Please draw the AON diagram using the dependency matrix below Predecessor activity (upstream) Successor activity (downstream)

Answer 1

Network diagram refers to the sequence of how the activities will be performed and arrange the activities in sequence and how they are dependent on one another. So, the statement, "Network diagrams illustrate the technical constraints among activities," means the activities are constrained because one activity cannot be started until the predecessors are finished.

Network diagram is important in project management because it helps in planning and tracking the project from start to end. This also represents the critical path and the scope of the project. Critical path activities refers to the tasks in project that should start and end in time to end the project on schedule. Slack time refers to the time by which a task can be delayed without affecting the another task or completion of the project. so, activities on critical path exhibit zero slack time.
