Using Visio and/or Project, (contact Nishit Derade tuk05160@temple.edu for help obtaining and/or installing) or any other drawing tool of your choosing, create a PDF and upload to Canvas in Assignment Unit#4.3 with the following:
3.A Draw a network diagram for the activities
3.B Calculate the earliest expected completion time
3.C Show the critical path
3.D What would happen if activity 6 were revised to take six weeks instead of two weeks?
3.E Construct a GANTT chart for the project (with tasks as specified in the table above)
3.F Look again at the activities and create a new diagram that is updated to reflect the following: Your team is in first week of the project and has discovered that each of the activity duration estimates is wrong. Activity 2 will take only one week to complete. Activities 4 and 7 will each take three times longer than anticipated. All other activities will take twice as long to complete as previously estimated. In addition, a new activity number 11 called “Stabilization” has been added. It will take one week to complete, and its immediate predecessors are activities 10 and 9. Adjust the network diagram and recalculate the earliest expected completion times.
