How do you begin to draw a directed network?

To begin drawing a directed network, focusing on the activities and their relationships is essential. Connecting activities with no predecessors to the start effectively establishes a foundation for the network. This is because activities without predecessors are the initial tasks that need to be completed before moving on to subsequent ones. By linking these activities directly to the start node, you create a clear starting point from which all other activities will branch out.

Setting up this initial connection is crucial for accurately representing the flow of activities within the network. It provides a structured approach that allows for the identification of dependencies and the overall sequence of actions needed to complete a project or process.

The other choices do not establish the correct starting point for creating a directed network. For example, starting from the last activity can lead to confusion about the sequence of events. Connecting activities directly to the finish overlooks the necessary steps that lead up to that final outcome. Labeling edges with weights, while important for showing the costs or durations associated with the activities, does not address how to correctly begin the network layout.
