BPMN (Business Process Model and Notation) is an OMG 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.
BPMN example showing a start event, a review task, an exclusive gateway, and approved or declined end events

A simple BPMN process: an application is received, reviewed, and routed by a gateway to an approved or declined outcome.

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.
