What is State Machine Diagram?

A state machine (also called, state chart, state tradition diagram, or simply state diagram) is a behavior which specifies the sequence of states an entity visits during its lifetime in response to events, together with its responses to those events. Typically, it is used for describing the behavior of classes, but state charts may also describe the behavior of other model entities such as use-eases, subsystems, operations, or methods.

How to draw State Machine Diagram?

  1. Identify objects or entities that need state diagrams
  2. Identify the states of the entity
  3. Define hierarchy of states, sub-states, orthogonal regions
  4. Link states and sub-states with transitions
  5. Add pseudo-states (i.e. entry point, exit point, choice join, fork junction, end etc.)
  6. Specify details of states and transitions using complete and appropriate notation
