![]() The parallel gateway can represent two or more concurrent tasks that are not dependent on each other. In this, a new event is started when each (exclusive) condition of the flow is met for the pre-defined event. Once the process is evaluated, it would break the flow into two or more paths that are mutually exclusive to each other.Īn event-based gateway is also associated with a single path, but it evaluates if an event has occurred to meet the requirements. The third category of Flow Objects in BPMN diagrams is for gateways that would depict any decision or the distribution of flow in the process. This is a special identity of a sub-process that would involve a payment or a transaction.Ī Call Activity is a global sub-process that you can take as a reference anywhere in the diagram. This symbol represents a group of tasks (that are known as sub-processes) that are combined in one place. It is the simplest activity that can’t be broken down further. This depicts any task that an event can perform. ![]() While there can be several BPMN symbols and meanings for activities, the following icons are mostly used. To depict them, we use dedicated icons with the start, intermediate, and end events that can give them further context.Ī business process can also have all kinds of activities that let us know how an event operates. The above-listed BPMN symbols are associated with no action, but we can have all kinds of events in a process. It represents the final stage of a business process model and is depicted by a circle with a solid border. It represents any event that comes in between the start and the end events and is depicted by a circle with double borders. It represents the starting of the business process and is depicted by a plain circle. Though, we can add more content to them by adding various icons. When it comes to a broader classification, there can be Start, Intermediate, or End events. There can be all kinds of artifacts that you can use such as annotations, data objects, or groups.Īs I have listed above, when it comes to the overall classification of BPMN symbols and meaning, Flow Objects can be of three types: Events, Activities, and Gateways.Įvents are the most important entities in any BPMN diagram as they constitute the backbone of the entire process. Lastly, you can also use artifacts to provide additional context to your BPMN diagrams. It consists of a “pool” that can depict an entire department of your company and various “lanes” that can help us distinguish processes in the system. Swimlane symbols are majorly used to organize our BPMN diagram and various entities in it. There can be 3 different kinds of connections in business processes that use directional arrows to represent their flow. These BPMN symbols are represented by diamond-shaped indicators.Ĭonnecting Objects simply depict how various other entities in a BPMN diagram are connected. Gateways: Gateways are considered as decision points in a BPMN diagram, and they can split or merge your process.We use rounded rectangles to represent activities in a BPMN diagram. They can imply a change or a task that an event undertook and led to any other event. Activities: Activities take place between different events in a BPMN diagram.It is simply represented by a circle and can accompany any other icon that depicts the present state of the event. Events: It depicts an event that takes place in the business process flow.Ideally, flow objects in a BPMN diagram can be of three types: Events, Activities, and Gateways. ![]() Flow ObjectsĪs the name suggests, these symbols depict the overall flow in a BPMN diagram and would make its backbone. Below is a list of the most commonly used electrical symbols. So to overcome this problem we use electronic symbols because they are easy to draw and this makes circuit easily. While there are all kinds of BPMN symbols, we can classify them into four major categories: Flow Objects, Connecting Objects, Swimlanes, and Artifacts.
