3. You are given the activity information below and the activity-on-node precedence diagram for a project at your company. 16 points (-4/error) a) Determine the critical path and its duration. What is your initial estimate for project completion time? Show your work on the next page. b) Fill in the table on the next page to determine the earliest start (ES) time, the earliest finish (EF) time, the latest start (LS) time, the latest finish (LF) time, and the Slack for each project activity. Slack =LSES or LFEF. Note: This precedence diagram is posted as a separate pdf also. Problem 3 continues on the next page. a) Fill in the table with each path and show your work by calculating the time for each path in the table to determine the critical (longest) path(s). Add/delete rows in the table as needed. You must indicate the critical path and the estimated project completion time below the table. 5 a) Fill in the ES \& EF times in the table below working from Start to Finish. Then, fill in the LS \& LF times working backwards from Finish to Start. After determining the ES, EF, LS, \& LF times, calculate the Slack time for each activity using both Slack = LS - ES and Slack = LF - EF. Note: Both 3.
