| Workflow Sequence | Definition |
| Hybrid | An approval workflow that combines elements of both Serial and Parallel Approval Sequences |
| Parallel | Triggers multiple requests in one step that all occur at the same time (i.e. in parallel) and do not rely on each other for execution. |
| Serial | After a trigger, the flow moves to the next step for action. Most use cases relate to a series of sequential requests or actions. |
