But what is a Network Diagram? Network diagrams tell if an activity will start before, after or at the same time with another activity. In this article, we are going to list the 6 benefits of using Network Diagrams.
What is an activity network diagram? An activity network project diagram is a diagram visual representation of all the sequential and dependent activities within a project. The relationships between all the activities are represented by arrow and nodes.
An example of an activity network diagram is any project with several activities as part of its process. Suppose a team is tasked with renovating a kitchen, an activity network diagram or project management diagram would list and portray all activities from buying materials to completing the final clean.
A team and PM create an activity network diagram that aids them in planning and organising all the activities in a project. The nodes boxes represent the activities and the arrows that connect them represent the flow and what activity follows the next. Some of the project process steps run in series, while others run in parallel.
Series represents activities that are sequential, but face dependencies. This means that one after the next cannot be started until the one preceding has been completed. The activities running in parallel face potentially having different completion times because they are dependent on the series of activities preceding.
The critical path goes through all the nodes with the longest expected completion times. In Sinnaps, the critical path is made clearly visible to users as it is highlighted at the top of the network diagram. Any activities that are running in parallel with the critical path must consider how long their completion will take and be on par with the critical path.
Most Likely Time Most Likely time defines the expected completion time of the project. Usually, it is defined and based on the critical path. Optimistic Time If a project team wished to know the fastest time in which they could potentially complete the project, they must decide on the shortest possible time for each of the nodes.
In this way, if they complete each node in its established shortest time, the project will be completed faster. This would be seen as the most optimistic outcome of the project.
Pessimistic Time A project team may also wish to see what the worst-case scenario would be in terms of project duration. 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: What activities are dependent on each other and what their sequence is is all represented by network diagrams.
Network diagrams such as those created on Sinnaps show which activities in the workflow have been completed and when, which are in process and which are left to be done.
Network diagrams identify opportunities to compress the schedule:Gantt Chart is for the creation of Gantt chart for project schedule. PERT Chart is invented to create PERT charts and timeline for project or task management, timetables, work breakdown structures, critical path method, project lifecycles, goal setting, schedules and agendas.
This article takes a look at project management network diagrams. Through images, it shows examples of network diagrams and describes the relatedness and parts.
A Guide to the Project Management Body of Knowledge (PMBOK ® Guide) explains process inputs and outputs in a graphical representation, but shows this individually for each process without connecting the processes in a knowledge area in one diagram.
Here’s a simple example that can help you learn how network diagrams can be useful in any project you manage.
