The process
We generally followed the approach shown in the corner, but the process was considerably shortened compared to non-Agile environments.
For the first couple of weeks, the development team learned iOS, while I studied research on what makes games fun. I produced several lists of game elements that we could build into our designs.
After that initial period, the work was a series of sprints. The first would involve the dev team starting on the core code while I laid out the basic UI.
I was brought on as a UX consultant. My main job was to ensure that the games we created were fun, playable, and something on which people wanted to spend money. However, I also ensured that they were usable and learnable.
