I was the UX lead on this project. I integrated the UI styles from similar components in a sister project that was being simultaneously designed. I also integrated two other designer's designs into this UX/UI series whilst maintaining consistency. :)
This entire UX series consists of about seventy screens. It took me and the team sixty days to complete the design and development of the UI.
We just wrapped it up last night at 10PM actually. I'm feeling pretty good about where we landed and the client seems happy as a lark.
The process: Tank filling, UX lowfis, UI hifis, test UI hifis, final sign-off, pair dev-sign, and test.
