Assume you have compiled the steps needed to complete a project as noted below. You have identified all relevant steps and have made some determination regarding predecessor$/$successor relationships. Suppose that you have defined duration estimates to each of the activities as shown in the table. Recreate the Network diagram for this project and note how MS Project uses nodes to identify activity durations, start and finish dates, and predecessors. What is the critical path for this network diagram? How do we know?
