  Artificial Intelligence (AI) systems are being deployed around the globe in
critical fields such as healthcare and education. In some cases, expert
practitioners in these domains are being tasked with introducing or using such
systems, but have little or no insight into what data these complex systems are
based on, or how they are put together. In this paper, we consider an AI system
from the domain practitioner's perspective and identify key roles that are
involved in system deployment. We consider the differing requirements and
responsibilities of each role, and identify a tension between transparency and
privacy that needs to be addressed so that domain practitioners are able to
intelligently assess whether a particular AI system is appropriate for use in
their domain.
