in this blog, we look at the various characteristics and benefits of network diagrams in project management. the project network is similar to a flow chart. network diagrams are used by project managers to track the progress of activities during the course of the project. the network diagram also shows how an activity relates to the other and the sequence of activities to be conducted. the precedence of activities as shown in the diagram is important, as some activities have to be completed before the next one starts. all activities must be identified and estimated as leaving even one task out from the network diagram can cause a cascading effect on the projected schedule, commitments, resource allocation and cost of the project.
the order of activities or their precedence is represented by circles that are connected by arrows.the diagram may also contain dummy tasks that are used to show the inter-dependency between tasks. for example, an arrow can be used to show that an activity cannot start before the completion of its predecessor or if both activities can be started simultaneously. a well-done network diagram smoothens out the project path and ensures early identification of issues and bottlenecks. the following information must be at hand before the network diagram is created: network diagrams when created accurately can bring in a whole lot of benefits. by providing a diagrammatic representation of the events, activities, structures, and processes, the network diagram helps all those associated in the project to understand the project at a micro level. pmp is a registered mark of the project management institute, inc. capm is a registered mark of the project management institute, in

the precedence diagram method enjoys heavy use in today’s project management circles and is considered to be a more efficient method for adms. the graphical evaluation and review technique is a network chart that’s been around for more than half a century. project managers can calculate the probability of repeating an activity. it is very important to develop the network diagram before proceeding with the project work. so now, you can see how important this tool is for a project manager in accomplishing the project’s goal. the bottom line is a project manager should prepare a good network diagram so that it shows the right path for project success. she has done her masters in journalism and mass communication and is a gold medalist in the same.
