====== Показывайте явно начало и завершение процесса ======

{{tag>событие начальное_событие конечное_событие}}

Всегда изображайте на диаграмме начальные и конечные события процесса.

===== Примечания =====

Согласно [[https://www.omg.org/spec/BPMN/2.0.2/PDF | спецификации BPMN]] начальное и конечное события не являются обязательными -
действие без входящих потоков управления считается неявным стартом, действие без исходящих потоков управления - неявным завершением.
Но диаграммы с неявным стартом и/или завершением могут трактоваться неправильно, поэтому их следует избегать.
