Hand or if you work in smaller, less complex projects, you can also use standard The software is then able to draw the diagram and determine the optimal sequence of activities. the list of activities, logical relationships and leads and lags, are the same and need to be provided by the user. However, the input data requirements, i.e. In projects that use scheduling software to support the project management, such diagrams are usually created by the software. (AOA) method to develop your schedule network diagram, you draw activities as Waiting time for activities, referred to as slack or float, can also Of an activity as well as references to work packages or the work breakdown SS, FS), whether it is required or discretionary, leads and lags, as well as other data relevant for your scheduling, andĪctivities include the earliest start and latest finish date, the criticality Add details to each relationship, such as the type of dependency (e.g.Connect the activities with arrows that represent the type of logical relationships (as explained in our article on the precedence diagramming method),.Insert activities on the (future) nodes of your diagram, including details and additional data (see explanation below),.To draw a schedule network diagram (in line Relevant inputs of the schedule network diagram are the list of defined activities, the estimated durations of these activities and the logical relationships among them (also referred to as dependencies). Project Schedule Baseline: Definition, Purpose, Example How Do You Create a Schedule Network Diagram? the chain of activities with the longest duration. They are the basis to identify the critical path, i.e. Schedule network diagrams are also used to document the slacks and floats and the leads and lags of activities. Schedule, other ways of presentation (such as Gantt diagrams) and a moreĪggregated view tend to be more common than schedule network documents in many Larger projects, however, it is often a rather detailed and complex workingĭocument that links the dependencies and sequences of all activities to the In a project, you can also use this type ofĭiagram to discuss sequences and dependencies, as well as for the stakeholder communication. Such as the schedule network analysis or the critical path method (PMBOK®, ch. Management’ knowledge area where it is served as an input for other scheduling techniques, What Is A Project Network Diagram Used for?ĭevelop and document the sequence of activities. These are characteristics of the timing and scheduling of activities that we are explaining in detail in this article. examples, in this introduction to the predecessor diagramming method.Īpart from dependencies, a project schedule diagram can also show leads and lags. In a finish to start dependency, for instance, the predecessor must have finished for the successor to start. The first part of these terms indicates the status the predecessor activity must obtain before the successor activity can have the status referred to in the second part. With information about the type of logical relationship between activities. The diagram is based on and often enriched Hope this helps! Let me know if you have any additional questions.Example of an Activity-on-Arrow Project Schedule Network Diagram.Ī technique to create project schedule network diagrams is the precedence diagramming method which we are explaining in this article (incl. To learn more about our sequence markup tool functionality, I would recommend reading through our UML Sequence Markup article from the Lucidchart Help Center. So make sure to only ungroup the objects and adjust your lines/shapes after you have completely finished building your diagram and no longer need to make changes to the markup. However, keep in mind that once you ungroup your sequence diagram, you won't be able to edit the makeup again. Ungrouping your auto-generated UML diagram will allow you to move elements around as well as style them as if they were on a regular diagram. To do that, select your diagram > right click > select "Ungroup" from the drop-down. As a workaround, you can manually adjust those lines by ungrouping your diagram. Thanks for posting in the Lucidchart Community! Unfortunately, when auto-generating a sequence diagram, it is not possible to change the spacing between the lines and the bottom/top of the activation shape using additional markup.
