![]() ![]() In BPMN, the processes are described by means of diagrams with a series of graphic elements. #Business process modelling notation symbols series Such visual presentation makes it easy for the users to understand the logic of a process.īPMN has been primarily developed to design and read both simple and complex diagrams of business processes. For that, the BPMN standard classifies the graphic elements by categories: as a result, the elements are easily recognized by the users who work with business process diagrams. There are five basic categories of BPMN elements. Each of them represent a unique aspect of business process. Swimlanes are graphical containers that represent participants of a process. There are two types of swimlanes - pools and lanes.įlow elements are elements that connect with each other to form business workflows. Flow elements are the primary elements that define the behavior of a process. There are three kinds of flow elements: Events, Activities and Gateways.įlow objects are not isolated, but rather connected in order to form a flow. The connectors that connect the flow objects are called connecting objects. There are four kinds of connecting objects: Sequence flows, message flows, associations and data associations.ĭata is mainly information needed or produced when executing a business process. There are four kinds of data: Data objects, data inputs, data outputs and data stores. ![]() ![]() Swimlane objects (aka: Swimlanes) in BPMN are rectangular boxes that represent participants of a business process. #Business process modelling notation symbols seriesĪ swimlane may contains flow objects that are performed by that lane (participant), except for black box that must have an empty body (we will talk about black box later on in this tutorial). ![]()
