Ein Aktivitätsdiagramm (englisch activity diagram) ist ein Verhaltensdiagramm der Unified Modeling Language (UML), einer Modellierungssprache für Software und andere Systeme, und stellt die Vernetzung von elementaren Aktionen und deren Verbindungen mit Kontroll- und Datenflüssen grafisch dar. Get Visual Paradigm Community Edition, a free UML software, and create your own Activity Diagram with the free Activity Diagram tool. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities. In this set of tasks, the sequence or the order of the tasks is quite important. Activity diagram is an advancement of a flowchart that contains some unique capabilities. I previously created a use case diagram to get a rough idea of what actions were needed. Draw Diagram. Create New . In this diagram, activities (tasks) are presented by the arrows. Activity diagrams can be drawn at different levels of formality, from a Basic Flow Chart style of diagram used to represent a simple Business Process to a sophisticated Action-based diagram that can be used to model a complex system. Draw your activity diagram by using this one as a starting point. There are many tools that can be used for drawing project activity diagrams.

Make sure all your tasks have the same granularity. Activity diagrams can express complex control logic better than sequence diagrams and state machine diagrams. Activity diagrams, along with use case and state machine diagrams, are considered behavior diagrams because they describe what must happen in the system being modeled. Start using draw.io. When it comes to a project, the entire project is divided into many interdependent tasks. The early tasks will be at the left hand side and the tasks performed at the later part of the project execution will be at the right hand side. See what’s possible with draw.io diagrams. That includes the modelling of consecutive or parallel steps in an process. The Unified Modeling Language includes several subsets of diagrams, including structure diagrams, interaction diagrams, and behavior diagrams. Activity nodes also include flow of control constructs, such as synchronization, decision, and concurrency control. All feedback is important to us. Unified Modelling Language (UML) provides you with a variety of diagramming tools, some to detail information structure, and some to detail behaviour. Your extra feedback is important to us. Inner elements are displayed on the Activity diagram pane automatically upon creating the first diagram under the Activity element. Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency.

Use these template diagrams as a starting point for your own diagram. Regardless of the medium used, the process of creating the activity diagram remains the same. An activity diagram is particularly good at expressing the flow of objects—matter, energy, or data—through a behavior, with a focus on how the objects can be accessed and modified in the execution of that behavior during system operation. Activity diagrams are mainly used as a flowchart that consists of activities performed by the system. Flowchart Maker and Online Diagram Software. Subscribe to our newsletter.
