Guide to Understanding and Applying Project Network Diagrams

What is the Project Network Diagram?
The Project Network Diagram is a graphical depiction of the sequence and dependency of the different tasks in a project. It aids in effectively planning, organizing, and administering the different tasks involved in a project.

Why is it Important?
The Project Network Diagram is essential in project management as it provides a clear visual of the project timeline and sequence, identifying the earliest and latest that each task can start and finish without making the whole project late. It also helps in identifying the critical tasks that could potentially delay the project if not completed on time.

How does it Work?
The Project Network Diagram works by identifying and connecting all tasks needed to complete a project, with arrows showing dependencies and sequence between tasks. The direction of arrows indicates the flow and sequence of tasks, leading from the start to the finish.

Answering Questions on Project Network Diagrams in An Exam:
Here are some tips for answering questions on Project Network Diagrams in an exam:
- Understand the process of Project Network Diagrams thoroughly. Familiarise yourself with terms like 'Lead time', 'Lag time', 'Critical Path' and 'Float'.
- Use the diagram to determine the sequence of tasks, the critical path, and the estimated time for the project.
- Don't forget to analyze any changes in task times, task sequences, or dependencies.
- Be prepared to draw a basic project network diagram; it might earn you some good points.
- Always practice solving problems based on Project Network Diagrams, as the concept is better grasped when practiced.
