Question $1$:

Refer to the network below

Baseline schedule

$\backslash$table$[[$Activity$,$Duration,IPA,ES$,$EF$,$LS$,$LF$,$TF$,$FF$],[$A$,6,-,0,6,0,6,0,0],[$B$,2,-,0,2,1,3,1,0],[$C$,9,-,0,9,11,20,11,0],[$D$,4,$A$,$ B$,6,10,6,10,0,0],[$E$,7,$B$,2,9,3,10,1,1],[$F$,5,$D$,10,15,15,20,5,5],[$G$,10,$D$,$ E$,10,20,10,20,0,0],[$H$,8,$C$,$ F$,,20,28,20,28,0,0],[$I$,3,$C$,$ G$,20,23,25,28,5,5],[$J$,2,$H$,$ I,$28,30,28,30,0,0]]$

Fifteen days after the start of the project, the following information is received.

Activity A Completed $2$ days later than planned

Activity B Completed on time

Activity C Started; $4$ days left

Activity D Completed; took $5$ days to finish

Activity E Completed

Activity F Canceled

Activity G Started $3$ days late; project manager hopes to cut $1$ day of its duration

Activity K Added: Duration $=4$ days. IPA $=C$

Activity L Added: Duration $=3$ days. IPA $=K,G$

Activity I Adjusted: IPA $=$ L

Draw the updated network. Calculate the new project completion date. Check if there are changes to the completion date and$/$or to the critical path. Mention the causes for such changes, if any.

Rubric:

New network based on the new information received after $15$ days $($Correct calculations, professionally done$)=70$ points

Mention if critical path changes or extended $=15$ points

Write causes for change in critical path or extension in the critical path $=15$ points
