Draft mode enables you to add flow shapes and connectors that reference other rules, even when those other rules do not yet exist. Using draft mode, you can run a process even if the rules that would otherwise be required, such as user interfaces and automated decisions, are missing. Flows with draft mode enabled will not run in a production environment and will display a Guardrail warning. To resolve the warning, turn off draft mode before releasing the application. When you create a flow rule, Pega defaults the flow rule to draft mode.
