A Project Management Network Diagram Example
A network diagram is a graphical representation of the project and is composed the inter-relationship between the activities involved in the project. And in maximum cases, you cannot begin the next process in any of the. Network diagram controls the scheduling, control and monitoring of projects. The effective project management can easily find out thanks to this technic, which whether the real time of the project process corresponds the planned one. This article takes a look at project management network diagrams. than depict a dependency between two items, these arrows depict a logical relationship.
This is a useful feature of a network project diagram as it prepares both the project team and stakeholders for the worst. The team would have to decide on the longest possible amount of time that each node could take.
After adding these values, the longest duration a project could take is produced and is seen as the most pessimistic outcome. Benefits of network diagram in Project Management?

Network diagrams are useful in project management in many ways. Some of the benefits of using network diagrams include: Network Diagrams help validate the time estimation for your project: Networkdiagrams paint a clear picture of how varying tasks fit in to a project and their specific interdependencies. This allows for useful duration estimation. Through the development of a critical path and the activities that lie on it, a rather accurate project duration is produced and can be used to communicate to stakeholders.
Network Diagrams aid in planning, organizing and controlling: Due to the sequential visualisation of all project tasks and activities and all their dependencies, planning the project is an easier feat whilst being able to take into consideration the criticality of each task.
The snapshot of activities aids in how a PM organises the project. Cloud-based project management apps such as Sinnaps further aid in this area with a feature called Test-mode which allows PMs to produce various network diagrams before choosing the one that suits best. Task interdependencies are clearly defined: With the help of visual representation of project tasks, their dependencies, criticality and duration are all clearly defined. Activity workflow is defined: The critical path can change as critical tasks are completed more quickly than estimated or non-critical tasks are delayed.
Any task on the critical path is a critical task. We monitor these tasks regularly to see if any of them slip. If a critical task slips, so does our project finish date. We may want to view those tasks that currently can slip by only a day without affecting the critical path, because if they slip by more than a day, they will become critical tasks.
Project Planning Process – Network Diagrams
Viewing the tasks with float helps alert us to tasks that are becoming critical. For large and complex projects, there may be be hundreds of tasks and dependency relationships.
Without softwareit can be mighty difficult managing this. The validity of the diagram relies on the accuracy of the duration we assign each task.
For new types of projects this duration is not well known.
And associated with this concern is that we project managers are inclined to pay special attention to the tasks on the critical path. But sometimes a parallel path is almost critical and, when a delay occurs in one of the tasks, that path now becomes the sequence with the longest duration and the new critical path. In this case, our focus has been on the wrong tasks, and the project suffers a delay despite the fact that all tasks on the original critical path are on schedule.
Some further stuff A predecessor to an task is an task that determines when work on the next task can begin. We usually minimise task dependencies to avoid delays caused by one task waiting for another to be completed.
Although most tasks cannot start until their immediate predecessor task s is completed, in theory at least there are four possible relationships could between tasks: The predecessor must finish before the successor can start. The predecessor must finish before the successor can finish.
What is a project network diagram?
All network diagrams have the advantages of showing task interdependencies, start and end times, and the critical path the longest path through the network but the AOA network diagram has some disadvantages that limit the use of the method. The three major disadvantages of the AOA method are: The AOA network can only show finish-to-start relationships. It is not possible to show lead and lag except by adding or subtracting time, which makes project tracking difficult. There are instances when dummy activities can occur in an AOA network.
What is network diagram in Project Management?
Dummy activities are activities that show the dependency of one task on other tasks but for other than technical reasons. For example, one task may depend on another because it would be more cost effective to use the same resources for the two; otherwise the two tasks could be accomplished in parallel. Dummy activities do not have durations associated with them. They simply show that a task has some kind of dependence on another task.
