Below is information about a project to implement a new manufacturing cell to assemble personal digital assistant devices. Assume 5-day week. a. Draw an activity-on-node (AON) network. You may submit a hand-drawn version or use a tool of your choice to draw the network diagram or (8 points) b. Identify the Early Start, Early Finish, Late Start, Late Finish, critical path, total float and free float using the critical path algorithm. (ES - 1 point, EF - 1 point, LS - 1 point, LF - 1 point, critical path -1 point, total float and free float -1 point =6 points) c. Which of these tasks should the project manager track most closely? (4 points) d. Where do you see potential errors in network logic? Explain your reasoning. (4 points) e. What would happen if a new estimate for Task D increases its expected duration from two weeks to six weeks? Would the project take longer? Would anything else change? Explain you answer. (3 points)
