path should also be determined. Here are the activity times:

$\backslash$table$[[$Activity$,$Time $($weeks$)$ Immediate Predecessor$($s$),$Activity,Time $($weeks$)$ Immediate Predecessor$($s$),,],[$A$,5,-,$E$,5,$B$],[$B$,8,-,$F$,6,$B$],[$C$,2,$A$,$G$,10,$C$,$ E$],[$D$,2,$A$,$H$,7,$D$,$ F$]]$

Dave's earliest start $($ES$)$ and earliest finish $($EF$)$ are:

$\backslash$table$[[$Activity$,$ES$,$EF$],[$A$,0,5],[$B$,0,8],[$C$,5,7],[$D$,5,7],[$E$,8,13],[$F$,8,14],[$G$,13,23],[$H$,14,21]]$

Dave's latest start $($LS$)$ and latest finish $($LF$)$ are:

$\backslash$table$[[$Activity$,$LS$,$LF$],[$H$,16,23],[$G$,13,23],[$F$,10,16],[$E$,8,13],[$D$,14,16],[$C$,11,13],[$B$,0,8],[$A$,6,11]]$

The slack times are:

$\begin{array}{cc}\text{A}\text{c}\text{t}\text{i}\text{v}\text{i}\text{t}\text{y}& \text{S}\text{l}\text{a}\text{c}\text{k}\\ A& 6\\ B& 0\\ C& \end{array}$
