#$1$

Consider the following project.

$\backslash$table$[[$Activity$,$Predecessor$($s$),$Duration $($days$)],[$A$,-,3],[$B$,-,2],[$C$,$A$,5],[$D$,$B$,5],[$E$,$C$,$ D$,4],[$F$,$C$,$ D$,3],[$G$,$E$,$ F$,3]]$

Develop the project schedule using the critical path method, indicating the early start, early finish, late start, late finish, and slack for each activity. What is the project duration, and which activities are critical? As a hint, note that both activities A and B have no predecessor activities. You do not need to draw the project network diagram.

#$2$

Consider the following project.

$\backslash$table$[[$Activity$,$Predecessor$($s$),$Duration $($days$)],[$A$,-,4],[$B$,-,3],[$C$,$A$,$ B$,5],[$D$,$B$,4],[$E$,$C$,4],[$F$,$D$,$ E$,7],[$G$,$E$,6],[$H$,$F$,$ G$,4],[$I$,$D$,9],[$J$,$G$,$ I,$6]]$

Develop the project schedule using the critical path method, indicating the early start, early finish, late start, late finish, and slack for each activity. What is the project duration, and which activities are critical? As a hint, note that both activities A and B have no predecessor activities, and both activities H and J have no successor activities. You do not need to draw the project network diagram.
