There are three main events within business process modeling: start events, intermediate events, and end events. Events describe something that happens. They must either catch the result of the process or throw the results of the business flow. These two classes of events are known as "throwing" and "catching."

Start Event

start event Start events are exactly what they sound like. Each process must begin with a starting event. If the process is catching information (for example, receiving an email), Lucidchart allows the addition of a style event. You can easily add an event style by accessing the pop-up context panel inside the editor. In the case of a start event type, the event type is always caught. Lucidchart offers professional touches, like color fills and gradients via the Graphic panel, to help a start event stand out.

Intermediate Event

intermediate event An intermediate event is any event that occurs between a start and an end event. The intermediate event circle has a double line, and the event can catch or throw information. Connecting objects indicate the directional flow, like whether the event is catching or throwing. Users can find event types for intermediate events by using the pop-up context panel that appears when you add a new BPMN shape to the canvas.

End Event

data inputLastly, end events are styled with a single thick black line to indicate that it’s an end event. End events are always thrown because there is no process to catch after the final event.
