What is Activity Diagram?

Activity diagrams illustrate the flow of functionality in a system. They are often used in business modeling to show the business workflow. Activity diagrams may also be used in requirements gathering, for example, to illustrate the flow of events through a use case. These diagrams define where the workflow starts, where it ends, what activities occur during the workflow, and in what order the activities occur. An activity is a task that is performed during the workflow.

Guidelines for creating Activity Diagrams

  • Minimize the number of crossings links or relationship among activities.
  • Reorganize larger diagrams into several smaller ones. It is often easier to have several diagrams on various levels of detail than a single complex one.

  • It can be used to elaborate the logic of an entity in UML, such as, a use case, function or orchestration of several use cases and etc.
