  We introduce the notion of a data-first design study which is triggered by
the acquisition of real-world data instead of specific stakeholder analysis
questions. We propose an adaptation of the design study methodology framework
to provide practical guidance and to aid transferability to other data-first
design processes. We discuss opportunities and risks by reflecting on two of
our own data-first design studies. We review 64 previous design studies and
identify 16 of them as edge cases with characteristics that may indicate a
data-first design process in action.
