By using SpiffWorkflow, a client can create the BPMN diagram and have their product work without the need for you to modify the Python code, thus improving response and turnaround time.
| Exclusive gateway | | Evaluates the state of the business process and, based on the condition, diverges the flow into one or more mutually exclusive paths. |
| Event-based gateway |  | An event-based gateway is similar to an exclusive gateway in that both involve one path in the flow. However, with an event-based gateway, you evaluate which event has occurred, not which condition has been met. |
| Inclusive gateway |  | An inclusive gateway diverges the process flow into one or more flows. |
| Complex gateway |  | Complex gateways are used only for the most intricate flows in the business process. They use words instead of symbols and thus require more descriptive text. |
| Service |  | A task that utilizes a Web service, an automated application, or other types of service to complete the task. |
| Send | | A task that sends a message to another pool. The task is completed once the message has been sent. |
| Receive |  | A Receive Task indicates that the process has to wait for a message to arrive in order to continue. The task is completed once the message has been received. |
| User |  | A User Task denotes that a human performer completes the task with the help of a software application. |
| Manual |  | A Manual Task is a task performed without the aid of any business process execution engine or application. |
| Business Rule || A Business Rule Task provides a mechanism for a process to supply input to a Business Rules Engine and then obtain the output provided by the Business Rules Engine. |
Artifacts are used to provide additional information or documentation within a process.
They include data objects (which represent information or data needed for the process), annotations (which provide explanatory or descriptive text), and groups (which are used to visually group related elements).
| Data Object |<divstyle="height:50px;width:50px">  | Data objects can represent data input to the process, data resulting from the process, or data that needs to be collected. |
| Data Storage | | Data storage facilitates the storage or access of data associated with a business model. If your process produces any data, it will become necessary to store that data. |
| Group | <divstyle="height:50px;width:50px">  | Groups organize tasks or processes that are significant in the overall process. |
| Annotation | <divstyle="height:50px;width:50px">  | Annotations allow you to describe the business process and flow objects in greater detail. |
These elements can be arranged either horizontally or vertically.
Not only do swimlanes organize activities into separate categories, but they also reveal delays, inefficiencies, and the individuals responsible for each step in a process.
