A useful AI workflow starts with a clearly defined task. What goes in? What should happen next? When should a person take over?
Define the outcome first For a voice workflow, that outcome might be a qualified conversation or a structured follow-up. Model choice comes after the workflow is understood.
Design for exceptions Unclear answers, missing information and requests outside the scope need an explicit path. A human hand-off is part of a good product.
Measure useful progress Successful execution matters more than the number of automated steps.
