I identified key interaction design issues on the current booking system of the Mercy Heart Centre (Dunedin, NZ). Using a "quick and dirty" ethnographic approach, I performed interviews and observations with the system administrators to collect the data sources that later informed the development of a report. This report includes suggestions for the design of new features and re-design of existing features of the booking system. Comissioned by MHC, the report was written in approx. 25 hours.
