What is a State Diagram?

State Diagram is a Unified Modelling Language (UML) diagram type in computer science. It is used to describe how a system behaves when an event is observed by considering all the possible states, transitions, and actions of an object.

How to Create a State Diagram?

  • Understand the requirement for you to illustrate a state diagram and get familiar with all the possible scenarios to cover.
  • Use a platform where you can visualize the state diagram. Creately’s template and shape libraries consist of a wide range of frameworks and UML components for you to either quickly get started or to draw from scratch.
  • Determine the initial state, which can be represented by a dark circle, and the final terminating state, which can be represented by a bordered circle.
  • Use arrows/lines to highlight the transitions of control from one state to another by connecting the source and the target.
  • Label the events which trigger these transitions. An event that causes a change in state can be represented by arrows labelled with its label.
  • Establish guard conditions to ensure transitions are appropriate and relevant. A guard condition forces the transition to be checked against that condition before going ahead.
  • Share the state diagram with your teammates via a link,or invite them to a video/audio conference call.
  • Present the state diagram and mark the discussions via in-line comments and shape data properties in real-time.
  • Refer to the version history to identify the changes made by other collaborators and revert to any iteration of changes.
  • Once finalized, share the state diagram with access controls, or export with high quality as a SVG, PNG, JPEG, or PDF.
