resource loading has changed along with why certain activities should not be moved regarding resource load levelling.
