CA-JIS application [Ministry of Justice]

2008 • Logica
The Dutch Ministry of Justice (DJI) was in the process of developing a new application (CA-JIS) for managing information on the people entrusted to them (prisoners, illegal immigrants and people under hospital order) using case management.

Users: task flow and applications used

“Progressive disclosure” was used for the design of forms. When adding (for example) information about a court verdict, the relevant options and input fields are determined by the system (based on legislation) and presented to the user on the same page.

Responsibilities:

• Modeling the employee work-flow, analyzing user information obtained with questionnaires, contextual inquiries and field studies to determine the different types of users.
• User interface design, wire-frames
• Preparation and execution of paper prototyping sessions with which the usability of a series of design proposals for the new interface were tested.

As a result the usability of the interface design could be improved before any coding had been done, saving time and money.
