 The drawbacks are:
- * The diagrams can become quite large. Our diagram just shows some states. Reality might be much more complex.

- * Refining behavior in concurrent regions makes the parent state containing the regions bigger and bigger. Depending on the modeling tool features’ this often has the consequence that a lot of work is going into moving states around to make space for new ones instead on focussing on the design work itself.

 The following figures show the leader machine and then two simplified examples of follower state machines.
-Figure 2a: Leader machine. It just sends events to the follower to trigger actions.
