Dienst Justitiële Inrichtingen is the Dutch Agency of Correctional Institutions and is part of the Ministry of Security and Justice in The Netherlands. Annually the agency locks up about 70.000 people (called 'justitiabelen') in prisons, penitentiaries and juvenile justice institutions after a judge's ruling. A number of old information systems were used to register these lock-ups and had to be replaced by one overarching web application: CA-JIS (Capacity and Judicial Information System).

Lead User Experience
I conducted a field study at a number of institutions by shadowing the administration staff for several days. I made interaction designs for, among other things, the judicial search system, the judicial dossier and the registration of cases, criminal offenses and verdicts. I also conducted an expert review of the old registration system and paper prototyping sessions and usability testing of the new system. Finally, I drew up general interaction guidelines for the CA-JIS developers.
