What does a Project Network Diagram depict in a project?

1. A visual representation of project costs

2. A summary of team responsibilities

3. Activities and their precedence relationships

4. A timeline of project completion dates

The correct answer is: Activities and their precedence relationships

A Project Network Diagram is a crucial tool in project management, as it visually illustrates the sequence of activities and their precedence relationships. This representation helps project managers understand the order in which tasks must be completed, allowing for effective scheduling and resource allocation. By showing how activities interrelate, the diagram helps identify critical paths, which are the longest stretch of dependent activities and determine the shortest time to complete the project. Understanding these relationships is essential for efficient project execution, as it aids in pinpointing potential bottlenecks and informing decisions regarding task prioritization and resource allocation. Other options, such as representing project costs or team responsibilities, address different aspects of project management but do not provide the specific focus on activities and dependencies that the Project Network Diagram emphasizes. Similarly, while a timeline of project completion dates is important for overall project scheduling, it does not convey the intricate relationships between activities that are fundamental to planning and executing projects effectively.
