Components

TWU model edit view showing entities, actions, events, and outcomes sections

​
Entities

Objects that work operates on. Define the data structure for entities in your model.

​
Actions

Operations performed on entities. Actions define what work can be done.

​
Events

State changes or occurrences. Events track what happens during work execution.

​
Outcomes

Results with expressions. Outcomes define how to compute results from work operations.

​
Lifecycle

  1. Create model with draft version
  2. Edit draft version (entities, actions, events, outcomes)
  3. Publish draft to make it available
  4. Create new version for changes (maintains history)
  5. Archive old versions when deprecated
