A(n) _____ determines the early start and early finish dates for each activity in a project.

A(n) project network diagram determines the early start and early finish dates for each activity in a project. This diagram visually represents the sequence of project activities and their interdependencies, allowing project managers to identify the critical path and the timeline for project completion.

The early start date (ES) is the earliest time an activity can commence, while the early finish date (EF) indicates when an activity can be completed if it starts at the earliest possible time. By analyzing the network diagram, project managers can calculate these dates using forward pass techniques, which systematically determine the earliest times based on the project's activities and their durations.

Moreover, having this information helps in effective resource allocation, scheduling, and identifying potential delays. Understanding early start and finish dates supports proactive project management practices, ultimately leading to a more organized and efficient project execution.
