Workflow and activity diagrams symbols9/15/2023 ![]() ![]() The symbol represents the end state of an activity and indicates that the flow of a process has been completed. ![]() The join symbol is a representation of two concurrent activities that join into one activity flow. The symbol represents a split in a single activity flow into two concurrent activities. The symbol visualizes a decision node in the diagram and has at least two paths branching out of the symbol with conditions that provide information on the flow. They represent the activities that are modeled in the process. The activity symbol is represented by a box that has rounded edges. The arrows visualize the flow of one action to another. The symbol represents the beginning or start point of a process or workflow in the activity diagram. Activity Diagrams Symbols and NotationsĪctivity diagrams have specific UML symbols that help concisely visualize the items and the flow of the action. This helps teams ensure that all necessary tasks are accounted for and that the workflow is efficient and effective. The diagrams are typically used before the start of the project to help model important workflows, during the discovery or requirement phase to illustrate the flow of events on specific use cases, and during the analysis and design phase where they define the behavior of operations.Īctivity diagrams show the different steps involved in a process, as well as the decisions that need to be made along the way. They are similar to flowcharts because they provide a visualization of the flow between actions in an activity or process. What are Activity DiagramsĪctivity diagrams are used to represent and document the business and software processes as a progression of actions. In software development, UML is used to visualize projects and is used in activity diagrams and sequence diagrams. Universal Modeling Language (UML) is used to ensure that there is a common, semantically and syntactical modeling system that consists of diagrams and visual graphics that will help developers and stakeholders understand, visualize, construct and document software applications and systems. Understanding Universal Modelling Language ![]() These diagrams help teams visualize the workflow and interactions of their system, providing a common language for all team members to use when discussing and aligning product and technical requirements. Activity and sequence diagrams are essential tools in the software development process. ![]()
