How can we know if we're designing ethically? What unintended consequences could result from our decisions? What can we do to maximize good and minimize harm in digital product design? These urgent questions were addressed over 4 days at the Academics and Practioners Roundtable at the 2018 IA Summit. One result was the development of a prototype for guiding teams in incorporating ethical design into their products. Stacy Surla walks through the tool and test its usefulness in an interactive session at the September UXDC meetup.
