I did extensive research on the topic, consulted with many experts (such as Israeli trauma specialist Dr Asher Hirshberg); brought in subject matter experts (SMEs) to work closely with myself; attended numerous courses, symposiums, meetings, disaster drills; spent many hours observing at the famous MedStar shock/trauma facility in Washington DC, and toured many hospital critical care facilities. I also became an unofficial expert in the Hospital Emergency Incident Command System (HEICS), and did extensive client relations work.
I designed a tabletop prototype that covered the response of an entire hospital to a terrorist bomb scenario. I brought the development team (overseen by our subject-matter experts) through this prototype, so they could understand how the situation worked. I wrote the design documentation for the computer game, including spreadsheet-based data fields and mock-ups of the core user-interface.
I provided design leadership, guiding the development team in taking on the complex medical subject matter; boiling complicated materials down to a workable design, especially at the clinical level.
Code Orange was a project of Washington Hospital Center's ER1 initiative.
Here is a video of Code Orange in action, which gives a very rough sense of the interface (on which I also did core design work).
You can also see a video of myself moderating the tabletop prototype I designed for this project on BreakAway's homeland security page.
