What is represented by nodes in a project network diagram?

In a project network diagram, nodes are primarily used to represent tasks or activities. This visual tool helps project managers to depict the sequence of tasks required to complete a project and illustrates the dependencies between these tasks. Each node indicates a specific activity that will be carried out, allowing the team to understand the workflow and critical path of the project.

By representing tasks as nodes, project managers can easily identify how each activity is connected, when it starts and ends, and how delays in one task can potentially impact others. This structure is fundamental for effective project scheduling and resource allocation, as it provides a clear overview of what needs to be done and in what order.

While milestones can be represented in a project network, they are typically shown as markers rather than the activities themselves. Resources refer to the people, tools, or materials needed to complete the tasks and are not represented by the nodes themselves. Stakeholders, being individuals or groups with an interest in the project, are also not depicted by these nodes in the network diagram. Instead, they are usually discussed separately in project documentation.
