After the fields and a web form are created, you should configure how your workflow tasks will be processed, i.e. configure a workflow. A workflow is a sequence of steps that should be performed to get your work done.
In a workflow app, click Workflow. Modify the workflow diagram: drag statuses from the left part of the window and drop them into the canvas area. The status will turn into a workflow step. Double click on the step to specify its settings, e.g. assignee and transition rules. Interconnect steps with transitions. Double click on a transition to specify its settings. When finished, click Save Workflow.
