In this interview, Arianna Rossi summarizes her definition of “legal design” as
[…] an interdisciplinary approach that promotes human-centered design to prevent or solve legal problems, by prioritizing the point of views of all the users of law.
She highlights the interdisciplinary nature of the discipline, the preventive approach (avoiding legal risk by good design), and the broad audiences far beyond legal practitioners, and stresses how important it is to recognize that legal design, just as design in general, is about more than making things visually appealing. Then, she gives some examples how legal design can be applied in relation to data protection.
In closing, the focus shifts to the importance of legal design as a (still young) practice that generates evidence to build upon:
We have not only to investigate a legal issue, but also to demonstrate why one intervention works better than another one. One of the most important insights that we can learn from a human-centred design approach is this evidence-based attitude enabling us to say that something works because we are able to explain how, why and for whom it works.
