Network diagrams will help you to ensure that project activities are delivered on time, on budget, and to the quality and scope defined in your Work Breakdown Structure.
You should develop Network Diagrams for three key areas and reasons: 1) to define and sequence activities, 2) to help you estimate the resources that you will need, and 3) to enable you to work out how long each activity will take.
Invest time here, and you will have outlined how project activities relate to each other, and know when and where project resources will be required. You will have the overview that you need to go on to develop accurate schedules and Gantt charts – and ultimately to manage your time, costs and resources effectively!
