For the following precedence diagram, perform forward and backward pass calculations and determine the project duration. Highlight the critical path. Calculate the ES, EF, LS, LF, TF, and FF for each activity, and the link lag value for each link. Assume a Finish-to-Start (FS) relationship with zero lag/lead time unless otherwise shown.
SS=
Start-to-Start; FF = Finish-to-Finish; and SF = Start-to-Finish.
