The following are the building blocks of Flow Orchestration:
Steps: Steps are discrete units of work that can be performed by a user or a system within a flow orchestration. Steps can have different types,such as user input steps, system action steps, decision steps, or subflow steps. Steps can also have different attributes, such as name, description, icon, input variables, output variables, or preconditions.
Stages: Stages are logical groupings of stepsthat represent phases or milestones within a flow orchestration. Stages can have different attributes, such as name, description, icon, entry criteria, exit criteria, or completion actions.
Work Items: Work Items are instances of flow orchestrations that track the progress and status of each execution. Work Items can have different attributes, such as name, description, owner, assignee, due date, priority, status, stage history, or step history.
