This post describes state transition design.
State transition design is the design that determines what software functionality is implemented in which state. The key design points are the definition of states (functions) and transition conditions, and interface variables between states. The concrete process includes the following steps.
It also designs software architectures and software components based on their software functionality.
Step-1 Creating a state transition diagram
State transition diagrams visually represent and define software states and transition conditions. Complex situations are easier to understand if you organize them into a hierarchy.
Step-2 Create a state transition table
State transition tables ensure coverage of states and transition conditions by tabulating state transition diagrams.
Step-3 Create a table of variables for each state
Organize the variables used in each state in a table. If there are variables shared between states, you need to decide whether to inherit the value from the previous state when the state transitions, or to set an initial value.
