Примечания
- Некоторые авторы рекомендуют использовать стрелки, выходящие из действия, потому что это позволяет уменьшить количество элементов на диаграмме. Аргумент сомнительный: развилки полезны - они явно показывают, где процесс может пойти по разным маршрутам. Без них процессная логика становится менее прозрачной.
- Условные потоки, выходящие из действия, независимы, поэтому они эквивалентны развилке “и-или”.
