Here is the solution to your project management problem. Part (a): Prepare a network diagram for this project (use the AON format). In an Activity-On-Node (AON) diagram, activities are represented by nodes, and arrows show the dependencies between them. The network diagram connections are as follows: Start node connects to Activity A. Activity A connects to Activity B and Activity C. Activity B connects to Activity D. Activity C connects to Activity D. Activity D connects to Activity E. Activity E connects to Activity F and Activity G. Activity F connects to Activity H. Activity G connects to Activity H. Activity H connects to an
