# What is BPMN?
> BPMN (Business Process Model and Notation) is an OMG standard for modeling business processes visually as tasks, gateways, and events - portable and executable.
**BPMN (Business Process Model and Notation)** is an
[OMG](https://www.omg.org/bpmn/) standard for modeling **business processes and
workflows** visually. Where DMN and DRL decide *what* the answer is, BPMN
orchestrates *when and in what order* work happens — the sequence of **tasks,
gateways, and events** that move work through to completion.
A process is drawn as a flow that everyone can read: it **starts** with an event,
runs **tasks** (work performed by people or systems), branches at **gateways**
(decision points), and **ends** with an outcome. Because it is a portable,
vendor-neutral standard, the same diagram can be reviewed by business teams and
executed directly by a process engine.
In practice, BPMN and DMN work together: the process (BPMN) calls out to a
decision (DMN or DRL) at a gateway, then continues based on the answer.
