What events are there in BPMN?

In BPMN (Business Process Model and Notation), events are elements that indicate something happening and affecting the process. The main types of events:

• Start Events — initiate the process. For example, receiving a message, a timer, or a signal.
• Intermediate Events — occur during the process and can influence the flow, such as waiting for a message, a timer, or an error.
• End Events — signify the completion of a process or a process branch.

Each event can have different triggers or results, such as:

• Message
• Timer
• Error
• Signal
• Conditional

Events help model the process's reaction to external and internal factors, providing flexibility and manageability of business processes.
