Letsflow is a human-centric workflow automation engine that blends automation with human decision-making, enabling dynamic interactions between people and automated steps.

The scenario models a process as a fine-state machine. The actors are persons, organizations, or systems that can participate in the process by performing actions. Which actions can be performed depends on the current state of the process. By executing an action, the process can transition to a different state.
