What is BPMN?
BPMN stands for Business Process Model and Notation. It is an OMG and ISO 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 different types of gateways in our 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
- Timer Events
- Message Events
- Boundary Events
- Link Events
|BPMN objects within your process are connected to each other with a sequence flow which are designed by a solid arrow. Messages can be sent to other processes with a message flow, shown as a dashed line.
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.
|Call Activities are a specific type of activity that are used to call another business process that is contained inside a separate process diagram. Take a look at the Call Activities. 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 specific Pool and Lanes page.
|Message Flow allows you to have two or more processes interact by passing messages between processes Messageflow page.
