What is the primary focus of transition actions in a state transition diagram?

In a state transition diagram, transition actions primarily focus on defining the movement from one state to another based on specific events. These actions are triggered by occurrences (or events) which dictate how the system reacts and moves through various states.

When an event takes place, it can lead to a transition that may result in certain outputs or actions being performed. The output results reflect the response of the system after the transition has been activated. This concept emphasizes how the system behaves in response to state changes and directly ties into the system's functionality.

States are significant as they indicate the conditions or situations of the system, and events summarize what triggers changes; nevertheless, transition actions specifically highlight the outcomes and system behavior that follow these events, solidifying their importance in understanding the overall operation of the system.
