Thanks Kelly. I have decided to go with the Survey 123 app and create a form for each user, based on the feature service. I have added a select one question and the choices available in the form will be limited to the domain values I want available for that specific user. I have also included a query expression in each form to only display the values of the field relative to that person This will allow the user to mark there task as finished for example and it will then become available to the next user in the process.
