Are you familiar with BPMN? How well do you know the notation, branching, and events?

BPMN (Business Process Model and Notation) is a standardized notation for modeling business processes, which allows visually describing the sequence of actions, events, and conditions in a process.

Main elements of BPMN:

• Events — indicate the start, intermediate, or end events of a process (e.g., receiving a message, timer, error).
• Activities — tasks or subprocesses that are performed.
• Sequence Flows — show the order of executing actions.
• Gateways — decision points that split the flow into several options (e.g., XOR — exclusive OR, AND — parallel execution).

Gateways allow modeling the logic of choosing the execution path depending on conditions or events. For example, after a request review task, an XOR gateway can be used to direct the process either for approval or rejection.

Events come in different types: start events (begin the process), intermediate events (occur during the process, e.g., waiting for a message), and end events (terminate the process).

Knowledge of BPMN is useful for system analysis, as it allows formalizing and visualizing business processes, facilitating communication between business and developers.
