What elements were added to the BPMN diagram? Is there an example of a simple flow?

The following elements are usually added to a BPMN diagram:

• Pools — represent participants in the process or organization.
• Lanes — subdivisions within a pool, responsible for specific roles or departments.
• Events — start, intermediate, and end events of the process (e.g., process start, message receipt, completion).
• Tasks — actions or work that are performed.
• Sequence Flows — show the order of task execution.
• Message Flows — exchange messages between pools.
• Gateways — decision points, branching, or merging of flows.

Example of a simple flow:

1. Start Event — beginning of the process.
2. Task — perform an action (e.g., "Check application").
3. Gateway — make a decision (e.g., "Application approved?").
4. Task — if yes, perform "Process application".
5. End Event — end of the process.

This simple flow helps visualize the sequence of actions and decision points in a business process.
