What is BPMN?
BPMN stands for Business Process Model and Notation, it is a standard to design and document business processes in a graphical notation. You can find more details about the specification at bpmn.org.
The basics of BPMN
BPMN uses a graphical notation to let the user designs and explains its business processes, the main four components are:
|Activities are displayed as round rounded-corner rectangle and represent what work has to be done. Tasks are a really good start point to understand how activities works.|
|Gateways are represented as diamond shape and used to split and merge the flow. You can find more details about the current implementation here.|
|Events are displayed as circles and used to trigger actions like starting a flow instance. Read the following sections get started with events:
- Start and Stop Events
- Timers Events
- Boundary Events
- Link Events
|BPMN objects are connected each others with a sequence flow which are designed by an arrow.|
After being familiar with the previous elements, you may want to take a look at the advanced objects
|Sub Processes are a specific type of activity that are used to make diagrams cleaner by encapsulating business process inside a business process. Take a look at the Sub Processes. page to know how to use it.|
|Pools and Lanes show who should perform a task and are represented as a rectangle, one pool can contains one to many lanes. See the sepcific Pool and Lanes page.|
