f 5 b,d

g 3 c

h 4 f,g

i 2 e,h

a) Construct the network diagram

b) Find each activity's ES,EF,LS, and LF

c) Identify all paths. Which path is the critical path?

d) Calculate the slack for each activity

e) How long will it take to complete the project?

1) Complete exercise 4 "by hand" (without using MSP). Draw the network diagram and calculate your critical path and completion time.

2) Create a Microsoft Project (MSP) Gantt Chart for the problem above. How do MSP's answers differ (if at all) from your manual computations in Part #1 of this assignment? (Note: See syllabus if you have not downloaded Microsoft Project yet. We will be using the program for the rest of the term).
