These are some BPMN symbols. Business Process Modeling Notation (BPMN) is a visual modeling language used to express corporate process workflows in business analysis software. It is similar to a flowchart in that it employs standardized images to show the participants, options, and process flow. It is a popular and straightforward image that all business stakeholders, including business users, business analysts, software engineers, and data architects, can readily grasp.
