User Testing
It would have been magical if we got it right the first time, but we did not. In fact, it was more like the 8th or 9th try. User testing was a crucial part of the iteration process because we wanted to make sure that users could understand the tools and information presented to them. Making a tool that looks nice is one thing, but designing it to act as an extension to the human decision making process was our intended goal.
In order to accomplish this, we tested a variety of design layouts, colors, and navigational sequences. We took note of what worked and what could be improved.
