As industry leaders, our CTO asked me to work on a secret project that would capture the new (at the time) rugged mobile device market. Based on an inexpensive Android-based circuit board, I was to craft use cases and a device case for user-worn communication command and control. After conducting dozens of user interviews, I developed scenarios and use cases for the new device. After multiple rapidly developed prototypes made from cardboard, duct tape, and finally ABS materials, I was able to focus efforts on a case and feature set. Working with outside engineering resources, the case, buttons, and connectors were developed for the first alpha release user testing. In the end, it became our corporate president's leading product to promote. It was adopted by over 100,000 troops in the first year.
