Hi Pamela,
We don't have a step by step guide, but...
1) Author the form with *all* the questions needed (supervisor & field worker) and publish to create the feature service
2) Create a new survey from that feature service; remove all the questions the field worker does not need. Publish the form - this is the field worker view
3) Create a new survey from that feature service; keep only the questions that the supervisor needs (if different than #1). Publish with the Inbox enabled - this is the supervisor form.
