. Part 1: Project Scheduling using the Critical Path Method Using the project activity data listed in Table 1: Project Activities and using pen or pencil and paper: ? Draw a network diagram for the project using the precedence diagramming method (PDM) and the following node notation format:

ES ID EF TS FS LS Dur LF ES = Early Start ID = Activity ID TS = Total Slack FS = Free Slack LS = Late Start Dur = Duration EF = Early Finish LF = Late Finish ?

Do forward and backward pass calculations and indicate the early and late start and finish times. ? Indicate the critical path. ? Indicate the total and free slack of each activity.?

Include a readable scan or photo of this drawing in your submission. ? Check your work with a computer-based project scheduling tool such as Microsoft Project (see Meredith et al, 2017, pp. 152-154). Include a screen shot of this check or the MS Project file with your submission.
